We're going to have highs under 20 (-11 C) this week in Central Europe. So much for global warming.
I was wondering how many posts it would be before someone said that.
This is a direct result of global warming, as counterintuitive as that seems.
I was wondering how long it would take for someone to point out that absurdity..
Wanna learn, or you wanna stay ignorant and make fun?
Why don't you look up the coldest Historic Temp. for your State for this month?
I just did. . . I found out mine was in 1934. -54 F So. . Your supposition is apparently wrong.
Try again.
The internet really makes things super easy, instead of arguing, just look it up.
What supposition is that?
Where did I say it had never been colder here?
What does this cold snap have to do with global warming exactly?
Great question! I'm glad you asked!
What's happening here is a fragmentation of the polar vortex.
The polar vortex is a reservoir of very frigid air usually kept in place over the pole by the jet stream. The jet stream, as I'm sure you all know is a fast moving river of air that roughly circles the pole. The stream is drive by temperature differences between the polar air and the more temperate air to the south.
Now recently the globe has been warming, but it's not warming evenly. The poles are heating up much faster than the temperate zones, so there's less temperature differential between the two air masses that generate the jet stream. That makes the stream slower, and being slower makes it tend to wander or sometimes even break off chunks of arctic air.
A is how a normal polar vortex looks, and it gets progressively more fragmented as you move on through D.
