A new analysis of 2,000 years of tree ring data has quickly made climate change deniers' list of greatest hits to the theory of man made global warming. The tree rings "prove [the] climate was WARMER in Roman and Medieval times than it is now," the British newspaper the Daily Mail reported last week, "and [the] world has been cooling for 2,000 years." That and other articles suggest the current global warming trend is a mere blip when viewed in the context of natural temperature oscillations etched into tree rings over the past two millennia. The Star-Ledger, a New Jersey newspaper, mused that the findings lock in "one piece of an extremely complex puzzle that has been oversimplified by the Al Gores of the world."
In the past decade, hikers in Switzerland have been discovering previously unknown paths (and bodies/mummies?) which were hiked during the Medieval Warm Period, proving that same hypothesis.
Oversimplified hell. He outright lied about overstating every bit of data and then -acknowledged- it, saying that people wouldn't act unless he did so. Farkin' liberal maroons!
Actually it does support it however it has a greenie interpretation that tries to, as you have found out, make it sound otherwise. Call it a political rebuttal if you will.
Yes at the moment the globe is getting warmer, at this brief point in time, just like it did in the early 90's and dozens upon dozens of times in the past thousand of years. Trying to stop the warming cycle is futile and a waste of time and resources, we have bigger problems to solve. Given enough time this cycle too will pass and we will be headed for another ice age, I wonder what we are doing to cause that.

Just for fun. Here is a link to a retroactive look at a 1981 paper that looked at scenarios to predict global climate, taking into account many factors. It seems that 30 years later the observations have confirmed the predictions, including the role of CO2. or
My physicist daughter found the link, and yes, KNMI is the acronym of the Dutch weather service (Koninklijk Nederlands Meteorologisch Instituut), and I am a born Dutchman.
In geological times Earth's temperature has often been warmer than today, and part of the current rise in globally averaged temperatures may be due to other factors. It is just remarkable that 1981 calculations were able to predict observations made over the next 30 years, and were based on the rise in CO2. Really curious correlation ... Yes I know.
Nothing curious about it, Han ... when it comes to correlation and causation figures can lie, and liars can figure. Massage/adjust the data just right (as in the traditional and adjusted temperature data sets being used for modeling) and the moon is made of Limburger ... or at least smells like it. :)
And yes, we are definitely in a warming period ... however, the reason has simply not been determined with sufficient scientific certainty to embark upon the 'rob the rich, give to the poor' measures those intent on destroying the sovereignty of select nations in favor of a world government would have you believe.
Perhaps the most interesting ice age speculation would be the greenie response. What would the politically correct explanation be? And how could we battle "global cooling"?
Equally remarkable about 1981 is that it is an odd number year.
You can make any figures tell you what you want them to say. We do not know the reason for climate change or how long it will last of if the earth is naturally warming up to offset what did 40 years ago to cool thing off unknowingly. We are going thorough a normal cycle.
That said the current findings and bits of data collected may explain why the cave man is no longer around. His collection of data indicated that there should be no more cooking with fire as it added too much to the global pollution which was on every ones minds back then. They starved to death trying to save the world. ;~)

I hear and respect your doubts, Karl. I'm still with the general idea that manmade CO2 is a bad thing, and should be curbed as much as feasible. But I stil drive a 7 year old Grand Caravan ...
I agree, and certainly think there is indeed evidence to correlate the two, but, as a single cause, thus far it is far from sufficient to overcome my suspicion of political motives and agendas.
Sad world we live in ... one would have thought that ubiquitous, rapid means of communication could have mitigated the seeds of FUD, but so far it seems to have increased it exponentially.
---------------------------------- What is getting lost is the fact that there are over 30 million CO2 belching automobiles operating in China and India that weren't in operation 10 years ago.
Couple that with the clear cutting of the rain forests and you have a real out of balance CO2 situation.
It is only going to get more out of balance unless the problem is addressed.
The density and width of tree rings shows how warm it was during each year's growing season, and trees thereby serve as a record of long-term climate trends.

"However, the study actually does none of the above. "Our study doesn't go against anthropogenic global warming in any way," said Robert Wilson, a paleoclimatologist at the University of St. Andrews in Scotland and a co-author of the study, which appeared July 8 in the journal Nature Climate Change. The tree rings do help fill in a piece of Earth's complicated climate puzzle, he said. However, it is climate change deniers who seem to have misconstrued the bigger picture"
