<p>Why does CO2 cause heating in troposphere but cooling mesosphere?
Can anyone explain this?</p>

I recommend reading this paper: https://www.earth-syst-dynam.net/7/697/2016/esd-7-697-2016.pdf Quote: (i) the blocking effect, associated with a cooling due to the fact that CO2 absorbs
radiation at wavelengths where the atmosphere is already relatively opaque, and (ii) the indirect solar effect,
associated with a cooling in places where an additional (solar) heating term is present (which on Earth is particularly
the case in the upper parts of the ozone layer).

Hi Sachin, how much do you know about radiative transfer? Do you know what an optically thick/thin transition is? Just to establish what your previous knowledge is.
