Dear Dr Russell,

First, congratulations on your recent analysis and observations regarding the recent interaction of the massive coronal mass emission and the thermosphere.

On the other hand, I am sure you must be aware by now how your comments regarding the event are being used to suggest that CO2 in the lower atmosphere does not act as a ‘global warming’ gas. For instance, this article …

Global warming debunked: NASA report verifies carbon dioxide actually cools atmosphere

Do you concur with the author’s conclusion that “The result was an overall cooling effect that completely contradicts claims made by NASA’s own climatology division that greenhouse gases are a cause of global warming. “

Thank you in advance for any response

Hi Ron,

Thanks for your question. There has been a widespread misconception about what was discussed in this web release and I welcome the chance to clarify what we said. Nothing could be further from the truth to say that “The result was an overall cooling effect that completely contradicts claims made by NASA’s own climatology division that greenhouse gases are a cause of global warming. “ The cooling due to CO2 being referred to in our web article occurs 60 to 155 miles above the surface of the earth (100s of kilometers in altitude). SABER is looking at the energy balance and climate of the upper atmosphere, not down at the surface. This atmospheric region has no effect on global warming in the lower atmosphere near the earth surface. The earth surface is heated by the sun and then cooled by infrared radiation being radiated back to space. CO2 in the lower atmosphere is a strong absorber of this radiation ( as is other greenhouse gases) and it radiates much of this radiation back to the earth surface causing the warming to occur. I liken CO2 in the lower atmosphere to a thick blanket that traps much of the radiated heat from the surface preventing it from escaping resulting in warming in the lower atmosphere. As altitude increases, the “blanket” gets thinner letting more radiation escape to space. In the 60 to 155 mile altitude range reported on in our article, the “blanket” is very thin letting most of the CO2 radiation escape to space causing the cooling we refer to.

So first, the observations we reported on have no bearing on the question of global warming due to the greenhouse gas CO2 and secondly, they do not in any way contradict statements made by NASA , the IPCC or other reputable groups studying climate change that CO2 increases lead to global warming.

I hope this response addresses your question, but if you wish more information, do not hesitate to contact me.

Sincerely,

Jim Russell
SABER Principal Investigator
