Paradoxically, you can blame global warming for the lingering winter weather
Anyone who thinks that the absence of traditional spring weather in certain locales at this late date somehow disproves theories of global warming has it exactly backwards, as we see HERE:
Climate scientists have linked the massive snowstorms and bitter spring weather now being experienced across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice.
Both the extent and the volume of the sea ice that forms and melts each year in the Arctic Ocean fell to an historic low last autumn, and satellite records published on Monday by the National Snow and Ice Data Centre (NSIDC) in Boulder, Colorado, show the ice extent is close to the minimum recorded for this time of year.
“The sea ice is going rapidly. It’s 80% less than it was just 30 years ago. There has been a dramatic loss. This is a symptom of global warming and it contributes to enhanced warming of the Arctic,” said Jennifer Francis, research professor with the Rutgers Institute of Coastal and Marine Science.
According to Francis and a growing body of other researchers, the Arctic ice loss adds heat to the ocean and atmosphere which shifts the position of the jet stream – the high-altitude river of air that steers storm systems and governs most weather in northern hemisphere.
“This is what is affecting the jet stream and leading to the extreme weather we are seeing in mid-latitudes,” she said. “It allows the cold air from the Arctic to plunge much further south. The pattern can be slow to change because the [southern] wave of the jet stream is getting bigger. It’s now at a near record position, so whatever weather you have now is going to stick around,” she said.
Francis linked the Arctic temperature rises to extreme weather in mid latitudes last year and warned in September that 2012’s record sea ice melt could lead to a cold winter in the UK and northern Europe.
