Reframing Ecosystem Management in the Era of Climate Change: Issues and Knowledge from Forests. Mori, A. S., Spies, T. A., Sudmeier-Rieux, K., & Andrade, A. 165:115–127. Paper doi abstract bibtex We discuss ” ecosystem management (EM)” to face contemporary climate change issues. EM focuses on sustaining ecosystems to meet both ecological and human needs. EM plans have been largely developed independent of concerns about climate change. However, EM is potentially effective for climate change mitigation and adaptation. We provide the principle guidelines based on EM to adaptively tackle the issues. Climate change is one of the significant concerns in land and resource management, creating an urgent need to build social-ecological capacity to address widespread and uncertain environmental changes. Given the diversity and complexity of ecological responses to climate change ” ecosystem management” approaches are needed to provide solutions for meeting both ecological and human needs, while reducing anthropogenic warming and climate-related impacts on society. For instance, ecosystem management can contribute to a reduction in the greenhouse gas emissions through improved land-use and reduced deforestation at a regional scale. Further, conserving and restoring naturally-functioning ecosystems, which is often one of the goals of ecosystem management can significantly contribute to buffering ecological responses to climate extremes such as droughts and wildfires. Moreover, ecosystem management helps build capacity for learning and adaptation at multiple scales. As a result, societies will be better prepared to respond to surprises and uncertainties associated with climate change. In this regard, it is imperative to reframe climate change issues based on the ecosystem approach. Although climate change and ecosystem management plans have largely developed independently, it is now essential for all stakeholders to work together to achieve multiple goals. The ecosystem-based approaches can enable flexible and effective responses to the uncertainties associated with climate change. Reframing ecosystem management helps to face an urgent need for reconsideration and improvement of social-ecological resilience in order to mitigate and adapt to the changing climate.

In this article, we have discussed reframing ecosystem management as an effective way to address the uncertainties of climate change. It is therefore necessary to adopt flexible and robust management strategies that consider various scenarios, rather than adopting a single measure. Similar to climate change, which is intricately connected to other issues beyond physical climatic change, ecological issues are deeply associated with global issues.

[Excerpt: Conclusion]
Novel approaches underpinned by sociology, ecology and climate science are necessary to perform assessments that reflect the many roles that ecosystem management can play in mitigating and adapting to climate change. No single method and focal scale for addressing the effects or causes of climate change exists. Indeed, there are often trade-offs such as those between the goals of building resilience (learning from failure) and reducing vulnerability (minimizing failure) (Adger et al., 2008), suggesting some policies aimed at minimizing exposure to any hazards at the regional scale can potentially conflict with the proactive implementation of adaptive management at the local scale. In this article, we have discussed reframing ecosystem management as an effective way to address the uncertainties of climate change. It is therefore necessary to adopt flexible and robust management strategies that consider various scenarios, rather than adopting a single measure. Similar to climate change, which is intricately connected to other issues beyond physical climatic change, ecological issues are deeply associated with global issues. A number of environmental policies and plans have been historically developed with little consideration of climate instability. Among them, our attempt that integrates different management considerations into the common context lends a strong support for the objectives and approaches of ecosystem management as an effective tool to face climate change uncertainties.

Advances in Pan-European Flood Hazard Mapping. Alfieri, L., Salamon, P., Bianchi, A., Neal, J., Bates, P., & Feyen, L. 28(13):4067–4077. Paper doi abstract bibtex Flood hazard maps at trans-national scale have potential for a large number of applications ranging from climate change studies, reinsurance products, aid to emergency operations for major flood crisis, among others. However, at continental scales, only few products are available, due to the difficulty of retrieving large consistent data sets. Moreover, these are produced at relatively coarse grid resolution, which limits their applications to qualitative assessments. At finer resolution, maps are often limited to country boundaries, due to limited data sharing at trans-national level. The creation of a European flood hazard map would currently imply a collection of scattered regional maps, often lacking mutual consistency due to the variety of adopted approaches and quality of the underlying input data. In this work, we derive a pan-European flood hazard map at 100\,m resolution. The proposed approach is based on expanding a literature cascade model through a physically based approach. A combination of distributed hydrological and hydraulic models was set up for the European domain. Then, an observed meteorological data set is used to derive a long-term streamflow simulation and subsequently coherent design flood hydrographs for a return period of 100\,years along the pan-European river network. Flood hydrographs are used to simulate areas at risk of flooding and output maps are merged into a pan-European flood hazard map. The quality of this map is evaluated for selected areas in Germany and United Kingdom against national/regional hazard maps. Despite inherent limitations and model resolution issues, simulated maps are in good agreement with reference maps (hit rate between 59\,% and 78\,%, critical success index between 43\,% and 65%), suggesting strong potential for a number of applications at the European scale.

Indeed, their first monumental hydrological construction projects were concerned with irrigation and transport: around 2200 b.c., the first navigable canal, the Shatt-el-hai, linking the Tigris and Euphrates rivers in Mesopotamia, was excavated; in the 6th century b.c., a canal was built which joined the Nile with the northern Red Sea and, in the 4th century b.c., the Grand Canal in China connected Peking to Hangzhou, a distance of almost 1,000 km.The technological innovations of the 18th century led to an expansion of the network of navigable inland waterways, followed in the 19th century and the early part of the 20th century by the excavation of two interoceanic canals: the Suez Canal, which opened a direct route from the Mediterranean Sea to the Indo-Pacific Ocean, and the Panama Canal, which afforded passage between the Atlantic and Eastern Pacific oceans. Canals connecting rivers over watersheds or seas across narrow land bridges ” dissolve” natural barriers to the dispersal of aquatic organisms, thereby furnishing these with many opportunities for natural dispersal as well as for shipping-mediated transport.

Attributing Extreme Fire Risk in Western Canada to Human Emissions. Kirchmeier-Young, M. C., Zwiers, F. W., Gillett, N. P., & Cannon, A. J. 144(2):365–379. Paper doi abstract bibtex Canada is expected to see an increase in fire risk under future climate projections. Large fires, such as that near Fort McMurray, Alberta in 2016, can be devastating to the communities affected. Understanding the role of human emissions in the occurrence of such extreme fire events can lend insight into how these events might change in the future. An event attribution framework is used to quantify the influence of anthropogenic forcings on extreme fire risk in the current climate of a western Canada region. Fourteen metrics from the Canadian Forest Fire Danger Rating System are used to define the extreme fire seasons. For the majority of these metrics and during the current decade, the combined effect of anthropogenic and natural forcing is estimated to have made extreme fire risk events in the region 1.5 to 6 times as likely compared to a climate that would have been with natural forcings alone.

Well below 2 °C: Mitigation Strategies for Avoiding Dangerous to Catastrophic Climate Changes. Xu, Y. & Ramanathan, V. 114(39):10315–10323. Paper doi abstract bibtex The historic Paris Agreement calls for limiting global temperature rise to ” well below 2 °C.” Because of uncertainties in emission scenarios, climate, and carbon cycle feedback, we interpret the Paris Agreement in terms of three climate risk categories and bring in considerations of low-probability (5\,%) high-impact (LPHI) warming in addition to the central (∼50\,% probability) value. The current risk category of dangerous warming is extended to more categories, which are defined by us here as follows: $>$1.5 °C as dangerous; $>$3 °C as catastrophic; and $>$5 °C as unknown, implying beyond catastrophic, including existential threats. With unchecked emissions, the central warming can reach the dangerous level within three decades, with the LPHI warming becoming catastrophic by 2050. We outline a three-lever strategy to limit the central warming below the dangerous level and the LPHI below the catastrophic level, both in the near term ($<$2050) and in the long term (2100): the carbon neutral (CN) lever to achieve zero net emissions of CO2, the super pollutant (SP) lever to mitigate short-lived climate pollutants, and the carbon extraction and sequestration (CES) lever to thin the atmospheric CO2 blanket. Pulling on both CN and SP levers and bending the emissions curve by 2020 can keep the central warming below dangerous levels. To limit the LPHI warming below dangerous levels, the CES lever must be pulled as well to extract as much as 1 trillion tons of CO2 before 2100 to both limit the preindustrial to 2100 cumulative net CO2 emissions to 2.2 trillion tons and bend the warming curve to a cooling trend. [Excerpt: Summary] Basically, for a safe climate, all three levers (CN, SP, and CES) must be deployed as soon as possible. The CN and SP levers must be deployed by 2030 and 2020, respectively; the cumulative CO2 emissions from preindustrial must be limited to 2.2 trillion tons of CO2 (or 0.6 trillion tons of carbon); and the CES lever should extract and sequester as much as 1 trillion tons of CO2 (CES1t), depending on when the CN lever is deployed. If the CN lever is deployed as early as 2020, the required CES is much less than 1 trillion tons.

abstract = {The historic Paris Agreement calls for limiting global temperature rise to ” well below 2 °C.” Because of uncertainties in emission scenarios, climate, and carbon cycle feedback, we interpret the Paris Agreement in terms of three climate risk categories and bring in considerations of low-probability (5\,\%) high-impact (LPHI) warming in addition to the central (∼50\,\% probability) value. The current risk category of dangerous warming is extended to more categories, which are defined by us here as follows: {$>$}1.5 °C as dangerous; {$>$}3 °C as catastrophic; and {$>$}5 °C as unknown, implying beyond catastrophic, including existential threats. With unchecked emissions, the central warming can reach the dangerous level within three decades, with the LPHI warming becoming catastrophic by 2050. We outline a three-lever strategy to limit the central warming below the dangerous level and the LPHI below the catastrophic level, both in the near term ({$<$}2050) and in the long term (2100): the carbon neutral (CN) lever to achieve zero net emissions of CO2, the super pollutant (SP) lever to mitigate short-lived climate pollutants, and the carbon extraction and sequestration (CES) lever to thin the atmospheric CO2 blanket. Pulling on both CN and SP levers and bending the emissions curve by 2020 can keep the central warming below dangerous levels. To limit the LPHI warming below dangerous levels, the CES lever must be pulled as well to extract as much as 1 trillion tons of CO2 before 2100 to both limit the preindustrial to 2100 cumulative net CO2 emissions to 2.2 trillion tons and bend the warming curve to a cooling trend.
[Excerpt: Summary] Basically, for a safe climate, all three levers (CN, SP, and CES) must be deployed as soon as possible. The CN and SP levers must be deployed by 2030 and 2020, respectively; the cumulative CO2 emissions from preindustrial must be limited to 2.2 trillion tons of CO2 (or 0.6 trillion tons of carbon); and the CES lever should extract and sequester as much as 1 trillion tons of CO2 (CES1t), depending on when the CN lever is deployed. If the CN lever is deployed as early as 2020, the required CES is much less than 1 trillion tons.

Enhanced Poleward Propagation of Storms under Climate Change. Tamarin-Brodsky, T. & Kaspi, Y. Paper doi abstract bibtex Earth's midlatitudes are dominated by regions of large atmospheric weather variability – often referred to as storm tracks – which influence the distribution of temperature, precipitation and wind in the extratropics. Comprehensive climate models forced by increased greenhouse gas emissions suggest that under global warming the storm tracks shift poleward. While the poleward shift is a robust response across most models, there is currently no consensus on what the underlying dynamical mechanism is. Here we present a new perspective on the poleward shift, which is based on a Lagrangian view of the storm tracks. We show that in addition to a poleward shift in the genesis latitude of the storms, associated with the shift in baroclinicity, the latitudinal displacement of cyclonic storms increases under global warming. This is achieved by applying a storm-tracking algorithm to an ensemble of CMIP5 models. The increased latitudinal propagation in a warmer climate is shown to be a result of stronger upper-level winds and increased atmospheric water vapour. These changes in the propagation characteristics of the storms can have a significant impact on midlatitude climate.

Impacts of Climate Change on European Forests and Options for Adaptation. Lindner, M., Schopf, A., Kremer, A., Delzon, S., Barbati, A., Marchetti, M., Corona, P., Garcia-Gonzalo, J., Kolström, M., Green, T., Reguera, R., Maroschek, M., Seidl, R., Lexer, M. J., & Netherer, S. Paper abstract bibtex [Excerpt] This study compiles and summarizes the existing knowledge about observed and projected impacts of climate change on forests in Europe and reviews options for forests and forestry to adapt to climate change. It has been commissioned by the Directorate General for Agriculture and Rural Development of the European Commission as an initial exploration of this complex issue. Forests are particularly sensitive to climate change, because the long life-span of trees does not allow for rapid adaptation to environmental changes. Adaptation measures for forestry need to be planned well in advance of expected changes in growing conditions because the forests regenerated today will have to cope with the future climate conditions of at least several decades, often even more than 100 years. Impacts of climate change and adaptation options were reviewed by synthesizing the existing knowledge from scientific literature, complemented with expert assessments. On-going and planned adaptation measures in EU27 Member States were surveyed with a questionnaire. The exposure to climate change was analysed by reviewing latest climate change scenario projections. The main impact factors affecting forests under climate change were reviewed. Next, the sensitivity to and potential impacts of climate change were analysed. After reviewing different components of the adaptive capacity of forests and forestry, vulnerability to climate change and related risks and opportunities were highlighted. Possible adaptation measures to respond to climate change were analysed. The results are presented for four main bioclimatic zones: Boreal, Temperate Oceanic, Temperate Continental, and the Mediterranean.

Climate Change and Forest Fires Synergistically Drive Widespread Melt Events of the Greenland Ice Sheet. Keegan, K. M., Albert, M. R., McConnell, J. R., & Baker, I. 111(22):7964–7967. Paper doi abstract bibtex [Significance] Through an examination of shallow ice cores covering a wide area of the Greenland Ice Sheet (GIS), we show that the same mechanism drove two widespread melt events that occurred over 100 years apart, in 1889 and 2012. We found that black carbon from forest fires and rising temperatures combined to cause both of these events, and that continued climate change may result in nearly annual melting of the surface of the GIS by the year 2100. In addition, a positive feedback mechanism may be set in motion whereby melt water is retained as refrozen ice layers within the snow pack, causing lower albedo and leaving the ice sheet surface even more susceptible to future melting. [Abstract] In July 2012, over 97\,% of the Greenland Ice Sheet experienced surface melt, the first widespread melt during the era of satellite remote sensing. Analysis of six Greenland shallow firn cores from the dry snow region confirms that the most recent prior widespread melt occurred in 1889. A firn core from the center of the ice sheet demonstrated that exceptionally warm temperatures combined with black carbon sediments from Northern Hemisphere forest fires reduced albedo below a critical threshold in the dry snow region, and caused the melting events in both 1889 and 2012. We use these data to project the frequency of widespread melt into the year 2100. Since Arctic temperatures and the frequency of forest fires are both expected to rise with climate change, our results suggest that widespread melt events on the Greenland Ice Sheet may begin to occur almost annually by the end of century. These events are likely to alter the surface mass balance of the ice sheet, leaving the surface susceptible to further melting.

A firn core from the center of the ice sheet demonstrated that exceptionally warm temperatures combined with black carbon sediments from Northern Hemisphere forest fires reduced albedo below a critical threshold in the dry snow region, and caused the melting events in both 1889 and 2012. We use these data to project the frequency of widespread melt into the year 2100. Since Arctic temperatures and the frequency of forest fires are both expected to rise with climate change, our results suggest that widespread melt events on the Greenland Ice Sheet may begin to occur almost annually by the end of century. These events are likely to alter the surface mass balance of the ice sheet, leaving the surface susceptible to further melting.},

Statistical Significance of Seasonal Warming/Cooling Trends. Ludescher, J., Bunde, A., & Schellnhuber, H. J. 114(15):E2998-E3003. Paper doi abstract bibtex [Significance] The question whether a seasonal climatic trend (e.g., the increase of spring temperatures in Antarctica in the last decades) is of anthropogenic or natural origin is of great importance because seasonal climatic trends may considerably affect ecological systems, agricultural yields, and human societies. Previous studies assumed that the seasonal records can be treated as independent and are characterized by short-term memory only. Here we show that both assumptions, which may lead to a considerable overestimation of the trend significance, do not apply to temperature data. Combining Monte Carlo simulations with the Holm-Bonferroni method, we demonstrate how to obtain reliable estimates of the statistical significance of seasonal climatic trends and apply our method to representative atmospheric temperature records of Antarctica. [Abstract] The question whether a seasonal climate trend (e.g., the increase of summer temperatures in Antarctica in the last decades) is of anthropogenic or natural origin is of great importance for mitigation and adaption measures alike. The conventional significance analysis assumes that (i) the seasonal climate trends can be quantified by linear regression, (ii) the different seasonal records can be treated as independent records, and (iii) the persistence in each of these seasonal records can be characterized by short-term memory described by an autoregressive process of first order. Here we show that assumption ii is not valid, due to strong intraannual correlations by which different seasons are correlated. We also show that, even in the absence of correlations, for Gaussian white noise, the conventional analysis leads to a strong overestimation of the significance of the seasonal trends, because multiple testing has not been taken into account. In addition, when the data exhibit long-term memory (which is the case in most climate records), assumption iii leads to a further overestimation of the trend significance. Combining Monte Carlo simulations with the Holm-Bonferroni method, we demonstrate how to obtain reliable estimates of the significance of the seasonal climate trends in long-term correlated records. For an illustration, we apply our method to representative temperature records from West Antarctica, which is one of the fastest-warming places on Earth and belongs to the crucial tipping elements in the Earth system.

Climate Change and the Future for Broadleaved Tree Species in Britain. Broadmeadow, M. S. J., Ray, D., & Samuel, C. J. A. 78(2):145–161. Paper doi abstract bibtex The most recent climate change predictions for the UK indicate a warming of between 2 and 5°C by the end of this century, with drier summers and wetter winters also anticipated across the majority of the country. Changes are predicted to be more extreme in the southern half of the UK, where severe summer droughts will become commonplace. Although rising atmospheric CO2 levels are likely to increase productivity through 'fertilizing' photosynthesis, water limitation in southern England is likely to lead to an overall reduction in growth and increase in drought-induced mortality. Incorporation of, the climate change scenarios within the GIS model Ecological Site Classification indicates that in isolation, the effects of climate change will result in significant changes in species suitability. Under current definitions the majority of native broadleaf species are predicted to become unsuitable for commercial timber production in southern England. Genetic variability in local native populations may enable a degree of adaptation. Existing trials of ash (Fraxinus excelsior L.) suggest that the best performing provenances are those from regions with a climate similar to that of the trial site. The selection of a provenance for climate change adaptation should be from a region with a current climate well matched to a planting site's predicted climate of the future. Climate matching analysis indicates that coastal areas of western France experience a climate similar to that predicted for southern England by 2050, while the more extreme scenarios predict climates better matched to the Mediterranean region at high elevation by the end of the century. The scale of climate change predictions indicates that, in southern England, native broadleaf species may be unsuitable for timber production on some soils. The planting of non-native species may need to be considered to maintain woodland cover and ensure a viable hardwood timber industry.

Inter-Relationships between Treeline Position, Species Diversity, Land Use and Climate Change in the Central Scandes Mountains of Norway. Hofgaard, A. 6(6):419+. Paper doi abstract bibtex Vegetation samples collected along altitudinal transects through the treeline ecotone in the central Scandes Mountains, Norway, were used to analyse the relationships between species diversity, species turnover and the performance of the tree layer. The study area has a long history of extensive grazing by domestic animals. The floristic composition showed a continuous change along the boreal-alpine gradient. The number of species was more or less constant throughout 600 altitudinal m centred around the treeline, and the floristic similarity between neighbouring altitudes did not show any abrupt changes at any particular altitude. The treeline position (Betula pubescens Ehrh.) spanned 190 altitudinal m (range 980-1170 m a.s.l.). The number of trees and the basal area each decreased continuously with increasing altitude from 300 altitudinal m below the treeline. The number of birch saplings also decreased from c. 150 m below the treeline towards higher altitudes. Viable, but browsed populations of birch were present along the whole length of all transects, irrespective of aspect and geological substrate, with saplings present up to summit positions at 420 altitudinal m above the treeline. Due to browsing by sheep, mean sapling height at all altitudes above the treeline was 0.2 m. The results are discussed in terms of land use and climate change. It is concluded that future vegetation responses to diminished grazing pressure are likely to override responses forced by changing climate. Such responses could easily be misinterpreted as being governed by climate change, rather than by changes in land use.

Paper doi abstract bibtex [Excerpt] Forests respond differently to changes in climate depending on individual site characteristics and tree status. Site conditions may buffer or boost impacts of heat, drought, and storm events. Considering contemporary changes in climate (Christensen et al. 2007), warming may increase forest productivity in those parts of Europe where growth resources like soil water are not limiting (Nabuurs et al. 2002). However, under conditions of limited resource supply and changed disturbance regime, we may expect a reduction of forest productivity and vitality (Lindner et al. 2010). Major climatic impacts on forests include both singular extreme events (changing climate variability) that are difficult to predict in time and location, as well as less obvious gradual changes (changing mean values) (Bolte et al. 2010; Reyer et al. 2013).

Projections of Climate Change Indices of Temperature and Precipitation from an Ensemble of Bias-Adjusted High-Resolution EURO-CORDEX Regional Climate Models. Dosio, A. 121(10):2015JD024411-5511. Paper doi abstract bibtex Statistical bias-adjustment of climate models' outputs is being increasingly used for assessing the impact of climate change on several sectors. It is known that these techniques may alter the mean climate signal of the adjusted variable; however, the effect on the projected occurrence of climate extremes is less commonly investigated. Here the outputs of an ensemble of high-resolution (0.11°) regional climate models (RCM) from the Coordinated Regional-climate Downscaling Experiment for Europe (EURO-CORDEX) have been bias adjusted, and a number of climate indices from the Expert Team on Climate Change Detection and Indices have been calculated for the present (1981-2010) and future (2071-2100) climate. Indices include absolute-thresholds indices, percentile-based indices, and indices based on the duration of an event. Results show that absolute-threshold indices are largely affected by bias adjustment, as they depend strongly on both the present mean climate value (usually largely biased in the original RCMs) and its shift under climate change. The change of percentile-based indices is less affected by bias adjustment, as that of indices based on the duration of an event (e.g., consecutive dry days or heat waves) although the present climate value can differ between original and bias-adjusted results. Indices like R95ptot (the total amount of precipitation larger than the 95th reference percentile) are largely affected by bias adjustment, although, when analyzing an ensemble of RCMs, the differences are usually smaller than, or comparable to, the intermodel variability.

This data leads to statements like ” temperature increase is expected to exceed 2.6°C” or similar and remain fuzzy to non-experts in climate research. The Climate Twins application is designed to communicate climate changes in an intuitive and understandable way by showing regions which have now similar climate conditions according to a given Point of Interest (POI) in the future.

A 3,500-Year Tree-Ring Record of Annual Precipitation on the Northeastern Tibetan Plateau. Yang, B., Qin, C., Wang, J., He, M., Melvin, T. M., Osborn, T. J., & Briffa, K. R. 111(8):2903–2908. Paper doi abstract bibtex [Significance] This paper describes the production and climatic interpretation of a tree-ring width chronology that is currently the longest, absolutely dated series produced for the northeastern Tibetan Plateau and one of the longest in the world. The method of chronology construction enables comparison of variations in precipitation totals over long timescales as well as shorter periods. Precipitation in this region during the last 50 years has been historically high – likely higher than for any equivalent length period in at least 3,500 years, even when considering the chronology and interpretational uncertainty. Notable dry periods occurred in the 4th century BCE and in the second half of the 15th century CE. [Abstract] An annually resolved and absolutely dated ring-width chronology spanning 4,500 y has been constructed using subfossil, archaeological, and living-tree juniper samples from the northeastern Tibetan Plateau. The chronology represents changing mean annual precipitation and is most reliable after 1500 B.C. Reconstructed precipitation for this period displays a trend toward more moist conditions: the last 10-, 25-, and 50-y periods all appear to be the wettest in at least three and a half millennia. Notable historical dry periods occurred in the 4th century BCE and in the second half of the 15th century CE. The driest individual year reconstructed (since 1500 B.C.) is 1048 B.C., whereas the wettest is 2010. Precipitation variability in this region appears not to be associated with inferred changes in Asian monsoon intensity during recent millennia. The chronology displays a statistical association with the multidecadal and longer-term variability of reconstructed mean Northern Hemisphere temperatures over the last two millennia. This suggests that any further large-scale warming might be associated with even greater moisture supply in this region.

This suggests that any further large-scale warming might be associated with even greater moisture supply in this region.},

Identifying Refugia from Climate Change Using Coupled Ecological and Genetic Data in a Transitional Mediterranean-Temperate Tree Species. Temunović, M., Frascaria-Lacoste, N., Franjić, J., Satovic, Z., & Fernández-Manjarrés, J. F. 22(8):2128–2142. Paper doi abstract bibtex Populations occurring in areas of overlap between the current and future distribution of a species are particularly important because they can represent ” refugia from climate change”. We coupled ecological and range-wide genetic variation data to detect such areas and to evaluate the impacts of habitat suitability changes on the genetic diversity of the transitional Mediterranean-temperate tree Fraxinus angustifolia. We sampled and genotyped 38 natural populations comprising 1006 individuals from across Europe. We found the highest genetic diversity in western and northern Mediterranean populations, as well as a significant west to east decline in genetic diversity. Areas of potential refugia that correspond to approximately 70\,% of the suitable habitat may support the persistence of more than 90\,% of the total number of alleles in the future. Moreover, based on correlations between Bayesian genetic assignment and climate, climate change may favour the westward spread of the Black Sea gene pool in the long term. Overall, our results suggest that the northerly core areas of the current distribution contain the most important part of the genetic variation for this species and may serve as in situ macrorefugia from ongoing climate change. However, rear-edge populations of the southern Mediterranean may be exposed to a potential loss of unique genetic diversity owing to habitat suitability changes unless populations can persist in microrefugia that have facilitated such persistence in the past.

Projecting Future Burnt Area in the EU-Mediterranean Countries under IPCC SRES A2/B2 Climate Change Scenarios. Amatulli, G., Camia, A., & San-Miguel-Ayanz, J. Paper abstract bibtex The goal of this work is to use the results of statistical modelling of historical (1985-2004) monthly burnt areas in European Mediterranean countries, as a function of monthly weather data and derived fire danger indexes, and to analyse potential trends under present and future climate conditions. Meteorological variables were extracted from the ECMWF, and the FWI system components were computed from 1961 until 2004. Monthly averages of the indexes were used as explanatory variables in a stepwise multiple linear regression analysis, to estimate the monthly burnt areas in each of the five most affected Mediterranean countries of Europe. Significant regression equations and satisfactory coefficient of determinations were found, although with remarkable differences among countries. Two IPCC SRES climate change scenarios (A2/B2) were simulated using the the regional climate model HIRHAM. The multiple regression models were than applied to the A2/B2 scenarios results to predict the potential burnt areas in each country. The models pointed out tangible changes in the potential burnt area extent for the future scenarios compared to the actual conditions.

Climate Change. Atlantic Current Can Shut down for Centuries, Disrupting Climate. Kerr, R. A. 343(6173):831. Paper doi abstract bibtex [excerpt] For decades, climate scientists have cast a worried eye at the grand ocean circulation that draws warm southern waters into the North Atlantic. A shutdown due to global warming – a possibility hinted at by some climate models – would not bury Manhattan under a tsunami of ice, as one Hollywood disaster movie had it. But it would unsettle climate around the North Atlantic and beyond. Now, researchers have hard evidence that the real Atlantic circulation did indeed abruptly slow or perhaps even stop for centuries at a time more than 100,000 years ago, when the world was only a bit warmer than today.

Impact of Regional Climate Change on Human Health. Patz, J. A., Campbell-Lendrum, D., Holloway, T., & Foley, J. A. 438(7066):310–317. Paper doi abstract bibtex The World Health Organisation estimates that the warming and precipitation trends due to anthropogenic climate change of the past 30~years already claim over 150,000 lives annually. Many prevalent human diseases are linked to climate fluctuations, from cardiovascular mortality and respiratory illnesses due to heatwaves, to altered transmission of infectious diseases and malnutrition from crop failures. Uncertainty remains in attributing the expansion or resurgence of diseases to climate change, owing to lack of long-term, high-quality data sets as well as the large influence of socio-economic factors and changes in immunity and drug resistance. Here we review the growing evidence that climate-health relationships pose increasing health risks under future projections of climate change and that the warming trend over recent decades has already contributed to increased morbidity and mortality in many regions of the world. Potentially vulnerable regions include the temperate latitudes, which are projected to warm disproportionately, the regions around the Pacific and Indian oceans that are currently subjected to large rainfall variability due to the El Niño/Southern Oscillation sub-Saharan Africa and sprawling cities where the urban heat island effect could intensify extreme climatic events.

Sensitivity of Managed Boreal Forests in Finland to Climate Change, with Implications for Adaptive Management. Kellomäki, S., Peltola, H., Nuutinen, T., Korhonen, K. T., & Strandman, H. 363(1501):2339–2349. Paper doi abstract bibtex This study investigated the sensitivity of managed boreal forests to climate change, with consequent needs to adapt the management to climate change. Model simulations representing the Finnish territory between 60 and 70°$\mkern1mu$N showed that climate change may substantially change the dynamics of managed boreal forests in northern Europe. This is especially probable at the northern and southern edges of this forest zone. In the north, forest growth may increase, but the special features of northern forests may be diminished. In the south, climate change may create a suboptimal environment for Norway spruce. Dominance of Scots pine may increase on less fertile sites currently occupied by Norway spruce. Birches may compete with Scots pine even in these sites and the dominance of birches may increase. These changes may reduce the total forest growth locally but, over the whole of Finland, total forest growth may increase by 44\,%, with an increase of 82\,% in the potential cutting drain. The choice of appropriate species and reduced rotation length may sustain the productivity of forest land under climate change.

Land Transport Systems under Climate Change: A Macroeconomic Assessment of Adaptation Measures for the Case of Austria. Bachner, G. . Paper abstract bibtex In the light of climate change, transport systems become increasingly stressed by extreme weather and gradual climatic changes, resulting in direct costs which arise in the affected sector as well as indirect costs due to economic spill-over effects. To attenuate these costs, sector specific adaptation measures are needed, raising the question of the net-benefits of adaptation at a macroeconomic level. However, despite their importance such assessments of impacts and adaptation at the macro-level are scarce and coarse in their implementation. This paper contributes to fill this research gap by analyzing specific adaptation measures for the land transport sectors. To reveal both direct and indirect effects of impacts and adaptation a computable general equilibrium model is deployed. Results confirm the importance of a macroeconomic framework since the indirect effects are found to be larger than the direct ones due to strong economic interlinkages with the transport system. Adaptation measures are able to reduce climate change induced GDP and welfare losses as well as unemployment; even though adaptation does not always seem economically reasonable at the business level.

Paper doi abstract bibtex Extreme vapor pressure deficits (VPD) have been associated with enhanced wildfire risk. Using one model, we found for 2015/16 that human influences quintupled the risk of extreme VPD for western North America and increased the risk for extratropical Australia. [Excerpt: Introduction] In 2016, about 3.6 million hectares of land burned in the United States and Canada (NIFC 2017; NFD 2017). In Canada, a wildfire southwest of Fort McMurray, Alberta, caused the largest wildfire evacuation in Alberta's history and destroyed 2400 homes in 2016 (McConnell 2016). Abatzoglou and Williams (2016; AP16 from hereon) showed that anthropogenic climate change has increased forest fire activity in the western United States. This raises the question if anthropogenic forcing are increasing the risk of devastating events outside this region such as the Canadian Fort McMurray fire. [] During the Australian summer of 2015/16, the country experienced high numbers of bushfires: the southwest and southeast of the country were most affected with more than 100 000 hectares of vegetation burned in Tasmania (ABC News 2016a). Over the course of this summer, 408 residential and 500 nonresidential buildings were destroyed nationwide. This fire season was moderately destructive with insured losses of about AUD \$350 million (ABC News 2016b). [] AP16 found for the western United States a strong link between the spring-summer vapor pressure deficit (VPD) and the annual burned area. In this paper, we build on this work using monthly average VPD as a proxy for fire risk during the summer of 2016 for extratropical Australia (October-February) and western North America (May-August) though this link has not been directly established for either region. VPD is an absolute measure of the state of atmospheric moisture, specifically the difference between the saturation vapor pressure and the actual vapor pressure of the atmosphere (Seagar et al. 2015).

Paper doi abstract bibtex Climate change can increase the risk of conditions that exceed human thermoregulatory capacity. Although numerous studies report increased mortality associated with extreme heat events, quantifying the global risk of heat-related mortality remains challenging due to a lack of comparable data on heat-related deaths. Here we conducted a global analysis of documented lethal heat events to identify the climatic conditions associated with human death and then quantified the current and projected occurrence of such deadly climatic conditions worldwide. We reviewed papers published between 1980 and 2014, and found 783 cases of excess human mortality associated with heat from 164 cities in 36 countries. Based on the climatic conditions of those lethal heat events, we identified a global threshold beyond which daily mean surface air temperature and relative humidity become deadly. Around 30\,% of the world's population is currently exposed to climatic conditions exceeding this deadly threshold for at least 20 days a year. By 2100, this percentage is projected to increase to ̃48\,% under a scenario with drastic reductions of greenhouse gas emissions and ̃74\,% under a scenario of growing emissions. An increasing threat to human life from excess heat now seems almost inevitable, but will be greatly aggravated if greenhouse gases are not considerably reduced.

Paper doi abstract bibtex Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense 2005 drought, a possible analog of future events. Affected forest lost biomass, reversing a large long-term carbon sink, with the greatest impacts observed where the dry season was unusually intense. Relative to pre-2005 conditions, forest subjected to a 100-millimeter increase in water deficit lost 5.3 megagrams of aboveground biomass of carbon per hectare. The drought had a total biomass carbon impact of 1.2 to 1.6 petagrams (1.2 × 1015 to 1.6 × 1015 grams). Amazon forests therefore appear vulnerable to increasing moisture stress, with the potential for large carbon losses to exert feedback on climate change.

Silver Fir Defoliation Likelihood Is Related to Negative Growth Trends and High Warming Sensitivity at Their Southernmost Distribution Limit. Linares, J. C. & Camarero, J. J. 2012:1–8. Paper doi abstract bibtex Changes in radial growth have been used to estimate tree decline probability since they may indicate tree responses to long- and short-term stressors. We used visual assessments of crown defoliation, an indicator of decline, and retrospective tree-ring analyses to determine whether climate-growth sensitivity and tree growth rates may be used as predictors of tree die-off probability in Abies alba (silver fir) at the Spanish Pyrenees. We used climatic data to calculate standardized temperature and precipitation data and drought indexes. Basal area increment was measured for declining (defoliation $>$ 50\,%) and nondeclining (defoliation $<$ 50\,%) silver firs in stands with contrasting defoliation. Logistic regressions were applied to predict tree die-off. Since the early 1980s, a synchronised reduction in basal area increment was observed in declining trees. The basal area increment trend correctly classified 64\,% of declining trees and 94\,% of nondeclining trees. The growth sensitivity to water deficit, temperature, and a drought index also significantly predicted silver fir decline, but providing underestimated predictions. Our findings underscore the idea that long-term climatic warming seems to be a major driver of growth decline in silver fir. Ongoing growth reduction and enhanced mortality may promote vegetation shifts in declining Pyrenean A. alba forests.

Is Robustness Really Robust? How Different Definitions of Robustness Impact Decision-Making under Climate Change. Giuliani, M. & Castelletti, A. 135(3-4):409–424. Paper doi abstract bibtex Robust decision-making is being increasingly used to support environmental resources decisions and policy analysis under changing climate and society. In this context, a robust decision is a decision that is as much as possible insensitive to a large degree of uncertainty and ensures certain performance across multiple plausible futures. Yet, the concept of robustness is neither unique nor static. Multiple robustness metrics, such as maximin, optimism-pessimism, max regret, have been proposed in the literature, reflecting diverse optimistic/pessimistic attitudes by the decision maker. Further, these attitudes can evolve in time as a response to sequences of favorable (or adverse) events, inducing possible dynamic changes in the robustness metrics. In this paper, we explore the impact of alternative definitions of robustness and their evolution in time for a case of water resources system management under changing climate. We study the decisions of the Lake Como operator, who is called to regulate the lake by balancing irrigation supply and flood control, under an ensemble of climate change scenarios. Results show a considerable variability in the system performance across multiple robustness metrics. In fact, the mis-definition of the actual decision maker's attitude biases the simulation of its future decisions and produces a general underestimation of the system performance. The analysis of the dynamic evolution of the decision maker's preferences further confirms the potentially strong impact of changing robustness definition on the decision-making outcomes. Climate change impact assessment studies should therefore include the definition of robustness among the uncertain parameters of the problem in order to analyze future human decisions under uncertainty.

Forest Fire Danger Projections in the Mediterranean Using ENSEMBLES Regional Climate Change Scenarios. Bedia, J., Herrera, S., Camia, A., Moreno, J. M., & Gutiérrez, J. M. 122(1-2):185–199. Paper doi abstract bibtex We present future fire danger scenarios for the countries bordering the Mediterranean areas of Europe and north Africa building on a multi-model ensemble of state-of-the-art regional climate projections from the EU-funded project ENSEMBLES. Fire danger is estimated using the Canadian Forest Fire Weather Index (FWI) System and a related set of indices. To overcome some of the limitations of ENSEMBLES data for their application on the FWI System – recently highlighted in a previous study by Herrera et al. (Clim Chang 118:827-840, 2013) – we used an optimal proxy variable combination. A robust assessment of future fire danger projections is undertaken by disentangling the climate change signal from the uncertainty derived from the multi-model ensemble, unveiling a positive signal of fire danger potential over large areas of the Mediterranean. The increase in the fire danger signal is accentuated towards the latest part of the transient period, thus pointing to an elevated fire potential in the region with time. The fire-climate links under present and future conditions are further discussed building upon observed climate data and burned area records along a representative climatic gradient within the study region.

Climate Change Might Drive the Invasive Tree Robinia Pseudacacia into Nature Reserves and Endangered Habitats. Kleinbauer, I., Dullinger, S., Peterseil, J., & Essl, F. 143(2):382–390. Paper doi abstract bibtex Static networks of nature reserves disregard the dynamics of species ranges in changing environments. In fact, climate warming has been shown to potentially drive endangered species out of reserves. Less attention has been paid to the related problem that a warmer climate may also foster the invasion of alien species into reserve networks. Here, we use niche-based predictive modelling to assess to which extent the Austrian Natura 2000 network and a number of habitat types of conservation value outside this network might be prone to climate warming driven changes in invasion risk by Robinia pseudacacia L., one of the most problematic alien plants in Europe. Results suggest that the area potentially invaded by R. pseudacacia will increase considerably under a warmer climate. Interestingly, invasion risk will grow at a higher than average rate for most of the studied habitat types but less than the national average in Natura 2000 sites. This result points to a potential bias in legal protection towards high mountain areas which largely will remain too cold for R. pseudacacia. In contrast, the selected habitat types are more frequent in montane or lower lying regions, where R. pseudacacia invasion risk will increase most pronouncedly. We conclude that management plans of nature reserves should incorporate global warming driven changes in invasion risk in a more explicit manner. In case of R. pseudacacia, reducing propagule pressure by avoiding purposeful plantation in the neighbourhood of reserves and endangered habitats is a simple but crucial measure to prevent further invasion under a warmer climate.

Integrated Modeling of Large Scale Forest Patterns and Connectivity of Protected Areas and Relevance in the Context of Ecosystem Services and Climate Change. Estreguil, C., Caudullo, G., de Rigo, D., Whitmore, C., & San-Miguel-Ayanz, J. In FORECOM: Forest Cover Changes in Mountainous Regions - Drivers, Trajectories and Implications. Institute of Geography and Spatial Management of the Jagiellonian University. Paper abstract bibtex The mitigation of ecosystem fragmentation is important in Target 2 of the new European Biodiversity strategy to 2020, aiming at the maintenance and enhancement of ecosystem services (e.g. habitat provision, disturbance regulation, climate change mitigation). Better knowledge on patterns, fragmentation processes and functional connectivity of focal ecosystem is needed within and between protected areas as well as in the wider country side. An overview of JRC activities is given on tools, models and applications for a European-wide improved and harmonised reporting on forest patterns and connectivity (fragmentation). The recently available generic, reproducible and integrated characterisation of patterns based on three models and a set of indices is presented. National profiles of forest pattern in the wider country side are shown on forest morphological shapes, fragmentation landscape pattern, edge interfaces and connectivity. The connectivity of Natura2000 forest sites is then computed in few countries (Spain, Belgium, Germany and Poland), and results allow for comparison of the connectivity index value across countries and the identification of key-sites and gaps in connectivity. The presentation finally introduces the dedicated pattern web map viewer which is now available from the European Forest Data Centre (EFDAC) for data viewing and query.

abstract = {The mitigation of ecosystem fragmentation is important in Target 2 of the new European Biodiversity strategy to 2020, aiming at the maintenance and enhancement of ecosystem services (e.g. habitat provision, disturbance regulation, climate change mitigation). Better knowledge on patterns, fragmentation processes and functional connectivity of focal ecosystem is needed within and between protected areas as well as in the wider country side. An overview of JRC activities is given on tools, models and applications for a European-wide improved and harmonised reporting on forest patterns and connectivity (fragmentation). The recently available generic, reproducible and integrated characterisation of patterns based on three models and a set of indices is presented. National profiles of forest pattern in the wider country side are shown on forest morphological shapes, fragmentation landscape pattern, edge interfaces and connectivity. The connectivity of Natura2000 forest sites is then computed in few countries (Spain, Belgium, Germany and Poland), and results allow for comparison of the connectivity index value across countries and the identification of key-sites and gaps in connectivity. The presentation finally introduces the dedicated pattern web map viewer which is now available from the European Forest Data Centre (EFDAC) for data viewing and query.},

Spatial Patterns of European Droughts under a Moderate Emission Scenario. Spinoni, J., Naumann, G., & Vogt, J. 12:179–186. Paper doi abstract bibtex Meteorological drought is generally defined as a prolonged deficiency of precipitation and is considered one of the most relevant natural hazards as the related impacts can involve many different sectors. In this study, we investigated the spatial patterns of European droughts for the periods 1981-2010, 2041-2070, and 2071-2100, focusing on the projections under a moderate emissions scenario. To do that, we used the outputs of the KNMI-RACMO2 model, which belongs to the A1B family and whose spatial resolution is 0.25° × 0.25°. By means of monthly precipitation and potential evapotranspiration (PET), we computed the Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI) at the 12-month accumulation scale. Thereafter, we separately obtained drought frequency, duration, severity, and intensity for the whole of Europe, excluding Iceland. According to both indicators, the spatial drought patterns are projected to follow what recently characterized Europe: southern Europe, who experienced many severe drought events in the last decades, is likely to be involved by longer, more frequent, severe, and intense droughts in the near future (2041-2070) and even more in the far future (2071-2100). This tendency is more evident using the SPEI, which also depends on temperature and consequently reflects the expected warming that will be highest for the Mediterranean area in Europe. On the other side, less severe and fewer drought events are likely to occur in northern Europe. This tendency is more evident using the SPI, because the precipitation increase is projected to outbalance the temperature (and PET) rise in particular in Scandinavia. Regarding the mid-latitudes, the SPEI-based analyses point at more frequent drought events, while the SPI-based ones point at less frequent events in these regions. [Excerpt: Conclusions] In this study we investigated the tendency of drought events in Europe until 2100 under a moderate emissions scenario, the KNMI-RACMO2. To do that, we based our analyses on two drought indicators, the SPI and the SPEI, computed at a 12-month scale. Regarding the drought events, we defined four quantities (frequency, duration, severity, and intensity), and we compared the recent past (1981-2010) vs. the near (2041-2070) and the far future (2071-2100). The spatial drought patterns have been analyzed both at 0.25° × 0.25° and at the country scale. We looked for the answers to a few questions: are the drought events likely to become more frequent in the future? Will they be longer? Will they be more severe and intense? Southern Europe, that already experienced a drying trend in the second part of the 20th century (see, e.g. IPCC, 2014), is projected to be affected by more frequent, severe, intense, and longer drought events in the near future and even more in the far future. The drying trend is driven by the combination of PET increase and precipitation decrease. Oppositely, northern Europe, the area that experienced a trend toward wetness from the 1970s onwards (IPCC, 2014), is projected to be involved by fewer and less intense droughts, mainly due to the projected precipitation increase. The results of this study should be considered as a preliminary step towards more detailed analyses regarding the projections of European drought events. Many different aspects could be introduced to refine the methodologies and the outputs. Among them we plan to study seasonal droughts, adding new indicators, using other models belonging to the A1B (see Meehl et al., 2005, for a summary) and different scenario families, performing tests to compute the statistical error intervals of the climate projections, and coupling the drought information with other climate extremes.

Relationship between Forest Density and Albedo in the Boreal Zone. Lukeš, P., Stenberg, P., & Rautiainen, M. 261-262:74–79.

In this study, we identified factors driving boreal forest albedo using a theoretical model. We show that species-specific stand albedos and their diurnal courses are tightly linked to forest density. The albedos differed significantly between species with the lowest values being observed for spruce and the highest for birch. From the forest management perspective, our results suggest that an increase in albedo can be achieved by (1) increasing the proportion of birch in conifer-dominated forests and (2) managing forests to have a low stand density throughout the rotation period.

Potential Effects of Climate Change on Insect Herbivores in European Forests - General Aspects and the Pine Processionary Moth as Specific Example. Netherer, S. & Schopf, A. 259(4):831–838. Paper doi abstract bibtex The nature of ” climate change” will differ with geographical regions and its final impact on ecosystems vary with the extent of temperature increase, changes in irradiance and levels of UVB, amount and patterns of precipitation and humidity, and alterations in the incidence and nature of abiotic disturbances. Despite many uncertainties, there is consensus in the fact that global warming already has and will have impact on the temporal and spatial dynamics of insect herbivores. Ectothermic organisms are affected by the changes in environmental conditions directly in dispersal, reproduction, development and mortality, and indirectly through altered plant nutritional quality, resistance and via community interactions. Ambiguous consequences are to be expected depending on the individual host plant and herbivore species, probably involving altered incidence and intensity of pest outbreaks and changes in distributional ranges. Regions that represent northern or upper limits of occurrence, such as the Alps or the boreal zone, are likely to be affected most by an increase in stability and population density of certain pest species, such as defoliating insects or bark beetles. At the same time, temperature increase and drought will render areas of distribution in southern and continental parts of Europe less suitable for heat susceptible species, which will probably not only result in northwards shifts, but range contractions. The review is based on chapters of the ” Study on impacts of climate change on European forests and options for adaptation” led by the European Forest Institute (Efi) and on results of the EU project ” PROMOTH - Global change and pine processionary moth: a new challenge for integrated pest management”. Thaumetopoea pityocampa serves as illustrative example for insect herbivores whose latitudinal and altitudinal distribution is mainly controlled by temperature and already modified by global warming.
