Anthropomorphic climate change is real. Where I disagree with some of the more alarmist scenarios is in over reliance upon incomplete climate modeling. There is a process called Global Dimming...basically low level pollution reduces the amount of global direct irradiance at the Earth's surface It is thought global dimming has a cooling effect and could counter-act the warming caused by CO2 emmissions. Studies indicate a reduction in global dimming since the 1990s..however with more recent economic development in China and India, areas of the World with little to no pollution reguation...global dimming is becoming a factor again over certain areas as low level smog blocks/reflects some of the Sun's radiation from warming the surface. What this means is less water evaporation...more drought..... Howver we're seeing polar sheet ice melting, and glacier melting and this contributes to the water evaporation process. It's a mixture of positive and negative feedbacks...and it complicates global climate models to accurately predict anything. There are lags in these effects...today's glacier melting might not reverberate into a noticeable climate change right away. It wasn't that long ago, the cover of Time magazine, or maybe it was Newsweek, had "Global Cooling" "The Next Ice Age" as their covers. In the 80's and 90's climate models predicted global cooling as the particulate matter from pollution reflected the Sun's radiation back into space...thus cooling the Earth. Since the beginning of this Century, virtually all climate models now predict extensive warming, some going so far as to predict run-away warming that will turn Earth into a Venus like oven. Frankly, I think climate modeling is an imperfect Science...alarmism tends to attract more grant money.
