Heavy loss of species due to climate change

Heavy loss of species due to climate change

Studies found that if temperature is to rise by 2°C since pre-industrial times, global extinction risk will rise from 2.8% today to 5.2%.

At the current pace of carbon emissions, a rise of 4°C will lead to an extinction rate of 16% that is 1 in 6.

Populations of vertebrate species have halved since 1970 (WWF-UK’s Living Planet Report).
Amphibians face a number of threats to their survival

Many species will adapt to climate change by shifting their ranges but others will not either because their habitat has disappeared or because they cannot reach their habitat anymore.
Higher extinction risks are predicted for Australia, New Zealand and South America, where there are many species adapted to live in habitats not found elsewhere. In South America, the extinction risk was estimated to be 23%,

Unfortunately, this higher number projected might better reflect the number of species that might go extinct due to climate change globally.
Global extinction risk from climate change might be even higher than 16%, if we consider how the world's species are distributed, given that the majority of studies analysed were from Europe and North America, where extinction risks are lower.
