touché! As far as can be made out from the available literature, oxides of nitrogen seem to act more quickly than carbon dioxide when the solar storm hits, but either way there is a cooling effect from CO2 in the upper atmosphere. en.wikipedia.org/wiki/Mesopause[take notice of the warning at the top of the page!] "The complexity of the ionosphere-thermosphere-mesosphere (ITM) system of planet Earth" and a new abbreviation www.nasa.gov/mission_pages/sunearth/multimedia/itm-processes.htmleasy peasy ... |

Peter, on WuWT says
My god, don’t let the alarmists get ahold of the idea that CO2 can cause cooling, or in the decades to come they will be telling us we need to reduce to prevent global cooling.

Sadly this is possible. Anything and everything can be laid at the door of CO2 if you are so inclined. It's an all-purpose bogeyman.

“For the three day period, March 8th through 10th, the thermosphere absorbed 26 billion kWh of energy. Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space.”
How come the CO2 and NO didn’t re-radiate half of the energy downwards?
Enquiring minds would like to know…

Of course, incoming solar radiation is shortwave and generally, in climate science, they are discussing CO2 in terms of its impeding outgoing LW radiation of certain wavelengths - so maybe not strictly comparable?

"My god, don’t let the alarmists get ahold of the idea that CO2 can cause cooling"
It doesn't hurt to keep a cynical point of view, they have known these findings for some time. I saw it as a gradual shifting of position because they now accept [or realise that the hoypoloi won't now accept] the 'science is settled'. It's the politicians that worry me, they have made fuel so expensive that normal people have cut down vastly on vehicle use. Couple that with the general downturn in trade and industry plus the fact that vehicles in general produce less pollution than they did thirty years ago, we should be seeing at least a blip in the graphs for the last few years. With all this clean air flying around it small wonder that the climate has changed, when compared with say the 1970's.
