Arctic Warming, 1958 vs 2018

Here's a nice comparison of Arctic warming -- north of 80 deg north latitude -- comparing 1958's average temperature to 2018's. (Source.) The warming is obvious, and stark.

PS: The summers aren't warming because when the temperature gets above 0°C, the extra energy goes first into melting ice, and only after in raising the air temperature. (Recall the phase diagram for water.)
