What a relief: According to Texas State Climatologist John Nielsen-Gammon, we don't need to worry about preventing the next glacial cycle; "with our CO2, we’ve taken care of that already"

5. To analyze the modern era, we need a model that can simulate the swings of glaciation and interglacials.

N-G: Wrong. Technically, it’s extremely hard to simulate the annual cycles of snow accumulation and melting with enough precision that you can pin down, to the tenth of a degree, how cool high latitudes would have to be in the summertime before ice sheets start accumulating again. I suppose you’d really like to be able to do that if global temperatures were going down and you were worried about needing to prevent the next glacial cycle. But with our CO2, we’ve taken care of that already. The question is what’s going to happen as temperatures continue to rise.

Nielson-Gammon's overweening confidence in his knowledge of future climate is a clear demonstration of what is wrong with climate science.We have second rate minds pretending to arcane knowledge and of an incredibly complex natural phenomenon and demanding major changes to civilization based on their opinions. If man was truly able to fend off the next ice age, it would be mankind's greatest accomplishment.
