We are in trouble, folks. The mid-latitude regions are where most of the world's food is grown:

Arctic warming contributes to drought

According to new research, changes similar to those after the ice age 10,000 years ago could be in store today because a warming Arctic weakens the temperature difference between the tropics and the poles. This, in turn, results in less precipitation, weaker cyclones and weaker mid-latitude westerly wind flow -- a recipe for prolonged drought.

That's just the summary. Much more at the link.

Very interesting read

The temperature difference between the tropics and the poles drives a lot of weather. When those opposite temperatures are wider, the result is more precipitation, stronger cyclones and more robust wind flow. However, due to the Arctic ice melting and warming up the poles, those disparate temperatures are becoming closer.

"Our analysis shows that, when the Arctic is warmer, the jet stream and other wind patterns tend to be weaker," says Bryan Shuman, a UW professor in the Department of Geology and Geophysics. "The temperature difference in the Arctic and the tropics is less steep. The change brings less precipitation to the mid-latitudes."
I would like to point out that this study was published in Nature, one of the most prestigious scientific journals on the planet.

Seems to be odds with the research I read. The snow is melting faster because of daylight saving times. There is the same amount of sunlight, but the extra hour of afternoon sun is warmer than the hour of morning sun. Go back to standard time and the melting will slow down. Problem solved.

From your link, "According to new research, changes similar to those after the ice age 10,000 years ago could be in store today". Yes, the earth's climate repeats in a cycle and has done since the earth's formation. Unfortunately, us humans are here witnessing this cycle and apparently it's our fault. You would think these scientists used their brains they were born wi..... oh, hang on..... Money + Funding = Job.

PS - The first paragraph was sarcasm, apologises to anyone who didn't grasp it.

I love the conspiracy theory that the worlds scientific community is in collusion to fake scientific research results in order to get money, while totally ignoring the fact that the fossil fuel corporations have spent hundreds of millions on promoting the idea that climate research is all fake using a couple of sketchy "scientists" that also claimed that tobacco was not harmful to your health.

Yet they are taking away thousands of acres of land for solar panels when you you call that a crisis

These kind of hysterical predictions are not helping. I know the left just ignores it and moves on whenever these predictions fail to come true. But everyone else notices that every decade or so, someone announces that we only have 10 years left to save the planet.
