A Serious Global Warming Question!

[Bobbieo]

It has been many years since I took geology courses but I do know the Japanese current flows north around the Arctic, and down the Alaskan, Canadian and California coasts. It is a cold current and with the melting Arctic ice I imagine the water will be even colder, now.

Along with the pollution blowing in from China on the prevailing Westerlies, I am wondering if this colder water will temporarily affect the west coast climate and bring on sudden periods of extreme temperature changes – like a July snowstorm in Los Angeles or a hundred degree temp in Anchorage.

1. There may be more of it but it won't be any colder. nt

2. I respectfully disagree

The one thing we've seen so far is complete unpredictability in the weather.

X-mas and New Years of 2000, I was running around in the mountains of Western VA in shorts and a T-shirt, yet that same year, over Memorial Day weekend, there was a freak blizzard that closed down several counties for three days.

Of most concern, to me personally, is the threat of widespread crop failures due to freak temperature swings, flooding, drought, freezing rain and hail. Granted, this has all occurred throughout history, but it seems to me we're seeing far more "wild" weather than ever before.

On a vaguely humorous note, it seems that the conservative, "red states" are bearing the brunt of the changes and damage. I always thought the FSM would take out San Francisco next.

It just ain't natural.

3. the currents will stop.. Ice age environments will develop, the poles Ice up and the equatorial

areas heat up and desertification spreads till there is a BIG brown band in the middle up to upper Capricorn's.. and a Green band will be left near the Ice sheets..the USA will become very cold and windy the Ice will flow in Glaciers down to about Ohio maybe virginia.. in 100 years there will less than 1 billion people alive and those probably wont be doing very well..

the ice sheet during the last Ice Age were 9 miles thick at the poles.. so much water was evaporated out of the oceans their levels were 150 to 180 feet lower than they are now..

it takes 5 pounds of red hot cast iron to vaporize 1 pound of water.. the heat will accumulate in the equatorial regions moving lots of water in accelerated currents to the poles.. spawning f6 or 7 hurricanes and tornado's..

as the perma frost melts it will release Methane hydrate and turbo charge the green house effect... it Mehtane hydrate deposits warm and crack they can detonate and expell many cubic miles of material into the upper atmosphere.. causing volcanic like dark winters lower temptures.. that will heat back up to where they started.. one such deposit in norway detonated and set the end of the ice Age back 5000 years..
