Arctic Ice Trends Sharply Downward: Few Notice or Care

It's frankly shocking to me how many people I encounter who still cling to the idea that the globe is not warming, despite vast scientific libraries of evidence to the contrary.

Here's the latest example, from data compiled by NASA and ICESAT:

Two take-away points from the chart above. One, the red indicates multi-year ice; two, the blue reveals thin seasonal ice, which will return in the winters…but has little of the density or the staying power of what has been lost. In the words of Ron Kwok, writing for the GRL:

The total area covered by the thicker, older "multi-year" ice that
has survived one or more summers shrank by 42 percent.

Which raises the question: What will it take to convince doubters? The loss of Miami?
