Quote by: xyzer Since most agree the earth has been warming (with some reversals) over the past several thousands of years and our world climatological records are limited to much less than a century your contention is just sort of ridiculous!

Warming according to whom??? Who is this "most agree" that you speak of?

As I pointed out, traditional fluctuations show a dramatic rise - around 10,000 years - from the bottom of an Ice Age to a peak, whereupon it drops off dramatically over the next 20,000 years or so. We've already reached that high point 10 to 6 thousand years ago. With some fluctuations, we have been in a consistant cooling trend ever since... as historical fluctuations would suggest. And yet again, you fail to explain how the sudden recent and dramatic warming just coincidently coincides exactly with the onset of global human indurstrialization compounded by the human population explosion.

Quote by: xyzer ...Hey we didn't have the capability to measure global temps even 50 years ago!

Actually, we have 'official' global temperature records going back 150 years, but regardless, we now have the means to reconstruct global temperatures, through ice cores, tree rings, sediments, etc. etc. etc.

Quote by: xyzer Then the opportunists tie in the issue of human generated emissions as a causal factor in world climate fluctuations and there is no proof of this either.

There is a great deal of proof. That seems to be the point that escapes you.

Quote by: xyzer I cite the example of human caused emissions growing and yet the global temps are static for several years?

Cite a scientific source that says this negates the dramatic, overall warming trend of the past hundred years, or how the hottest year on record, 2005 - and 2006 being on the track for a new record - suggests temperatures are static.

Quote by: xyzer Prove it I say...I agree the earth has been getting generally warmer since the last Ice Age but It is a slow process and humans aint the cause! I'm a skeptic! You haven't squashed this doubter.

There's nothing slow about the current anomoly. In geological terms, the recent rise in temperatures has happened blindingly fast.

Quote by: xyzer By the way I remember reading in Time Magazine in the early 70s that the past decade plus had been much cooler and some scientists were predicting global cooling...rather than warming!!!!

Don't you guys ever tire of bringing up this old strawman? It was Newsweek Magazine, and it was essentially correct, based on two factors we now understand. One is the 70-80 year Gliessburg Solar Cycle, in which temperatures began declining around 1940, then began climbing again in the mid '70s. In fact, by historical precedents, the global temperatures should have declined much more dramatically during that period, rather than just leveling off.



The other factor was Global Dimming, a process by which particulate pollution -- aerosal particles -- absorbed solar energy and reflected it back into space. This 'diimming' trend has reversed, since developed nations have reduced the amount of particulate pollution, including the U.S. Clean Air Act. In a paradoxical feedback loop, the more we reduce this form of pollution, the less global dimming acts to counter greenhouse caused global warming.

Not to mention, xyzer, that the 'Ice Age' scare stemming from the Newsweek article, a single article based on a single scientific paper, lasted a couple of years, at most. Global Warming has been the subject of intense study for the past 25 years.
