Weatherunderground has a new web page that lets you view extreme weather of various types (that you can select) in a specified timeframe: Weather extremes. This is very cool, as shows very visually how many records are being broken in recent years.
I'm risking the diary police with this poor excuse for one, but I thought people would find this tool useful. Weather underground (and Jeff Masters) have done a lot to try to raise awareness of climate change, and should be commended. (And after a long wait, they have a pretty good phone app too, at least fo iPhone.)
