At some point you realize that lib lefts plan of building some wind turbines and getting people to use less power won't work or be nearly enough(even if you get Europeans to accept a poorer lifestyle and freeze in the winter the rest of the world probably won't) and our only realistic chance of stopping or even reversing it is some technological breakthrough like Fusion power or even just much more economical nuclear fission.

Which is why people that say things like "Fusion research is a waste and we need to invest more in renewables" are so shortsighted and ignorant. The reality is that with current technology we can't become carbon neutral while keeping our living standards, it's one or the other. 
So we need research and hope for better technologies because I don't think telling people to accept poverty to prevent climate change is gonna work.

Also that doesn't mean that I'm against the expansion of renewable power just that I think it's only one part of the solution and we need more.

I mean the likely main byproduct of it is ^(3)Helium or ^(4)Helium depending on the fuel source. Which is great since there is also a Helium shortage. 

But the hard part with fusion is we don't exactly have piles of tritium lying around....
