The findings support the view that the earth is currently experiencing a global mass extinction where the rate at which species are being lost is many times greater than the historical extinction rate. It is the sixth great mass extinction in the history of life on earth. Scientists said that previous predictions of how fast species are being lost because of climate change match the actual observed losses. They calculate that around 10 per cent of species alive today could be facing extinction by 2100.
Ilya Maclean and Robert Wilson, of the University of Exeter, examined nearly 200 previous predictions about how climate change may affect the extinction of species and compared them with about 130 reports of changes already observed.
The aim was to judge the accuracy of estimates made by scientists in the past about climate change predictions in relation to species extinction. They concluded that the observed threats matched well with the actual threats, based on real observations.
"We tried to see whether predictions were backed up by things that have already happened and this was what we found," Dr Maclean said. Read the full report here.
