Theory, Meet Data
 

NOAA Reinstates July 1936 As Hottest Month On Record | The Daily Caller

Every once in a rare while the truth escapes. No warming since 1936?:D

Now that's what I'm talking about.

Criminals often begin a full confession of their crimes only when presented with strong evidence of their guilt.

Why else would they reverse alterations made to the data record, is something larger looming?

Chicken Little get it wrong? :rolleyes:

Theory, Meet Data
 

It still shows an upward trends though....
Over the past 100 years

Interesting downward trend around 1905, I thought it was this:

Tunguska event - Wikipedia, the free encyclopedia

But Tunguska wasn't until 1908. Hmmm, it was probably thermometer calibration error. :)

Quite right, now look back over the entire history of the Earth. The trend has been going up and down the whole time. Why?

Because of humans, obviously.

The Earth is constantly (relative term here...) going in and out of ice ages and glacial/interglacial periods. We're still in a ice age. More specifically, we're in an interglacial period (period of warmer climate). Ice ages come and go due to a myriad of reasons (change in ocean and atmospheric circulation patterns...even volcanic eruptions). If I remember correctly, the current ice age is believed to have been started as a result of the Isthmus of Panama forming. This altered ocean currents as a result of the Pacific and Atlantic currents no longer being able to flow between one another.

I believe shifts between glacial and interglacial periods have to do with the Earths orbit, the Earths precession and the shift in the Earths axis.

It's been a while since I've researched this stuff, but it's truly fascinating stuff. Really mind boggling.

No. It's because I tossed a plastic bottle in the trash this morning after I drove my gasoline car to work.

Just kidding.... Honestly it is an interesting subject to research. History on a major time scale is very fascinating.
