At present, about 2.8% of the species on Earth are at risk of extinction due to climate change and global
warming at 0.8degred celcius that has already occurred, Urban says. If the global average temperature
rises and then holds at 2°C above the preindustrial average (a level that many scientists think is no longer
achievable in view of estimates of future greenhouse gas emissions), then 5.2% might eventually die out. If
global temperatures eventually top out at 4.3°C above preindustrial levels, as some studies suggest they
will, climate change may ultimately claim one species out of every six.
