With a massive loss of population fossil fuel carbon pollution would drop dramatically.

Before people started to die off due to climate effects some sort of Genocide would probably happen.

Would global temperature rise possibly create some other mitigating climate change to take place? Something like continuous global cloud cover or something else that counteract the green house effects.

Has not someone created a few self contained climate bubbles? How large a green house does it take to support 100 people?
