Alaskan Climate Change

“Well, as the nation’s only Arctic state and being the governor of that state, Alaska feels and sees impacts of climate change more so than any other state. And we know that it’s real.” -Palin during the VP debate.

Here’s a graph of sea surface temperatures around Alaska:

It is apparent that the great climate shift of 1978 caused a step change in ocean temperatures, though there has been no trend in temperatures since.

Here’s data from several temperature stations in Alaska.

Aside from a few surface stations, climate change in Alaska seems to have been on hold for the past thirty years.

    Where/which dataset are you getting the graphs from?

    Sorry, forgot to post that. The SST data is te Smith Reynolds data from NOAA. For instructions to extract the SST data, see my post: https://climatechangeskeptic.wordpress.com/2008/07/09/comparing-noaa-sst-data-to-uah-and-rss/

    The surface stations can be located using this GISS page:

    Any way to see the raw surface station data before it goes through the GHCN and GISTemp manipulations?

    Maybe, but I’m not the guy to talk to. Email Anthony Watts or ask on his blog.
    You’ve got to look for the raw USHCN data; that’s where GISS gets it’s US data from. I don’t know why GHCN would mess with US network data, but I’m leaving my climate comfort zone now so I could be wrong.
    And just for the hell of it:
