Growing up in BadAss Montana during the 60's and 70's and into the 80's we use to call these blasts from the north The Siberian Express. Global Climate Alarmist preferr calling them Polar Vortex. It sounds more serious and deadly and I suppose they're right because of the Solar Minimum the sun is going through right now, winters will become more severe and the polar air effects more of the planet. Every eleven yrs the sun goes through these solar minimums. I can't recall how long they usually last but the current is lasting longer then it ever has since the observation of sun spots began hundreds of years ago. Except once. And that was during the mini ice age. Russian climatologist are warning us this is what is occurring right now and will last at least a few decades. Some scientist are betting our that our 4% of co2 we contribute to the atmosphere may make it less severe. There's also growing support for this natural recurring change in the climate within the ranks of US climatologist but totally ignored by the IPCC and the MSM. No surprise there. If its true they'll all look like idiots.
I stumbled onto this real inconvenient truth when I dragged out my old telescope and found my notes on sun spots along with some sketches I drew up of sun spots. There were large islands of sunspots scattered all over the sun. Grabbing the sun filter and my grandson we went outside and pointed the filter at the sun and...WTF?
Where are all the sunspots? Not one. So I googled it and learned all about the solar minimum and the mini ice age right here on the Internet. And the evidence is right there up in the sky for everyone to see.
Oh. Almost forgot to mention what tree rings showed in Calf during the period of the MiniIce Age. A drought. A long dry drought. Good times!
And check out this 2006 Russian prediction if you have time. http://en.ria.ru/russia/20060825/53143686.html. I should warn you if you're a devout Alarmist you may not want to venture any further. it may mess with your belief in the Almighty and Infallible IPCC.
