"Climate change could drive up to a sixth of animals and plants on Earth to extinction unless governments cut rising greenhouse gas emissions, according to a U.S. study published on Thursday.
Species in South America, Australia and New Zealand are most at risk, since many live in small areas or cannot easily move away to adapt to heatwaves, droughts, floods or rising seas, said the report in the journal Science.
The study averaged out 131 previous studies of climate change, whose projections of the number of species that could be lost to climate change ranged from zero to 54 percent of species worldwide - too wide to be useful in designing conservation policies."
