There's a lot of talk here about "carbon emissions". I would like to clear up a few misconceptions:
1. "Carbon emissions" are not carbon emissions. They are carbon dioxide emissions.
2. Carbon dioxide is not a pollutant. It is colourless, odourless, and completely harmless. Actually, it is better than harmless, it is demonstrably beneficial. Satellites have shown that the modest increase in carbon dioxide over the last few decades has already resulted in markedly increased global biomass, even after taking all Amazon and other forest clearing into account.
3. The pollution in India's air is predominantly from huge numbers of open fires in citizens' houses. They use anything combustible that they can get their hands on - sticks, cow dung, etc.
4. Badly-run coal-fired power stations do produce real pollution. The technology to cut that pollution to entirely acceptable levels does exist and is used throughout western nations. (With some plants that still aren't up to standard, unfortunately.)
5. Even today carbon dioxide is only about 0.04% of the atmosphere. That's 4 parts in 10,000, or 400ppm. Optimal carbon dioxide concentration for plant growth is at least 1,000ppm - the concentration that many greenhouse owners use.
6. Carbon dioxide concentration is at around a 50 million year low. For nearly all of Earth's existence it has been many times today's level.
7. It is desperately important that carbon dioxide levels are not allowed to go markedly lower. At around 180ppm plants die - and hence we would die too.
8. Coal is still cheaper than renewables for power generation. That's partly because it is dispatchable. Renewables power stations need 100% backup available at instant short notice. That's a crippling cost, as demonstrated by power costs being highest where renewables usage is highest (South Australia is #1, followed by Germany and Denmark).
All of the above are well-known and demonstrable.
Also true, but harder to demonstrate:
9. The climate models are useless for predicting climate. [This is in fact demonstrable, because the IPCC never refer to the output from a computer model as a prediction. They only use the word projection.]
10. Man-made carbon dioxide has little effect on climate. The standard measure is called "climate sensitivity", and many many peer-reviewed papers put it at a fraction of the value typically used by climate models - but science has always been ferociously resistant to paradigm shifts and climate is no exception.
I hope that helps.
