According to those espousing global warming climate change climate instability theory, human emissions of CO2 are producing warmer colder winters and less more snow in the Northern Hemisphere. Here’s a few examples. Bolded parts are my emphasis.
“Why are winters warming up so much faster over Northern Hemisphere continents than over the rest of the globe? A new study by NASA researchers in the June 3 issue of the journal Nature is the first to link the well-documented large degree of North America and Eurasia winter warming and the associated wind changes to rising greenhouse gas levels in the atmosphere.”

“Global warming will cause major changes to the climate of the U.S. Northeast if greenhouse gas emissions are not reduced, scientists said today. Warmer annual temperatures, less snow, more frequent droughts and more extreme rainstorms are expected if current warming trends continue, the scientists said in a new study, and time is running out for action to avoid such changes to the climate.”

“New research from UNH’s Climate Change Research Center’s Cameron Wake and his former graduate student Elizabeth Burakowski confirms what anyone enjoying today’s balmy temperatures might suspect: In the northeast, winters are indeed getting warmer. The duo conducted the most rigorous analysis to date of wintertime climate data in the northeastern U.S. from 1965 to 2005 and published their work recently in the Journal of Geophysical Research – Atmospheres.”
“Winter is warming faster than any other season and what we’re seeing over time is an intensification of this warming trend,” says Burakowski.

“A warmer Arctic climate is influencing the air pressure at the North Pole and shifting wind patterns on our planet. We can expect more cold and snowy winters in Europe, eastern Asia and eastern North America.
” ‘Cold and snowy winters will be the rule, rather than the exception,’ says Dr James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States. Dr Overland is at the International Polar Year Oslo Science Conference (IPY-OSC) to chair a session on polar climate feedbacks, amplification and teleconnections, including impacts on mid-latitudes.”

“That is why the Eastern United States, Northern Europe and East Asia have experienced extraordinarily snowy and cold winters since the turn of this century. Most forecasts have failed to predict these colder winters, however, because the primary drivers in their models are the oceans, which have been warming even as winters have grown chillier. They have ignored the snow in Siberia . . . The reality is, we’re freezing not in spite of climate change but because of it.“
– 2010, Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research (AER), writing in the Dec. 25 New York Times.
“The overall warming of Earth’s northern half could result in cold winters, new research shows. The shrinking of sea-ice in the eastern Arctic causes some regional heating of the lower levels of air — which may lead to strong anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, according to a study recently published in the Journal of Geophysical Research.”

“Europe’s cold winters and the warmth of the planet as a whole might even be linked. There is some evidence that the summer heat stored in the newly ice-free seas north of Siberia may induce shifts in the atmosphere’s circulation, when the heat is given up to the air in subsequent autumns and winters. Those shifts might in turn encourage seasonal patterns in which the Arctic is warm and the continents below it cold, as in early 2010. Since the sea-ice area looks likely to go on shrinking, such a link, if indeed it exists, would probably mean more cold winters in Britain and much of Europe.”

“But while piles of snow blocking your driveway hardly conjure images of a dangerously warming world, it doesn’t mean that climate change is a myth. The World Meteorological Organization recently reported that 2010 is almost certainly going to be one of the three warmest years on record, while 2001 to 2010 is already the hottest decade in recorded history. Indeed, according to some scientists, all of these events may actually be connected.
“One theory is that a warmer Arctic may actually lead to colder and snowier winters in the northern mid-latitudes. Even as countries like Britain — suffering through the coldest December on record — deal with low temperatures and unusual snow, the Arctic has kept on warming, with Greenland and Arctic Canada experiencing the hottest year on record.“

Bryan Walsh deserves a special award for climatological contortionism. Five months earlier, while discussing climate change’s predicted effects on agriculture, Walsh said matter-of-factly that climate change meant warmer winters:
“Of course, as writers like the climate contrarian Bjorn Lomborg have pointed out, cold winters tend to be even more deadly that hot summers, and since climate change will mean warmer winters as well, the overall impact on mortality might be blunted. But sizzling heat could ruin agriculture as well: a study in Science last July found a more than 90% chance that by the end of the century, average growing-season temperatures would be hotter than the most extreme levels recorded in the past, as I wrote on TIME.com last summer. . . Warmer winters won’t do us much good if we can’t feed ourselves while enjoying a balmy February. Something to think about during summer on Planet Earth.”
