Record cold from global warming causing ‘polar vortex’ debunked – ‘Paper confirms there is no evidence that climate change has slowed the jet stream or increased frequency of jet stream blocking’
New paper debunks claims that ‘Arctic amplification’ causes extreme weather — A new paper published in Geophysical Research Letters debunks claims that “Arctic amplification” is causing an increase of extreme weather in North America or the North Atlantic, finding such claims are “an artifact of the methodology” and not real. The paper finds no evidence of an increased frequency of jet stream blocking or a decrease of jet stream speed, a result corroborated by a recent paper finding no significant changes of the jet stream over the past 140 years. The paper debunks claims by climate alarmists such as Heidi Cullen [and Jennifer Francis] that “Arctic amplification” is causing a “constipated jet stream” leading to increased extreme weather in North America.
…Scientists reject claims of record cold being caused by ‘global warming’ – Time Mag. blamed ‘polar vortex’ on ‘global cooling’ in 1974 – Special Report
Global warming activists in academia and the media are now seeking to link record-breaking cold to man-made “global warming.” The problem is, the science is failing to support their claims.
Time Magazine was one of the first media outlets out of the gate with an article by senior writer Bryan Walsh blaming the “historic cold snap” on “climate change” and warning readers that global warming will bring more record cold! “This week’s events show that climate change is almost certainly screwing with weather patterns ways that go beyond mere increases in temperature—meaning that you’d be smart to hold onto those winter coats for a while longer,” Walsh wrote.

Walsh went on to refer to the ubiquitous phrase “polar vortex” to attempt to explain how carbon dioxide emissions have essentially made the polar vortex “wobble like a drunk on his 4th martini.”
Time: Polar vortex is ‘wobbling like a drunk on his 4th martini.’
The only problem for Time Magazine is the publication is on record in 1974 blaming the same phenomenon on – global cooling!

Other warmists have joined in blaming record cold on “global warming.” Meteorologist Eric Holthaus, who announced in 2013 that he was going to have a vasectomy to help save the planet, boldly proclaimed on Twitter “Yes, you can thank global warming for this taste of the ‘polar vortex’.”
The Weather Channel weighed in with this article: “Though it seems counterintuitive – global warming bringing about extreme cold – the answer may be yes, according to scientists like Weather Underground’s Dr. Jeff Masters and Dr. Jennifer Francis.” And the UK Guardian writes: “Deep freeze gripping America may be tied to shrinking Arctic sea ice caused by manmade climate change, reports Climate Central.”
But scientists were quick to reject any link of record cold to man-made global warming. See:
Princeton Physicist Dr. Will Happer refutes claims that global warming is causing record cold: ‘Polar vortices have been around forever. They have almost nothing to do with more CO2 in the atmosphere’
Award-winning Princeton University Physicist Dr. Will Happer rejected the media and some scientists claims that the record U.S. cold is due to man-made global warming. Happer, explained the science in an exclusive interview with Climate Depot.
“Polar vortices have been around forever. They have almost nothing to do with more CO2 in the atmosphere,” Happer said in an exclusive interview with Climate Depot.
Happer continued: “Here is a thumbnail sketch of the physics. The poles have little sunshine even in summer, but especially in winter, like now in the Arctic. So the air over the poles rapidly gets bitterly cold because of radiation to dark space, with negligible replenishment of heat from sunlight. The sinking cold air is replaced by warmer air flowing in from the south at high altitudes. Since the earth is rotating, the air flowing in from the south has to start rotating faster to the west, just like a figure skater rotates faster if she pulls in her arms. This forms the polar vortex. The extremely cold air at the bottom of the vortex can be carried south by meanders of the jet stream at the edge of the vortex. We will have to live with polar vortices as long as the sun shines and the earth rotates.
Like any fluid system at “high Reynolds number,” the jet stream is highly unstable, and from time to time it develops meanders to low latitudes, like the one we have had the past few days. About this time of year in 1777, just before the Battle of Princeton, there was a similar sequence. On January 2, Cornwallis’s men marched south from New York City through cold rain and muddy roads to try to trap George Washington and his little Continental Army in Trenton . On the night of January 2-3, a polar vortex swept across New Jersey, with snow and a very hard freeze. Aided by the extremely cold weather, Washington was able to evacuate his troops and artillery over newly frozen roads and to avoid Cornwallis’s encirclement. Reaching Princeton on the viciously cold morning of January 3, Washington won another battle against the British and escaped to winter quarters in Morristown. Thank you polar vortex!
