As a rule, heat waves are related to unusual jet stream patterns, and the Siberian heat wave is no different.

Arctic heat waves are happening more often Arctic heat waves now arrive on top of an already warmer planet, so they’re more frequent than they used to be.

As director of the National Snow and Ice Data Center and an Arctic climate scientist who first set foot in the far North in 1982, I’ve had a front-row seat to watch the transformation.

As long ago as the 1890s, scientists predicted that increasing levels of carbon dioxide in the atmosphere would lead to a warming planet, particularly in the Arctic, where the loss of reflective snow and sea ice would further warm the region.

We do know that we’re seeing significant effects from this heat wave, particularly in the early loss of sea ice.
