1. how many times do I have to present this link to you... you troll. see its from nasa science right around the time they kicked the agw nutter, hansen, out.
Yes by working in the upper atmosphere to repel the suns energy... CO2 calls the earth. The whole earth.

Mlynczak is the associate principal investigator for the SABER instrument onboard NASAâs TIMED satellite. SABER monitors infrared emissions from Earthâs upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air hundreds of km above our planetâs surface.
âCarbon dioxide and nitric oxide are natural thermostats,â explains James Russell of Hampton University, SABERâs principal investigator. âWhen the upper atmosphere (or âthermosphereâ) heats up, these molecules try as hard as they can to shed that heat back into space.â
Thatâs what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earthâs magnetic field. (On the âRichter Scale of Solar Flares,â X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe.
âThe thermosphere lit up like a Christmas tree,â says Russell. âIt began to glow intensely at infrared wavelengths as the thermostat effect kicked in.â
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.

New paper finds negative-feedback cooling from water vapor could almost completely offset warming from CO2
A new paper published in the Journal of Geophysical Research Atmospheres finds water vapor can act as a negative-feedback cooling effect to significantly counteract anthropogenic global warming.
According to the paper, "The satellite observations have shown that warming of the tropical Indian Ocean and tropical Western Pacific Ocean -- with resulting increased precipitation and water vapor there -- causes the opposite effect of cooling in the tropical tropopause region above the warming sea surface. Once the tropical tropopause cools, less water vapor is present in the tropical tropopause and also above in the stratosphere,
Since water vapor is a very strong greenhouse gas, this effect leads to a negative feedback on climate change. That is, the increase in water vapor due to enhanced evaporation from the warming oceans is confined to the near- surface area, while the stratosphere becomes drier. Hence, this effect may actually slightly weaken the more dire forecasted aspects of an increasing warming of our climate, the scientists say."
The paper itself says, "In the lower stratosphere, the changes in water vapor and temperature due to projected future sea surface temperatures are of similar strength to, though slightly weaker than, that due directly to projected future CO2, ozone, and methane," which would indicate that this negative-feedback cooling effect is almost equivalent to the warming effect of man-made CO2, ozone, and methane and could almost fully offset global warming.
The paper is similar to another recent paper published in Nature Climate Change, finding warming of sea surface temperatures in the Indian and Pacific Ocean 'warm pool' is causing less water vapor to enter the top of the troposphere and could cause global cooling from this negative-feedback. The papers add to many others finding water vapor acts as a negative-feedback, not positive as assumed by IPCC climate models. Climate model false assumptions of positive-feedback from water vapor are the entire basis of Mann-made global warming alarm.
