Climate change will triple the impacts on the “living areas” of the world


A new study from the Wildlife Conservation Society (WCS) and multiple partners who modeled changes in the 45 different ‘living zones’ of the world from climate change have revealed that climate impacts could soon triple in these areas if the earth continues to decline. ’emit “activities as usual”.

Living zones are distinct biogeographical regions characterized by biotemperature, precipitation, and aridity representing large-scale ecosystem types.

The study found that the living zones of the world have already changed from the early 1900s to the present day in all biomes, including boreal forests, temperate coniferous forests, and tropical coniferous forests. This includes impacts on 27 million square kilometers (10.4 million square miles) or 18.3 percent of the earth. The boundaries between life zones have shifted towards the poles and to higher altitudes, leading to expansions of areas associated with equatorial climates and contractions of areas associated with temperate climates.

Anticipated future changes are expected to accelerate rapidly, especially if the world does not act to reduce emissions. This includes the potential impacts on a potential additional 62 million square kilometers (24 million square miles) or 42.6 percent of the earth’s land under the status quo.

Living areas associated with subpolar rainfed tundra, humid tundra and humid tundra are expected to experience the greatest decreases, while tropical rainforest, tropical rainforest, and cold temperate humid forest are expected to experience the greatest increases. more important. Boreal and polar latitudes are expected to experience substantial area losses, although their vast extent will help offset some of these expected losses.

According to Dr Paul Elsen, WCS Climate Adaptation Scientist and lead author of the study: “The likely future changes in the living areas of the world are likely to have a substantial impact on people’s livelihoods and biodiversity. . Large areas of the world are getting hotter and drier and this is already having an impact on the living areas of the earth.

Dr Hedley Grantham, WCS Director of Conservation Planning and co-author of the study, said: “COP26 is our best chance for countries to commit to reducing emissions and put us on a best future path for climate change and its impacts.
