Former Vice President Al Gore has weighed in on the record cold and snow in the U.S. “It’s bitter cold in parts of the US, but climate scientist Dr. Michael Mann explains that’s exactly what we should expect from the climate crisis,” Gore wrote on January 4 on Twitter.
Gore linked to one of his organizations’ articles on the brutal winter weather written by Climategate professor Michael Mann: The Climate Reality Project: A ‘PERFECT STORM’: EXTREME WINTER WEATHER, BITTER COLD, AND CLIMATE CHANGE
Gore’s Oscar-winning documentary An Inconvenient Truth did not warn of record cold and increasing snowfalls as a consequence of man-made global warming. And as recently as 2009, Gore was hyping the lack of snow as evidence for man-made global warming. Source: “Gore Reports Snow and Ice Across the World Vanishing Quickly.”
Other climate activists warned of less cold and snow as well.
Predictions of less snow and less severe winters were hammered into the public by global warming scientists. But once that predictions failed to come true, the opposite of what they predicted instead became—what they expected.
If “climate change” is causing record cold and snow, then it would stand to reason that Gore is suggesting that if the U.S. had ratified the UN’s Kyoto Protocol treaty on “global warming” back in the 1990’s — the winter of 2018 would have been warmer?
‘Insanity…It’s Witchcraft’ – Meteorologist Joe Bastardi on claims that cold & snow caused by ‘global warming’ – WeatherBell Meteorologist Joe Bastardi on January 4, 2018: “This is flat out insanity and deception now To tell the public that events that have occurred countless times before with no climate change attribution, is now just that, is not science, its witchcraft. NO PROOF AT ALL. Its climate ambulance chasing, nothing more.”
Bastardi added: “This has happened countless times before and it wasn’t global warming then and is not now. Solid use of past patterns predicted major early cold from OCTOBER! I have tweeted that dozens of times showing the analog years I used, No co2 then.”
Climatologist Dr. Roger Pielke Sr. also weighed in, explaining: “For those who claim USA/Canada nor’easter is stronger because of ‘global warming’, they apparently do not realize that it’s so strong because of especially strong horizontal temperature gradient in troposphere. It ‘bombed’ because of usually cold air!”
Update: Global Warming Is Not Causing Harsh Winter Weather – Daily Caller – Excerpts: Kevin Trenberth, a scientist with the National Center for Atmospheric Research, said “winter storms are a manifestation of winter, not climate change.” …
“Such claims make no sense and are inconsistent with observations and the best science,” University of Washington climatologist Cliff Mass said of claims made by Mann and others. “The frequency of cold waves have decreased during the past fifty years, not increased. That alone shows that such claims are baseless.” “And on a personal note, it is very disappointing that members of my profession are making such obviously bogus claims,” Mass said. “It hurts the science, it hurts the credibility of climate scientists, and weakens our ability to be taken seriously by society.” …
Every winter seems to reignite the global warming debate. Things got intense in 2014 when former White House science czar John Holdren put out a video where he claimed that year’s “polar vortex” was actually a sign of global warming. Holdren’s video was largely based on research by Rutgers University scientist Jennifer Francis, which claims that warming in the Arctic is making the jet stream more wobbly, making cold snaps and nor’easter storms more frequent. Holdren later admitted that his video was based on his “personal opinion” of the science, but the argument is still used every time cold Arctic air pours down through the lower 48 states.
Mann wrote that global warming may be “causing the jet stream to meander in a particular pattern” that causes cold spells in the eastern U.S. Mann suggested this pattern was being driven by “the dramatic loss of sea ice in the Arctic.” Yet, scientists aren’t sold on this theory. Mass noted how theoretical research shows the opposite happening, future warming would drive less undulation in the jet stream and heat up the area responsible for cold spells in the U.S. “Research documented in peer-reviewed journals has demonstrated that there is no evidence for their claims of increasing frequency of ‘lazy jet streams’ and blocking over time,” Mass said. “If you substantially warm the source region of cold air, cold waves will decline,” Mass said. A 2014 study led by Colorado State University climate scientist Elizabeth Barnes found no evidence to back up the theory that a lazy or wobbling jet stream was becoming more frequent. “There is much disagreement on whether we have already witnessed substantial impacts,” Barnes wrote in a Thursday blog post for the Climate Variability and Predictability program. …
Climatologist Judith Curry said the “bomb cyclone” currently hammering North America is nothing new. Those extra-tropical storms have undergone “bombogenesis,” or rapid intensification. “The term ‘bomb’ for such storms was coined almost 40 years ago by MIT’s Fred Sanders,” Curry told TheDCNF, “who spent much of his career studying such storms back when global warming most definitely was not a factor.” …
Curry said that while “warmer oceans can cause greater snowfall,” storm intensity is also influenced ” by the patterns of sea surface temperature not so much the average temperatures.” But Mann’s arguments are more based on expectations of what could happen with more warming, and have little to do with current trends in “bomb cyclones.” Weather.us meteorologist Ryan Maue, an expert on cyclones, pointed out there are between 50 and 60 “bomb cyclones” every year in the Northern Hemisphere, many of which we don’t notice because they are too far out at sea. But Maue’s research on “bomb cyclones” also don’t show any discernible trends from 1979 to 2010.
