re: #501 Thanos

The reality is that if you do increase the amount of CO2 in the atmosphere it will raise the temperature a slight amount. I have heard the number 0.00125 C as the first partial of the surface temperature per ppm of CO2 at the present 380 ppm. Frankly, I believe it since I know something of the field. The CO2 absorbtion lines in the infra-red are already opqaue as they can be for all practical purposes. Adding more CO2 does not make them more opaque at the surface, but raises the atltitude at which they become opaque. Thus we should see increased temperatures at about 10 km in the atmosphere which will be compoounded with an increase in absorpton by H20. Not only has this not been observed, but the stratospheric temperatures have been declining over the past 30+ years in the high stratosphere and are fairly constant in the lower stratosphere. There is no evidence of greenhouse warming. On the other hand the 30 years prior to 1999 were warmer. This is largely attribituable to the ATO/AMO cycle in the Atlantic. The gloabal temperatures increase for 30 years and then decrease for 30 years. If you will look at the Hadley data, you can easily see this at work.

As I have said, I do my own thing with solar panels, etc. as a hobby and to try and get off the grid. However, it makes for a crud energy policy at the domestic level.
