Wondering why North America is having unseasonably cold and snowy weather?

Growing evidence that global warming is driving crazy winters

It may be the timeliest - and most troubling - idea in climate science.

Back in 2012, two researchers with a particular interest in the Arctic, Rutgers' Jennifer Francis and the University of Wisconsin-Madison's Stephen Vavrus, published a paper called "Evidence linking Arctic amplification to extreme weather in mid-latitudes." In it, they suggested that the fact that the Arctic is warming so rapidly is leading to an unexpected but profound effect on the weather where the vast majority of Americans live - a change that, if their theory is correct, may have something to do with the extreme winter weather the US has seen lately.

In their paper, Francis and Vavrus suggested that a rapidly warming Arctic should interfere with the jet stream, the river of air high above us that flows eastward around the northern hemisphere and brings with it our weather. Sometimes, the jet stream flows relatively directly from west to east; but other times, it takes long, wavy loops, as in the image above. And according to Francis and Vavrus, Arctic warming should make the jet stream more wavy and loopy on average – some have called it "drunk" - with dramatic weather consequences.

These liberal neanderthals needs to stop Grubering the American people in their lust for more money and power.

Do you have any idea how ridiculous this sounds? Colder and snowier winters are the result of global warming. Remember, David Viner in 2000 confidently predicted that by 2014 there would be no snow and no winter due to global warming. Now, you expect us to believe that colder and harsher winters are the result of global warming?

You guys can't even decide which catacylsmic crisis we're on!

So, please, do us a favor and quit Grubering us! You will never convince us.

The problem is this headline uses the words "Global Warming". This confuses people who are ignorant about the science (facts) of climate change who read this to mean "warming" is "global" when in fact a changing climate does not mean a uniform warming but an average warming.

Not even 40% of our fellow citizens can name the three branches of US govt. Why would we expect them to distinguish climate from weather?

Everyone knows the three branches of government are Obama: 'me, myself and i'.

What I find to be most arrogant about the climatists among us is that they can use hudnreds of thousands of years worth of core ice data and CO2 emissions to predict with absolute certainty what is going to befall the planet in 2100. But, they can't use the exact same data to tell us what the sea levels will be in 2030. Of course, it is wholly consistent with their hegemony to tell us what's going to happen after no one alive today will be around to verify the veracity of their ridiculous doomsday predictions. I find that a decidely convenient

I mean, let's face it, no one believes these doomsday predictions.

But, I will make my own prediction. I predict by 2100 that we will still have cold temps and snow-riddled winters in Minnesota and the loons will still visit Owl Lake in Burnett County, Wisconsin every summer.

I guess I'll include you in the 60%.

How arrogant of you to make a prediction that no one alive today can verify. Convenient, indeed.
