Australia researchers said rising sea levels have wiped out a rodent that lived on the Great Coral Reef. The Bramble Cay melomys was so called because it lived on Bramble Cay, an atoll on the northern part of the reef. The seawater destroyed the animal's habitat and food source. So this destruction of species has begun and will until we do something about it – and "we" doesn't include capitalists who pussyfoot around with their treaties which, as the most, slow it down.
Each group of politicians is responsible to the capitalist class of their countries, all of which want the maintenance (an ironic word) of capitalism because it simply means profit.
Only an economic system which doesn't contain the profit system can stop and reverse the effects of global warming.
