• Does solar heating of the earth surface cause radiation of long wavelength infra red light? - yes
• Is this light absorbed by the atmosphere or escape in to space? - some is absorbed by the atmosphere, some escapes in to space
• What molecules in the atmosphere absorb this light? - water, carbon dioxide, methane and ozone
• What happens when this light is absorbed? - it is re-radiated in all directions, including back to the surface
• Are these molecules effectively global insulation? - yes, the Earth should have an average surface temperature of -18°C
• Is it reasonable to expect the concentration of molecules that form this insulation will have an effect on the insulation effect - yes

I don't think the above points are too controversial and we have had getting on for 200 years of science to prove these points wrong so far

There have been a lot of ideas on what cause climate change if it is not man made, including volcanoes and solar radiation changes. How can we mitigate these natural changes to prevent a global increase in temperature? Would lowering the insulation due to what we can control, namely carbon dioxide and methane do the job? Global engineering for the win!

It’s not like a thermostat! If we start interfering to this extent with natural processes, we could trigger the ice age that was predicted in the 1960s.
