Climate Audit - by Steve McIntyre » North versus South

July 2008 RSS numbers are out (as a poster mentioned). I expect MSU tomorrow and will post them up together. When I plotted up NH and SH sea ice, I thought that it would be interesting to plot the difference between N and S extratropics (20-80N versus 20-70S) - I plotted RSS TLT3 (through July 2008) as I had the file open. Here are the results, which I find pretty interesting. In general terms, the relative warming of the NH relative to the SH is something that we’re aware of, but isn’t the strength of the trend in the 30 years of satellite record astonishing? And this is nothing to do with UHI.

We’re talking 0.75 deg C in 30 years here!
