How do you even define, much less accurately measure, any such thing as "average" temperatures of the Earth's surface & atmosphere?
But, I get that you apparently believe anthropogenic CO2-induced climate change is a serious problem that needs to be solved. So, are you serious enough to support:
(1) "Manhattan projects" to develop promising sources of intensive almost unlimited CO2-free energy like nuclear fusion & satellite-based solar, brushing aside stupid fringe-leftist objections to the idea of plentiful energy?
(2) Trade sanctions against countries that manufacture things for export to us, using coal power that doesn't comply with standards imposed on American energy generators?
