Protected areas (PAs) are essential to biodiversity conservation, but their static boundaries may undermine their potential for protecting species under climate change. We assessed how the climatic conditions within global terrestrial PAs may change over time. By 2070, protection is expected to decline in cold and warm climates and increase in cool and hot climates over a wide range of precipitation. Most countries are expected to fail to protect >90% of their available climate at current levels. The evenness of climatic representation under protection—not the amount of area protected—positively influenced the retention of climatic conditions under protection. On average, protection retention would increase by ~118% if countries doubled their climatic representativeness under protection or by ~102% if countries collectively reduced emissions in accordance with global targets. Therefore, alongside adoption of mitigation policies, adaptation policies that improve the complementarity of climatic conditions within PAs will help countries safeguard biodiversity.

Over Time

Assumptions that local communities have an endogenous capacity to adapt to climate change stemming from time-tested knowledge and an inherent sense of community that prompts mobilisation are becoming increasingly common in material produced by international organisations. This discourse, which relies on ahistorical and apolitical conceptions of localities and populations, is based on ideas of timeless knowledge and places. Analysing the water-place nexus in Ladakh, in the Indian Himalayas, through a close study of glacier practices as they change over time, the article argues that local knowledge is subject to change and must be analysed in light of changing conceptions and experiences of place by the state and by local populations alike.

ABSTRACTClimate change modifies ecosystem processes directly through its effect on environmental conditions, but also indirectly by changing community composition. Theoretical studies and grassland experiments suggest that diversity may increase and stabilize communities’ productivity over time. Few recent studies on forest ecosystems suggested the same pattern but with a larger variability between the results. In this paper, we aimed to test stabilizing diversity effect for two kinds of mixtures (Fagus sylvatica - Quercus pubescens and Fagus sylvatica - Abies alba), and to assess how climate may affect the patterns. We used tree ring data from forest plots distributed along a latitudinal gradient across French Alps. We found that diversity effect on stability in productivity varies with stand composition. Most beech–fir stands showed a greater stability in productivity over time than monocultures, while beech–oak stands showed a less stable productivity. Considering non-additive effects, no significant trends were found, regardless the type of mixed stands considered. We further highlighted that these patterns could be partially explained by asynchrony between species responses to annual climatic conditions (notably to variation in temperature or precipitation), overyielding, and climatic conditions. We also showed that the intensity of the diversity effect on stability varies along the ecological gradient, consistently with the stress gradient hypothesis for beech-oak forests, but not for beech-fir forests. This study showed the importance of the species identity on the relationships between diversity, climate and stability of forest productivity. Better depicting diversity and composition effects on forest ecosystem functioning appears to be crucial for forest managers to promote forest adaptation and maintain timber resource in the context of on-going climate change.

AbstractSeveral studies have documented a global pattern of phenological advancement that is consistent with ongoing climate change. However, the magnitude of these phenological shifts is highly variable across taxa and locations. This variability of phenological responses has been difficult to explain mechanistically. To examine how the evolution of multi-trait cueing strategies could produce variable responses to climate change, we constructed a model in which organisms evolve strategies that integrate multiple environmental cues to inform anticipatory phenological decisions. We simulated the evolution of phenological cueing strategies in multiple environments, using historic climate data from 78 locations in North America and Hawaii to capture features of climatic correlation structures in the real world. Organisms in our model evolved diverse strategies that were spatially autocorrelated across locations on a continental scale, showing that similar strategies tend to evolve in similar climates. Within locations, organisms often evolved a wide range of strategies that showed similar response phenotypes and fitness outcomes under historical conditions. However, these strategies responded differently to novel climatic conditions, with variable fitness consequences. Our model shows how the evolution of phenological cueing strategies can explain observed variation in phenological shifts and unexpected responses to climate change.

Protected areas are considered the cornerstone of biodiversity conservation, but face multiple problems in delivering this core objective. The growing trend of framing biodiversity and protected area values in terms of ecosystem services and human well-being may not always lead to biodiversity conservation. Although globalization is often spoken about in terms of its adverse effects to the environment and biodiversity, it also heralds unprecedented and previously inaccessible opportunities linked to ecosystem services. Biodiversity and related ecosystem services are amongst the common goods hardest hit by globalization. Yet, interconnectedness between people, institutions, and governments offers a great chance for globalization to play a role in ameliorating some of the negative impacts. Employing a polycentric governance approach to overcome the free-rider problem of unsustainable use of common goods, we argue here that REDD+, the United Nations Framework Convention on Climate Change (UNFCCC) climate change mitigation scheme, could be harnessed to boost biodiversity conservation in the face of increasing globalization, both within classic and novel protected areas. We believe this offers a timely example of how an increasingly globalized world connects hitherto isolated peoples, with the ability to channel feelings and forces for biodiversity conservation. Through the global voluntary carbon market, REDD+ can enable and empower, on the one hand, rural communities in developing countries contribute to mitigation of a global problem, and on the other, individuals or societies in the West to help save species they may never see, yet feel emotionally connected to.

Abstract Key message We developed a climatic response function using 20-year tree height observed from 45Ginkgo bilobaplantations in China and used it to predict the growth and habitat responses to anticipated climate change. We projected northward and upward shifts in the species habitat and productive areas, but a dramatic contraction of the species distribution is unlikely to occur at least during the present century. Context Ginkgo biloba is the only living species in the division Ginkgophyta. The species exists in small natural populations in southeastern China but is cultivated across China and the world. The species’ future under climate change is of concern. Aims This study was initiated to model the species’ growth response to climate change and to predict its range of suitable habitat under future climates. Methods Using height data from 45 20 years old plantations growing under a wide range of climatic conditions across China, we developed univariate and bivariate climatic response functions to identify the climate requirements of the species. Results According to the amount of variance explained (> 70%) and the high level of agreement (> 99%) with independent species occurrence coordinates, the developed climate response function was highly accurate and credible. Projections for future periods (2011–2040, 2041–2070, and 2071–2100) under the Representative Concentration Pathway 4.5 (RCP4.5) scenario indicated that the areas of potential suitable habitat would increase (25–67 million hectares). It would also be associated with northward (0.21–0.62° in latitude) and elevational (24–75 m) shifts. Conclusion Global climate change is projected to increase the area of potential suitable habitats for Ginkgo and shift its spatial distributions northward and upward.

The Future

Buildings and homes in Canada will be exposed to unprecedented climatic conditions in the future as a consequence of global climate change. To improve the climate resiliency of existing and new buildings, it is important to evaluate their performance over current and projected future climates. Hygrothermal and whole building simulation models, which are important tools for assessing performance, require continuous climate records at high temporal frequencies of a wide range of climate variables for input into the kinds of models that relate to solar radiation, cloud-cover, wind, humidity, rainfall, temperature, and snow-cover. In this study, climate data that can be used to assess the performance of building envelopes under current and projected future climates, concurrent with 2 °C and 3.5 °C increases in global temperatures, are generated for 11 major Canadian cities. The datasets capture the internal variability of the climate as they are comprised of 15 realizations of the future climate generated by dynamically downscaling future projections from the CanESM2 global climate model and thereafter bias-corrected with reference to observations. An assessment of the bias-corrected projections suggests, as a consequence of global warming, future increases in the temperatures and precipitation, and decreases in the snow-cover and wind-speed for all cities.

Mitigation Policies

A wide range of climate change mitigation policies have been developed around the world and these policies have become one of the major concerns, however there is still debate among scientists about what are the main external benefits and how to account for them and prepare effective climate change mitigation policies that might be widely accepted by society in general. One of the main ways to assess external benefit of climate change mitigation in energy sector is to conduct Willingness to Pay (WTP) assessments for climate change mitigation options by households. There are many studies on WTP assessment for climate stability conducted in recent years. The paper surveys the existing literature on WTP for climate change mitigation policy in the energy sector. The aim of the paper is to identify the common variables across a varied set of WTP studies in order to establish a basis for comparison. The key variables selected for analysis of WTP studies for climate change mitigation in energy sector addressed in the paper are: the WTP assessment methods; the main attributes used for comparing alternatives in WTP studies, targeted climate change mitigation policies in energy sector, mathematical model used to estimate WTP, the main socio-demographic factors having impact on WTP for climate change mitigation policies. The analysis of WTP studies for climate change mitigation is grouped in two areas: renewables and energy efficiency measures in households. The paper provides analytical structure for future studies to evaluate the effects of variation in key comparative elements upon WTP.

The Impact

AbstractClimate change will have a profound effect on vine growing worldwide. Wine quality will also be affected, which will raise economic issues. Possible adaptations may result from changes in plant material, viticultural techniques, and the wine-making process. Relocation of vineyards to cooler areas and increased irrigation are other options, but they may result in potential conflicts for land and water use. Grapes are currently grown in many regions around the world, and growers have adapted their practices to the wide range of climatic conditions that can be found among or inside these areas. This knowledge is precious for identifying potential adaptations to climate change. Because climate change affects all activities linked to wine production (grape growing, wine making, wine economics, and environmental issues), multidisciplinary research is needed to guide growers to continue to produce high-quality wines in an economical and environmentally sustainable way. An example of such an interdisciplinary study is the French LACCAVE (long-term adaptation to climate change in viticulture and enology) project, in which researchers from 23 institutes work together on all issues related to the impact of climate change on wine production.
