Climate Change is real and impacting the arctic

Recent warming has been unprecedented in speed, scale, and cause. Last year, we reported on a study that found the rate of warming since 1900 is 50 times greater than the rate of cooling in the previous 5000 years, which threatens to destroy the stable climate that enabled civilization.
The warming is so fast that it’s easy to forget how cold it used to be just a few decades ago, which is the point of a recent Climate Central analysis and the awesome xkcd cartoon based on it (above).
We’ve known for a while that the Arctic — which is warming at twice the rate of Earth as a whole — is now warmer than it has been in at least 2000 years. As a National Center for Atmospheric Research study found in 2009:
