Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below).

Circle of Blue

Meltwater from Greenland’s ice sheets have caused about a quarter of the rise in the world’s sea levels. This week, Circle of Blue looks at a major new climate report, which finds that a warming planet is accelerating the water cycle. Just as human behavior causes atmospheric warming, it can also prevent it.

AR6 of the best

Real Climate

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!)
