Is the Earth currently experiencing a warming trend? Yes.
Are human activities, including the burning of fossil fuel and forest conversion, the primary — or even significant — drivers of this current temperature trend? The scientifically appropriate answer — cautious and conforming to the known facts — is: probably not.
" ** The Earth's climate cycles through 90,000-year Ice Ages interspersed with shorter warm periods."
Indeed, the current warming cycle is not unusual: Evidence from around the world shows that the Earth has experienced numerous climate cycles throughout its history. These cycles include glacial periods (more commonly known as Ice Ages) and interglacial periods, as well as smaller, though significant, fluctuations. During the past 20 years, scientists have been accumulating strong physical evidence that the Earth consistently goes through a climate cycle marked by alternating warmer and cooler periods over 1,500 years (plus or minus 500 years). The evidence indicates that: The Earth experienced a Little Ice Age from 1300 to 1850. A Modern Warming period began about 1850 and continues to the present.
Figure I tracks the Medieval Warming and Little Ice Age that preceded today’s Modern Warming.
We have long had physical evidence that the Earth has experienced numerous climate cycles throughout its history. The best-known of these is the Ice Age cycle, with 90,000-year Ice Ages interspersed with far shorter interglacial periods. What is new is the evidence of more moderate, persistent climate cycles within these broader cycles.
The message that the 1,500-year climate cycle is real, broad — and sudden — is being dug up from the Earth itself by modern science. The key evidence comes from very long-term proxies for temperature change, especially ice cores, seabed and lake sediments, and fossils of pollen grains and tiny sea creatures that document even small changes in Earth’s temperature over many thousands of years.
In addition, we have a number of shorter-term proxies (cave stalagmites, tree rings from trees both living and buried, boreholes and a wide variety of other temperature proxies) that testify to the global nature of the 1,500-year climate cycles.
A striking example of the effect of this 1,500-year climate cycle can be seen in the temperature-sensitive history of wine-growing in England.
" ** Evidence from every continent and ocean confirms the 1,500-year cycle."
The Romans grew wine grapes in England when they occupied it from the first through the fourth centuries. Aerial photography, remote sensing and large-scale excavation have recently revealed seven Roman-era vineyards in south central England. One site contains nearly four miles of bedding trenches that could have supported some 4,000 grapevines.
"majority will ever see Gore ..."
That's "never", not "ever" -- dang!
It was interesting to note that the latest "Global Warming" report was released on the same day we set a record low temperature here in the People's Republic.
Also, this has been the eighth coldest January (in Denver) since records have been kept (starting around 1880).
But, this is all proof of global warming, don't ya see?
Unfortunately, you make good points.
One of the great embarassing truths is that we have trees that tell the cyclic story, and thet are up to 3500 years old -

It's a great read
This one's pretty convincing, though:

abc news - yup - great scientific minds working there, yesiree!!

It's just another way for idiots to make money without trying and to tax us to death which I think they are doing a pretty good job at that.
During the Medievil Warm Period, sea levels were 10-15 FEET higher than today...
There is evidence of Global Warming on Mars and Pluto...
Al Gore must be IMMEDIATELY shot into space to becoem Dictator of Mars, and save the Plutonians from thier SUV's...
When you mention these FACTS to a follwer of the Religion of Global Warming, you get blank stares, then enraged, fanatical insults like "NAZI!!" or "BUSHBOT!!"
The "Great Global Warming Scare" is nothing more than the vehicle to push International Socialism toward it's goals of Global Control....

Thanks for more ammo, xcamel. :)
There are a number of articles that popped out in the last 48 hours...from the Canadian National Post...which spell out the vast efforts underway to disprove global warming.
http://www.canada.com/nationalpost/story.html?id=edae9952-3c3e-47ba-913f-7359a5c7f723&k=0
These Russian dudes mentioned in this article...are absolute in the heat trend peaking within 3 years...and their dire forecast spells out a cold blast by 2040...like the mini-freeze of the 1400-1700 period. The change in temperature will be noticeable by 2012.
The side of this that people ought to understand...is that we as a civilization have faced this over and over. IT is not the end of our lives or end of civilization. People change...people move....people adapt. Environmental folks have a natural tendency to blame...and to associate things with gobal business. I would urge them...in the strongest of ways...to learn the art of change. We will all pay more for heat within 40 years and there is no doubt that alternate forms of energy will be helpful in that period as we are going to need mega power in some regions (New England and Canda) to survive out this period. Farmers in the south...just hold up to 2040...and your crops will double up as people rely on you to feed more folks. We can make it during this cold spell...we've done it a thousand times. We don't need to go nuts and start vast programs to halt the global freeze.
Once the Kyoto Treaty is signed the "unstoppable" cycle will stop!
Not, so! I'll not be here to pay more in 40 years! And some of the others on FR tonight will not be here!
