Global Warming and the Polar Vortex

Polar Vortex and climate change

You may be looking at this weather across much of North America and thinking, well, so much for global warming! That’s a relief. We’re gonna freeze to death, but at least we won’t boil to death!

Actually… it turns out that global warming may be the culprit for this cold weather.

The first thing to remember is that our global climate and weather systems are quite complex. When new factors are introduced, such as the heating effect of carbon and other greenhouse gases, the effect won’t simply be “it’s warmer”. For example, it will be warmer, but it will also be wetter – warm air holds more moisture. So in some parts of the globe, flooding will become a problem, and in others, record-breaking snowfall.

I know it’s hard to believe, but global warming can also make us colder. This has to do with the jetstream. Jetstreams are narrow bands of air at about 20,000 feet, that move our weather around. They get their energy – their speed – from the temperature differential between the Arctic and the mid-latitudes. As it turns out, the temperatures in the Arctic have been rising 2-3x faster than in the mid-latitudes, so the difference in temperatures between the Arctic and the mid-latitudes is dropping. As a result, the jetstream across the Northern Hemisphere has slowed down, and is taking a more meandering path.

Normally, that jetstream would move weather systems out more quickly, but now, it doesn’t have the speed to do that. So we have a polar vortex – a weather system that just keeps repeating, bringing in cold temperatures and lots of snow to the US and Canada, and ongoing thunderstorms and torrential rain to northern Europe.

Check out this video and report – it explains things very clearly:

So… global warming, and its chaotic effects on our climate and weather systems, is here to stay. The only question is – how bad will we let it get?

  1. We were searching for solving climate change and came across your Global Warming and the Polar Vortex | Jennifer Joy page. My greatest concern is energy, unless we end using dirty energy the earth is going to be in bad danger.
    I am surprised scientists are not looking at using more renewable energy like Ocean Turbines sort of like Crowd Energy LLC. If we dont solve this problem now its going to get bad.
    Thank you, Lavin
