I do like the IPCC

The IPCC, much reviled by know-very-little-but-think-they-know-it-all climate change skeptics, is an organization that calls climate change like it is: happening now, caused by humans, very likely to get worse. 

And since climate change is their thematic centrality, they don't worry much about some of the things that worry the rest of humankind, such as the peripheral issues surrounding safe, clean, low emission nuclear power.

Because of that, they are calling for a BIG increase in humankind's nuclear generating capacity to forestall the worst climate change paths that humanity could be headed upon.

IPCC Working Group III calls for nearly 4x nuclear energy

"At the global level scenarios reaching 450 ppm are also characterized by more rapid improvements in energy efficiency, a tripling to nearly a quadrupling of the share of zero- and low-carbon supply from renewables, nuclear energy AND fossil energy with carbon capture and storage (CCS) OR bioenergy with CCS (BECCS) by the year 2050. (p. 15)"

That's what has to happen.  If we are to keep on a path that avoids the worst climate calamities that we are currently creating for ourselves.
