Over at WUWT a commenter, Sleepalot Did a comparison of the Brazilian rainforest (Barcelos) and the N. African Desert (Adrar Algeria)

I looked at the data in more detail by looking at only non-rainy days. SEE comments, Here and Here.

The effect of the addition of water vapor (~ 4%) is not to raise the temperature but to even the temperature out. The monthly high is 10C lower and the monthly low is ~ 10C higher when the GHG H2O is added to the atmosphere in this example. The average temperature is about 4C lower in Brazil despite the fact that Algeria is further north above the tropic of Cancer. Some of the difference is from the effect of clouds/albedo but the dramatic effect on the temperature extremes is also from the humidity.
One would expect a drop in temperature of ~ 4C due to altitude for Adrar, Algeria so the difference between locations, taking into account altitude is ~ 8C higher in Adrar which is further north but with much lower humidity.

What no one ever mentions is GHGs modify the incoming sunlight in the daytime and the outgoing earthshine at night and this is a very short term modification. You can see the response time in this graph of solar eclipse data taken in the desert. GRAPH

Second since the wavelength distribution of incoming sunlight is much tighter than outgoing earthshine, sunlight has much greater energy per wavelength compared to the outgoing IR.

GRAPH

In this GRAPH note the graphic dirty trick of making incoming and outgoing the same shape. Also if only 15% to 30% of outgoing radiation is transmitted the earth would have been a cinder by now. Incoming HAS TO EQUAL outgoing over the long haul.

A more honest GRAPH

Another Graph no one ever shows. Note that the variation in Short Wave(SW) energy is not seen in the atmosphere but is absorbed by the earths surface, 70% of which is ocean.

There’s little doubt that when it comes to a fondness for pretty young chicks, he’s just another old perv. It’s nothing really unusual, and sadly, a lot of the people writing on this website might even have a Dad or Grandpa cheering DS on.

Steve Mennie and Drewski can kick and scream until their face turns blue – it’s pretty hard for the fanboys to spin the basic facts of this one. The email plainly states that Suzuki wanted tarted-up hotties to follow him around John Abbott.

My blog post simply points out that less infrared energy escaping from the Earth to space leads to net energy accumulation, and a temperature increase.

If you consider conservation of energy a “triviality”, I cannot help you Claes.

From above:
“energy accumulation and a temperature increase…..”

“Energy accumulation” but not necessarily “Temperature increase”
A temperature increase only if the atmosphere goes not expand. More heat[KE]; results in more volume; same temp.

Why does Dr S. not realize that?
