In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling. And yes, also the increase in back-radiation towards the Earth surface from the CO2 greenhouse effect is a measured fact. It’s not hard to understand.

Last week, the Nobel physics prize was (half) awarded to Suki Manabe and Klaus Hasselmann for their work on climate prediction and the detection and attribution of climate change. This came as quite a surprise to the climate community – though it was welcomed warmly. But let’s go back to the beginning.

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!) 1981) which can be seen here.
