Despite constant claims to the contrary, the issue is not whether greenhouse gas emissions affect Earth's climate. The questions are whether those emissions are overwhelming the powerful natural forces that have always driven climate fluctuations, and whether humans are causing dangerous climate change.
No Real-World evidence supports a "dangerous manmade climate change" thesis. In fact, a moderately warmer planet with more atmospheric carbon dioxidewould hugely benefit crop, forest and other plant growth, wildlife and humans--with no or minimal climate effect. A colder planet with less CO2 would punish them. And a chillier CO2-deprived planet with less reliable, less affordable energy (from massive wind, solar and biofuel projects) would threaten habitats, species, nutrition and the poorest among us.
And yet, as Hurricane Matthew neared Florida on the very day the Paris climate accord secured enough signatures to bring it into force, politicians, activists and reporters refused to let that crisis go to waste.
