Climate change played a major role in extreme 2016 Arctic heat wave

This article discusses the impact climate change is having on the Arctic.

Just days before Christmas in 2016, the North Pole was 50 degrees above its usual winter temperature. The top of the world was just above freezing.

Unusually warm air had smothered the Arctic throughout that year, and now a recently published report, led by government scientists at the National Oceanic and Atmospheric Administration (NOAA), found that it’s nearly impossible to explain the intensity of this warmth simply by normal fluctuations in weather.

A heating event like this isn’t natural, they argue — it’s largely human-induced, specifically by the greenhouse gases emitted by human industry and trapped in the atmosphere.
