Don't fall for his hand-waving and distractions and make him stick on point, David. Don't let him get away with distractions and keep coming back to his evidence behind the falsehoods before moving on.

Best,

D

Did you really say that non-anthropogenic CO2 increases the Earth's temp by 9 degrees?

Yes, but I meant "7", and I meant (but didn't say there's another 5 from other GHGs besides water vapor.) See Hafemeister and Schwartz, PHYSICS AND SOCIETY, v 37 n 3 (July 2008) p 3. It's widely available on the Web. First page, left-hand column.

I'll read you link tomorrow. I'm off to bed, but now I'm even more confused by your numbers. The temperature of the Earth without an atmosphere is 255 Kelvin. With the atmosphere, the temp is 288 K. So what will K be with an atmosphere without CO2?

David Appell said...

Without natural CO2 it seems the natural temperature of the atmosphere would be 255 + (33-7) = 281 K = 8 C

David, can you post a direct link to the article you refer to? You didn't give a title to the piece, so I don't want to analyze the wrong one. I worked too long of a day yesterday to try and find it.

I hope the end of your equation was just a typo? 255 + (33-7) = 281 K = 8 C

David:

For a so-called scientist, you seemed to have a rather superficial understanding of the science involved. Moreover, ad hominem slurs and argument by reference to what you deem to be authority really demeans you and your argument. More importantly, from the sound of your voice, even you didn't seem to believe much of what you were saying. A poor performance overall.

Nice article as for me. I'd like to read a bit more concerning this matter.
