There are just a few problems with the reporting on the IPCC report. First off, the actual headline should have been that the IPCC had revised downward its estimate of impending doom since the IPCCs AR5 report in 2014: according to the report itself, scientists agree that the remaining carbon budget for 1.5 degrees Celsius or 2 degrees Celsiuswould be larger than the estimates at the time of the AR5.

Then theres the question of how much damage will actually be done. While the report states with high confidence that more environmental damage will occur at 2 degrees Celsius than 1.5 degrees Celsius, the report is far less confident about the specific damage that will occur by 2040. And the predicted damage isnt actually catastrophic. Species loss and coral reef bleaching are certainly bad things. But theres no actual prediction of mass death or hellfire.
