Did I hear Lord Rees correctly?  Did he refer to Greta Thunberg, Bill Gates, and Pope Francis as persons to whom we should listen and follow on climate change?  Let's see, an angry teenager, who is apparently truant, a left-wing Pope steeped in Peronism with antipathy for the United States, and a Malthusian billionaire maker of unsatisfactory software.  I don't think so.  Lord Rees is a brilliant man, but no one is brilliant about everything.
