Yes, Virginia, it really has been a cold winter.
The winter months of December 2013 and January 2014 averaged over the contiguous 48 United States were the 3rd coldest Dec/Jan in the last 30 years…
Here’s a plot of the Dec/Jan averages for the last 41 years:
…An interesting feature is that 5 of the last 7 years have been below the 41-year average, which has happened only one other time in the 41-year period…
So, does the cold winter disprove global warming theory? No more than an unusually warm winter proves the theory. It’s just what we used to call “weather”.
Why are tree ring-based temperature “reconstructions” — like those of Michael “Limp Hockey Stick” Mann — so particularly galling? As the late John L. Daly explained, “The tree ring is a composite of [many] variables [including sunlight, pests, cloud cover, rainfall, and snow-packing], not merely of temperature. Therefore on the [scant] 15% of the planet covered by trees, their rings do not and cannot accurately record temperature in isolation from the other environmental variables.”
Exactly. And it turns out some scientists are now warning we may be witnessing the onset of a new ice age, in which case the blubber of certain portly faux scientists may come in handy.
