Fossil fuels caused the greatest progress in history of mankind, and resulted in decimation of disease, famine and poverty. Green movement has spent the last 50 years opposing nuclear power, otherwise we would have decarbonised at least 90% already (like France has).
I can tell someone is going ask you for your "solution."
You know what the solution is, reader? Either support pro-nuclear policies until something better comes along, or shut up about climate change. In my experience, every single person who views climate change as an impending catastrophe responds with "but what if" when asked about nuclear. This is a widespread form of insanity. If we are headed for catastrophe, or extinction according to some, then the purely hypothetical world-ending events related to nuclear reactors shouldn't be any more of a problem. Personally, I'll take 100 Chernobyl-like events over extinction and a dying planet. Think that's crazy? Do the math.
