I recommend that everyone watch this brief Weather Channel segment titled “Blame Climate Change for Long Winter“, the video description states that, “In much of the country this winter has stretched well into spring. The Weather Channel meteorologist Julie Martin asks the experts if climate change is to blame.” The Weather Channel segment puts forth the case that the “Long Winter” was caused by “Global Climate Change”, whatever that means. This argument is supported by this Huffington Post article “Climate Change ‘Causing Colder British Winters’ Says Met Office Chief Scientist“.
“Dr Julia Slingo told ITV News global warming may be responsible for the extreme weather.” “It definitely seems like the warming of the arctic is ‘loading the dice’ over cold dry winters.”
“As Britain experienced freezing cold weather and snow, with thousands of homes across the UK without power, the government’s outgoing chief advisor warned last month that climate change will bring greater extremes.
After the coldest March for 50 years, Professor Sir John Beddington said Britain was already experiencing climate change.”
Accuweather also adds support in their piece, “Historic Snowstorm Records; Climate Change to Blame?”
“While the debate as to whether climate change is responsible for the rare May snow across the Plains and Upper Midwest continues, there is no question that the snowstorm is historical with numerous records broken.”
“Before this snowstorm, “no station has reported an inch or more of snowfall in Iowa in May since 1967,” stated General Forecaster Jim Lee in a report issued by National Weather Service’s Des Moines Office.
Not only did the 3.1 inches of snow in Omaha break the previous May record of 2.0 inches from 1945, but also marked the city’s first measurable snow in 46 years.
Thursday was only the second time in recorded history that Kansas City, Mo., received measurable snow in May. A total of 0.5 of an inch fell Thursday, while the only other such occurrence was May 3, 1907.”
“For some, the historical aspect of this snowstorm raises the question as to whether climate change is fully or partially responsible.”
However, there are apparently some dissenting opinions who don’t think that Anthropogenic Global Warming/Climate Change are the cause of Long Cold winters and late winter storms, e.g. in the same AccuWeather article:
AccuWeather.com Expert Senior Meteorologist Bernie Rayno weighed in by saying, “I do not believe this [snowstorm] has anything to do with climate change. It is ridiculous that ‘climate change’ is being blamed for seemingly everything recently.”
As such, let us explore an alternate explanation for this year’s Long Cold Winter and late season snowstorms. RSS Northern Polar Temperature Lower Troposphere (TLT) – Brightness Temperature Anomaly – 1979 to Present;
was -0.27° K/C in March, 2013. Note that RSS uses a base period of 1979-1998 (20 years) versus the WMO standard of 1981-2010.
Also in this 3-Year snapshot of RSS Northern Polar Temperature Lower Troposphere (TLT) – Brightness Temperature Anomaly – 1979 to Present;
Northern Polar Troposphere Temperature is currently at its lowest point in the last three years.
I will leave it to WUWT’s readers to sort this one out…
