Energy industry geophysicist.
It is my opinion as a geophysicist that human induced climate change is real, and there is no much we can do about, short of annihilating India and China, who are driving it. The USA is meeting CO2 goals due to use of nat gas instead of coal, better MPG cars, and the recession, unfortunately.
If the world breadbaskets fail year after year due to long term droughts in the mid latitudes, then we shall see where the sh## goes after it hits the fan and gets flung around.
Right now, China and India are intensely interested in fracking for nat gas, which could help get them to reduce coal use. I am involved with that. Coal is a terrible fuel. We also need more nukes. Nukes is something France did right.
