More Bad Climate News
By Ernest Stewart

"This land is your land, this land is my land, From California to the New York Island. From the redwood forest to the gulf stream waters. This land was made for you and me." ~~~ Woody Guthrie

From our "it's always something" department comes more bad news about global warming. According to a new study just out in "Nature Climate Change" by Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research and a group of co-authors, we're now seeing a slowdown of the great ocean circulation that, among other planetary roles, helps to partly drive the Gulf Stream off the U.S. East Coast. The consequences could be dire, including significant extra sea level rise for coastal cities like New York and Boston. This is due to, amongst other things, the fact that Greenland's ice cap is melting at an alarming rate. This causes a desalting with the input of all the fresh water from the melt off, thus destabilizing the conveyer system as there is no longer enough salt to cause the current to sink!

You may recall that the Gulf Stream transports more water than "all the world's rivers combined," according to the National Oceanic and Atmospheric Administration. But it's just one part of a larger regional ocean conveyor system that scientists technically call the "Atlantic meridional overturning circulation," which, in turn, is just one part of the larger global "thermohaline" circulation.

For the whole system, a key driver occurs in the North Atlantic ocean. Here, the warm Gulf Stream flows northward into cooler waters and splits into what is called the "North Atlantic Current." This stream flows still further toward northern latitudes, until it reaches points where colder, salty water sinks due to its greater density, and then travels back southward at depth.

This "overturning circulation" plays a major role in the climate, bringing warm water northward, thereby helping to warm Europe's climate, also sending cold water back towards the tropics. Trouble is, the Gulf Stream is just one part of the system that's failing because of global warming.

Here's a video from NASA that should help you visualize the thermohaline circulation for the entire globe. Rahmstorf also has a blog post up at explaining his research.

While this spells bad news for New York, Boston, Washington D.C., and other East Coast cities, the good news is it won't cause a "Day After Tomorrow" scenario as global warming will more than make up for it; and we won't become "Snowball Earth" again; nor will England and Europe get another mini ice age as they had from about 1300 till the mid 1800's.

Still, it's another nail in the global warming coffin; and we're to the point, where a few more nails will finish us off as a race. Forget about whether a Demoncrat or a Rethuglican wins in 2016, or if Israel manages to start WWIII; global warming is the biggest crisis Mankind has ever had to face, and one that will surely kill us off if we fail to stop it! We need to get our priorities straight, America, and very soon too!

We get by with a little help from our friends!
So please help us if you can...?


So how do you like Bush Lite so far?
And more importantly, what are you planning on doing about it?

Until the next time, Peace!
