The Storms of Arctic Warming: Polar Amplification, Vortex Disruption to Set off Extreme Weather Events For US, UK Yet Again

robertscribbler

It’s happening again.

A story that starts in the Arctic where abnormally warm temperatures for this time of year are in the process of disrupting the polar vortex, shoving its node out of the Arctic Ocean and pushing it all the way south over Hudson and Baffin Bay. The result is a core of extreme cold shoved much closer to related warmer, southerly regions. A highly unstable event that is likely to spawn extreme weather for the US and UK yet again.

This polar heat amplification and related extreme weather is a signature of human-caused global warming. And though it wears a grotesque mask of what some would call a normal Arctic oscillation, it is anything but.

Our rapid production of greenhouse gasses since 1880 has caused the Arctic to warm, on average, by about 5.3 F (3.0 C). This rapid increase in warming is nearly 4 times that of…
