The academic authors have a fine record in identifying the causes and consequences of climate change, but their proposed solution simply doesn’t make sense.

The main problem is that, contrary what many think, nuclear power is a poor method of reducing carbon emissions: its uranium ore and fuel processes have heavy carbon footprints. Indeed, of the ways to reduce carbon emissions in the energy sphere, nuclear is by far the most expensive in terms of pound per tonne of carbon saved.
