The non-stop sucker punches of frigid air also brought to the forefront the idea that global warming could paradoxically be behind them, with Arctic sea ice melt forcing wild dives in the jet stream up in the atmosphere.But it's a hotly debated idea that has spurred a flurry of research, some of which bolsters the connection but still leaves key questions unanswered and many atmospheric scientists skeptical.And of course linking any Arctic outbreak, just like any other singular weather event, to the effects of warming is difficult, at best. And in this particular case, experts cited different reasons for the return of the intruding Arctic air.
The polar vortex is a massive system of swirling air that usually contains cold air around the North Pole. It has been shifting for decades, researchers found -- but it has only recently become a household term, after it was blamed for causing record cold weather affecting some 200 million people in 2014.According to the study, over the past 30 years, the polar vortex has weakened, in part due to Arctic sea-ice loss linked to human-caused climate change. That weakening has prompted it to shift toward Europe and Asia in February. This means unusually cold days may become more common in February and March, the Weather Channel reported. At the same time, Europe is facing warmer winters.
The principal weather change likely to accompany the cooling trend is increased variability-alternating extremes of temperature and precipitation in any given area-which would almost certainly lower average crop yields.During cooler climatic periods the high-altitude winds are broken up into irregular cells by weaker and more plentiful pressure centers, causing formation of a "meridional circulation" pattern. These small, weak cells may stagnate over vast areas for many months, bringing unseasonably cold weather on one side and unseasonably warm weather on the other. Droughts and floods become more frequent and may alternate season to season, as they did last year in India. Thus, while the hemisphere as a whole is cooler, individual areas may alternately break temperature and precipitation records at both extremes.
This, Hansen wants to warn us, is a recipe for global warming disaster. The recent warm winters that Britain has experienced are a clear sign that the climate is changing, he says.
Climate change could be responsible for intensely cold winters in the US and UK, a new study has claimed.
Hahanow you are trying to steal my materialhehethat's pretty damn funny
I'll let whatever strawman that question was direct to answer for itself.
Ordinary peeps don't understand science, they think that means you were wrong.

You see, when you lie, or make shit up, you lose credibility. If you are changing other people's words, (fuck who knows why), you are lost.

Greenland Summit station sets new record for coldest July day, and coldest July temperature ever recorded in the NH
Semi-serious observation.With the cut back in coal combustion and the continued reduction in PM10 and PM2.5 emissions (along with other smog producing chemicals) could this be the clearing of the atmosphere so that a clear day would result in a much colder temperature due to thermal coupling direct to space?
As to the question about what is happening with Arctic temperatures, I don't think a definitive answer has been provided. At least within the realms of scientific enquiry.
