Intergovernmental bodies and the draft UN expert report on climate stress that "the worst is to come, and it will affect the lives of our children and grandchildren more than it does ours."
The draft UN expert report on climate warns of "irreversible consequences for human and ecological systems" if warming permanently exceeds 1.5 degrees Celsius.
The technical summary, located on 137 pages of this report, stressed that "life on Earth can recover from major climate change by moving to new species and establishing new ecosystems." "As for humanity, it is not capable of that," he added.
And 204 million people will be exposed to "extreme heat waves" if the warming exceeds two degrees Celsius instead of one and a half degrees, according to the report obtained by AFP exclusively.
The full 4,000-page assessment report, which is much more pessimistic than the previous report issued in 2014, is dedicated to providing information for policy decisions.
But the report will not be published until February 2022, after the 195 member states of the United Nations have unanimously approved it.
Some scientists consider that too late for the important international meetings on climate and biodiversity that will take place in late 2021.
