Key Arctic Indicators Show Big Changes

April 4, 2019

Very nice overview of Arctic changes in past several decades, graphs worth bookmarking.

    Excellent summary, and the graphs ARE worth saving. Looking at this makes one wonder why there are still any deniers.

  2. Keith McClary Says:

    The Banks Island thaw slumps are shocking.

    “In 1984, there were about 60 active thaw slumps on the island. In 2013, there were more than 4,000”

      Beyond shocking. How many thousands of “little” climate change-induced occurrences like this are happening all over the globe that no one but the locals are even aware of?

        Meanwhile, even big climatic changes might not be noticed by urbanites and suburbanites because they’re masked by human environment changes (new billboards, facades, skyscrapers disrupting the wind, traffic, construction, etc.). Vague shifts in temperatures and precip are less noticeable than, say, the sudden appearance of power-scooters (and power-scooter users).

        We who are comfortably separated from nature would be the last to know (unless we made a point of paying attention to it).

    While weather is not the same as climate, Alaska had a very weird March this year.

    New monthly high temperature records were set in 10 of the selected 19 stations, especially in the Interior and in western and northern Alaska. Kotzebue’s average monthly temperature was 21.9 degrees Fahrenheit above normal.

      Two good finds, Bob. Scientists have been saying for years that Arctic is THE place to watch because it’s warming faster than any other region of the planet. Many of us on Crock have said the same thing—-in fact,that may have been one of the first comments I ever made here years ago (CRS).

      All these papers, studies, and anecdotal reports just add more fuel to the fire (or is that a not-so-funny way to say it), but don’t forget that Antarctica is acting up, and we almost totally ignore the warming at the Third Pole (where more than a billion people live and CAGW will heavily impact more than double that number).

      Too many monsters under the bed—how do we manage to sleep?
