It looks like no one's answered my questions either.
I don't have a degree in climate science, but I can still comment on the subject. I've read the literature and research. A good start is this website as it has many arguments against denialist's claims:

You could say that pollution is an accepted negative consequence to live in first world conditions and to an extent, I agree. However, I think that we can change this by investing in new technology and reducing emissions. If we do not, we will make it increasingly harder to live good lives. Just look at the pollution in cities like Beijing - admittedly not entirely from coal power, but it causes massive health problems. I don't call that OK, by any means, it needs to change. If anything is going to kill us as a species off, it is massive environmental change. Until we have an established Mars colony, we can't go about destroying the Earth.
Solar and wind still cannot supply the necessary power that we as a population demand, and I do not see the demand reducing any time soon. So I am pro nuclear fission and hopeful that fusion will provide future needs. In the mean time, it is necessary to make changes to how power is generated. More nuclear, more wind, and more solar (where appropriate.) I support subsidies for solar/wind because in my mind, it levels the playing field. Coal and other technologies have huge unrealised externalities, that don't go accounted for. The coal plant doesn't pay for the harm caused by nearby residents, which makes coal cheaper than it really should be. I don't know at what level those subsidies should be set at but I think scrapping them altogether would be a bad thing.
