I’ve been studying how temperature has changed over the years in the Arctic. The longest record I’ve got is for land areas only, from the Berkeley Earth Surface Temperature project, which starts way back in 1750:
Admittedly, the earlier data are less precise (and less reliable), mainly because there’s so much less of it. Complete coverage of the Arctic (land areas) doesn’t kick in until about 1900. Still, this is what the Berkeley team came up with for the Arctic (which I’m defining as latitudes from 60°N to the pole).
I’ve been studying other records too, and may soon have more to report on Arctic temperature change. But for the moment, I just wanted to share the above graph with you.
Because that’s one hell of a hockey stick.
