IPCC: major climate changes are inevitable and irreversible

 The AR6 Climate Change 2021: The Physical Science Basis, is a result of eight years of hard work of hundreds of experts and peer-review studies. It represents the world’s full knowledge to date of the physical basis of climate change and found that human activity was “unequivocally” the cause of rapid changes to the climate, including sea level rises, melting polar ice and glaciers, heatwaves, floods, and droughts.

Human influence has warmed the climate at a rate unprecedented in at least the past 2000 years


Global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep reductions in carbon dioxide (CO2) and other greenhouse gas emissions occur in the coming decades.

Only fast and radical reductions in greenhouse gases in this decade can prevent such climate breakdown, with every fraction of a degree of further heating likely to compound the accelerating effects.
