Almost two thirds of common plants and half the animals could see a dramatic decline this century due to climate change according to research from the University of East Anglia.
Research published today in the journal Nature Climate Change looked at 50,000 globally widespread and common species and found that two thirds of the plants and half of the animals will lose more than half of their climatic range by 2080 if nothing is done to reduce the amount of global warming and slow it down.
This means that geographic ranges of common plants and animals will shrink globally and biodiversity will decline almost everywhere.
Plants, reptiles and particularly amphibians are expected to be at highest risk. Sub-Saharan Africa, Central America, Amazonia and Australia would lose the most species of plants and animals. And a major loss of plant species is projected for North Africa, Central Asia and South-eastern Europe.
But acting quickly to mitigate climate change could reduce losses by 60 per cent and buy an additional 40 years for species to adapt. This is because this mitigation would slow and then stop global temperatures from rising by more than two degrees Celsius relative to pre-industrial times (1765). Without this mitigation, global temperatures could rise by 4 degrees Celsius by 2100.
The study was led by Dr Rachel Warren from UEA's school of Environmental Sciences and the Tyndall Centre for Climate Change Research. Collaborators include Dr.Jeremy VanDerWal at James Cook University in Australia and Dr Jeff Price, also at UEA's school of Environmental Sciences and the Tyndall Centre. The research was funded by the Natural Environment Research Council (NERC).
Dr Warren said: "While there has been much research on the effect of climate change on rare and endangered species, little has been known about how an increase in global temperature will affect more common species.
"This broader issue of
