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. Figure 1: Map of observed near-surface air temperature changes since the late 19 th Century. It’s not hard to understand. Gray areas show lack of data.

Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.

Presumably Dagsvik and Moen are used to this kind of model, but they seem to be inexperienced with the models used for weather and climate, which on the other hand are based on the laws of physics. Furthermore, the volume of the oceans increases from the melting of land ice.

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!) Figure SPM 8.

Climate scientists at the Union of Concerned Scientists (UCS) have dubbed the six-month stretch from May through October the “ Danger Season.” Not only has much of what climate scientists have been warning about come to pass, many of the extreme weather events the planet is now experiencing are worse than they expected. “To

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Several floating ice shelves – the massive slabs of ice that push back grounded ice from flowing into the ocean – have catastrophically broken up in a matter of days because of such melting.
