Yes, I think the evidence is in favour of anthropogenic climate change.
I don't think it is too serious though, millions of people/species will die but humanity itself or the ecosystem is not under threat.
Nuclear fusion is the only viable way can see of solving it, as well as fuel security and increased prices as oil/gas run out. CO2 trading or hoping that nations implement agreements is too slow and not effective enough. All the current renewables have serious issues. Fusion is completely safe and completely scalable, it just needs investment.
