Below is the pertinent part of the NASA article for anybody who thinks fc is not an ignorant troll.
Note, even trolls can see the the use of thermostat and "key role in energy balance".
Even ignorant trolls who drone out leftists agw lies can see how CO2 repels solar energy... thereby keeping the earth cooler.
Therefore, everybody with a brain would wonder...
Does more co2 cause more warming to stay in or more warming to stay out.
What is the net to the energy balance of adding more co2.. how do you know?

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
