Ja, i varje fall om man ska tro Jim Peden, en hyfsat välmeriterad fysiker. Han accepterar inte tanken att CO2 ger upphov till någon signifikant uppvärmning av atmosfären. Nedan ser ni ett utdrag ur ett av hans email som skickades till ett skeptikerforum.
I’ve studied the atomic absorption physics to death, from John Nicol’s extensive development to the much longer winded dissertation by Gerlich & Tscheuschner and everything in between, it simply doesn’t add up. Even if every single IR photon absorbed by a CO2 molecule were magically transformed into purely thermal translational modes, the pitifully small quantity of CO2 in the atmosphere doesn’t add up to much additional heat. And if the aforementioned magical 100% transformation from radiation into ”heat” were true, then all arguments concerning re-emission (source of all the wonderful ”greenhouse effect” cartoons with their arrows flying in all directions) are out the window.
More and more, I am becoming convinced that atmospheric heating is primarily by thermal conduction from the surface, whose temperature is determined primarily by solar absorption. I get a lot of email from laymen seeking simple answers. My simple reply goes like this:
1. The sun heats the earth
2. The earth heats the atmosphere
3. After the sun sets, the atmosphere cools back down.
With a parting comment: ”If we were to have 96 continuous hours without sunlight, temperatures would likely be below freezing over all the world’s land masses. The warmest place you could find would be to take a swim in the nearest ocean. There is no physical process in the atmosphere which ”traps” heat. The so-called ”greenhouse effect ” is a myth.”
