Season's Greetings - Ask Santa for More Fleece!

Have you missed The Progger?  My apologies, I did indeed fall off the grid this past fall, but hopefully I'll be back on a more regular basis in 2011.

A few things to end out 2010.....first, a greeting card from all of us at Assateague Coastal Trust:

Next - has it been cold enough for you this December?   Well, here are some interesting blog postings from others that I think are worthy of re-posting for your reading pleasure.   Next time you're putting up with someone who pooh-poohs 'global warming' or 'climate change' just pass these along.

FROM MIKE TIDWELL, OF CHESAPEAKE CLIMATE ACTION NETWORK:
All,
See below some helpful blog posts explaining the recent cold weather in North America and Europe in the context of global warming. Turns out, the vanishing Arctic ice is creating a phenomenon similar to a refrigerator door being left open. The cold air is filling up the whole room but the refrigerator itself is being emptied of its vital coldness. The process is utterly unsustainable and leading to disruption and loss for the whole house.

From Eric Haxthausen of the Nature Conservancy:
The cold weather we have been experiencing on the East Coast is likely to sow further confusion in the minds of some Americans about whether the Earth is truly warming. I put together the blog post below to highlight some of the recent science about this, and thought it may be of interest. -Eric

Well, this is why we now use the term climate  change

Jeff Masters at the Weather Underground has a good post on what is happening with our weather that is making it so cold

And  there is a good graphic at NOAA website that explains it.

The explanation that is gaining currency among climate scientists is that low levels of Arctic sea ice during the summer are causing more heat to be absorbed in the Arctic during the fall, and changing atmospheric circulation patterns, driving cold Arctic air into Europe and the Eastern United States and funneling warm air up into the Arctic regions.

*This warm Arctic-cold continents pattern is likened to leaving the refrigerator door open. The room gets colder but the fridge warms up. *

This new pattern is very different from the one we are accustomed to. Case in point: the atmospheric circulation around the North pole actually reversed for a period of time last winter.
It also has the unfortunate byproduct that it generates a feedback loop that will tend to speed up warming, as it reinforces an atmospheric circulation that drives more warm air into the Arctic, melts more ice, allows darker land and water to absorb more sunlight, further warms the atmosphere in the Arctic, and thereby reinforces the new atmospheric circulation pattern.

So last night we had the unusual effect that the capital of Florida (Tallahassee) was colder (21° F this morning) than the capital of Greenland (with a low of 34° in the capital city Nuuk) or Iceland (43° in Reykjavik).

And as the globe continues to warm, we in DC and our counterparts in London might just need to get used to frigid winters.
