Global Temperature Trends From 2500 B.C. To 2040 A.D. [Awesome chart]
Long Range Weather.com ^ | Cliff Harris & Randy Mann

Until recently, global temperatures were more than a degree Fahrenheit warmer when compared to the overall 20th Century mean. From August of 2007 through February of 2008, the Earth’s mean reading dropped to near the 200-year average temperature of 57 degrees. Since that time, the mean reading has been fluctuating. (See Long-Term Chart Below.)

Unless you’re taking oil out of the ground.

“Grecian”? George Bush?

As you can see at 1100 BC everyone was hot for Helen of Troy and the temperature increased dramatically

It looks like temperatures have plummeted since Hillary of Little Rock came on the scene.

He said he couldn’t abandon his belief in man-made global warming without proof it isn’t real.

Did you explain the fallacy of proving a negative, vs the burden of proof that it is real which lies squarely on the shoulders of the scientists?

We can also theorize from the chart that Helen of Troy was more beautiful than Helen of Thomas.

I find it hard to believe that there is some kind of nexus between global cooling and volcanic activity. Any thoughts?

Solar output dips, Climate cools, Earths' crust cools, shrinks and moves causing earthquakes and volcanoes.

Well, off the top of my head - volcanic activity could eject a lot of crap into the atmosphere that could reflect back the suns radiation and cause cooling. But then it could also absorb more radiation and cause heating. So it could do both. The science is settled - the debate is over.

Did anyone besides me notice that every cooling period seems to be more intense than the pervious one?

That was the first thing I noticed. Each one is of longer duration and lower temps. The "area under the curve" increases significantly for each cold period.

I’m a little suspicious of this chart for the reasons you describe. And as a certified dumb guy, even I find it hard to believe that there is some kind of nexus between global cooling and volcanic activity. Any thoughts?

The "nexus" is between reduced solar activity and volcanic activity. The reduced solar activity alone would account for the temperature reductions. In addition, the increased volcanic activity on ocean floors increases evaporation. More snow increases surface albedo. More heat/light is reflected than absorbed.

Hip Hip Hooray!

That one seems pretty well established with “years without summer” in the history books following big eruptions.

Thought you all would like to read/see video of Al G being confronted in Chicago with another Inconvenient Truth: Climategate

Hint: It isn't pretty.

Ah yes, the well known ‘mobile warming’ phenomenon at work.

As found in the also well establish ‘global swarming’ which happens in the Spring when college profs take a break from teaching and the mushy minds escape for a short pause from indoctrination.

Gee, how did they record all those temperatures? Before this; In 1724 Gabriel Fahrenheit invented the first mercury thermometer.

What’s up with the estimated sharp increase in temps at the end - is this owl gore’s contribution to the chart?

I think it may be wishful thinking...agenda driven. It really bucks the long term trend.
