Climate Shift, maybe so, maybe not?
I haven't been doing daily updates lately, falling behind, schedule has just been waaay to busy. I'll get back at it eventually. But in the meantime I've been doing some random reading on the net. This particular artical was very interesting to me.
http://www.physicstoday.org/vol-56/iss-8/p30.html
It discribes scientist discovery over time as to how long they estimated a possible climate change would actually take. From thousands of years to just a few years. Pretty incredible.
If the north ice cap starts melting, wich, most of you probably have herd, it has... it would cause a feed back loop where more ground is exposed, causing more light/heat to be absorbed, thus melting more of the ice cap, and so on. I know the north pole isn't as cold as it used to be. Cold fronts these past 6 years haven't been nearly as cold as they were previous to that, such as back in 1995-1998, I think it started significantly warming in 1998 and on. I'm basing this off the fact that Most of Seattle's snow relys on artic cold air masses sweeping down accross the candian rockeys, as if they head over the pacific they get warmed to the more moderate 36-40 degrees F. Sense about 1998 we haven't had any real cold spells dipping tempratures below the 30's for highs. I've seen some lower tempratures recently but only in the dead of a clear cold night, sometimes dropping into the teens. But it's been at least 10 years sense we've had a daytime high under 25 degrees.
I remember about 10 years ago the mid-west typically got alot of cold spells, bringing the tempratures into the negitives, even for highs... but recently that hasn't seemed to happen nearly as often. They also rely on the same source of cold air.
I think this clearly states the north pole has warmed up significantly. So I'm thinking soon that feedback effect will start up, if it hasn't already, and eventally enough fresh water will get into the ocean to cause alot more evaporating and more storms, wich will snow over the north pole and cause it to be cool once again. It could be mild or it could be dramitic for all I know. I mean the weather could start catching up slowly instead of quickly and snow on the north cap enough to keep it balanced out and cool to a normal rate again, Or... it could run away effect and melt quickly enough that it'll hit a snapping point, causing a major climate shift.
A popular theory I've been seeing running around lately is to much fresh water will shut down the north alantic current (Ever seen The Day after Tomarrow? That theory, only the storms most likily will not cirulate like a tropical hurricane. Truth is, it's still a complete mystery how such a weather event would have caused such severe freezing in minutes, like thoes theorised on that movie, but it has happened. They have indeed found frozen mammoths in tundra with food still in their mouths from grazing, indicating that they froze within a few minutes.
They have pulled several ice cores out of 3km deep ice in Greenland and technology has gotten advanced enough that they can look at each year's layer of ice, and they've gone back to when the last glaciation (ice age) started. By looking at the layers of ice in years, the northern hemisphere went from a temprate climate (today's climate) to that of the last glaciation period's climate in the matter of 3-5 years. They looked at even older glaciation periods and the same results. Alot of scientific groups, and even the scientist that discovered this them selves, find that very hard to believe, yet, it's there.
On the other side, comming out of the ice age, the climate change also only took a few years, to a decade or two. It just took alot longer for all that ice to melt under 40-70 degrees F weather, especially in places like here in the Pacific Northwest. Severe floods in Easter Washington along the Columbian river were probably due to more rapid melting due to the air being alot warmer over there, as it isn't moderated by the pacific trade winds so well with the Cascade mountains blocking the cooler pacific air. Google earth eastern washington sometime, you can literly see the many paths cut into the land that the columbian river once flooded through or flowed through. It once made the puget sound look like a stream.
Anyway, decided to share my thoughts on it. Feel free to comment.
