These are strange times.
What do you do when the political/economic consensus in no way reflects the scientific consensus and all its policy implications? Well, people have a choice: to resist the political consensus and try to create a new one, or to ignore the policy implications of the IPCC reports findings and to distract themselves with other things.
Such is the state of global capitalism today that despite many liberal political and business leaders claiming to believe in global warming, they seem to believe in free market fundamentalism and the public subsidy of the fossil fuel industry even more. (An odd ideological contradiction in and of itself.) The truth is, in dealing with any major social crisis where uncertainty or losing is not an option, state planning, public investment, and tight control of markets is needed on a major scale.
Every liberal capitalist nation turned to state planned investment and put markets on hold in order to mobilize labor and capital towards the social necessity of defeating fascism/Nazism during the Second World War. We need a similar movement today to subsidize clean energy research, ban fossil fuel extraction, and build clean energy infrastructure that the market left alone will currently not allow.
