[latexpage] A new paper from Scafetta and it's almost as bad as the last one. Back in March, we outlined how a model-observations comparison paper in GRL by Nicola Scafetta () got wrong basically everything that one could get wrong (the uncertainty in the observations, the internal variability in the models, the statistical basis for comparisons - the lot!).

Watching the detections
By Gavin 28 Comments
The detection and the attribution of climate change are based on fundamentally different frameworks and shouldn't be conflated.

New misguided interpretations of the greenhouse effect from William Kininmonth

With the signing of the Inflation Reduction Act (IRA) on Tuesday Aug 16, the most significant climate legislation in US federal history (so far) became law.
