It is quite apparent that these people DO NOT WANT the alleged problem to prove to be a non problem. They cheer every time some new evidence can be construed to suggest that we're all going to fry, and seem quite upset every time some new evidence suggests that it's all ok, actually.

My personal favorite was a map showing red dots for all the places that the average temperature for some month was "the highest ever recorded". And there was a perfectly spaced grid with literally hundreds of points scattered throughout the oceans of the world. Probably true that the temperature was the "highest ever recorded" at each of those points, but with an even, perfect pattern like was shown, I couldn't help but wonder "How many years have they been recording that data?"

And do you really think that mankind can substantially increase the temperature on the surface of earth more than some breaking down of the insulation of the rock, dirt, water, etc that is on the surface? Or the gradual heat transfer that is happening from the core to the surface of the planet? Quick Google search says that it is estimated that the temperature at the core of the earth is over 10,000 F. So, there is one whale of a lot of heat being radiated up from below.

Not doubting that Man has his local impacts. But to try and imply that we are the cause of all the changes? I think someone has a bit too high an opinion of himself...

Just my thoughts. I won't be selling off my fleet based on this latest prediction.

And a whole load of rock to insulate us. Average heat flow from the interior is around 0.08W/m^2 at the surface, compared to 700 - 1400W/m^2 from the sun. So yes, the hot core has an effect but it's pretty small.

We're the cause of one slow trend, superimposed on other trends and other oscillations. We turn trapped carbon into CO2, CO2 absorbs infrared and heats up, so a small change in the 0.04% CO2 atmosphere content means a small but inexorable warming.

The climate in 50 or 100 years is still up for debate, most of it around the effects and prevalence of clouds, but it's never a good idea to crap in your own nest.

Hey ho. Happy Tuesday.
