climate variation over time

The fabulous Watt’s Up With That ran a series of charts a few days ago showing temperature variation over time in Greenland ice cores. And by “over time” I mean going back over 400,000 years.

I thought it would make a cracking animation, with the fades and the arrows and the background music. But WordPress doesn’t play nice with Flash (which, in any case, is on my desktop machine in semi-exile). So I thought I’d do a simple Javascript dingus where you could click the picture to see the next one. Turns out, WordPress plays even less well with Javascript. Finally, in despair, I cut together a badly-paced lame-o animated .gif file that sucks ALL KINDS of ass.

Eh. Sorry. I really need to uncrate some of my old, professional tools and build some spiffier visuals. Reload the page to rewind.

Anyhow, do go read the article in the original Geek (not all the increments are in my retardimation). When he zooms all the way back to the longest view, it’s obvious that the earth’s most comfortable resting place is deep, deep cold. The last ten thousand years — you know, the period when our species crawled out of the muck and flourished — have all been much, MUCH warmer than the preceding umpty-ump hundreds of thousands.

And the 20th Century doesn’t come close to being the warmest of the warm.
