You don't understand it. But then again, you probably don't want to understand it. It says that when the warming comes, it will come quickly. It also says there is no known way to predict when. It could be now, or millions of years from now, but if the planet's cylces continue, it is coming.
Your article, OTOH, blames it all on humans (despite the fact that these warmings and coolings pre-date humans). It more specifically balmes capitalism (even if subtly). Funny that capitalism is also to blame for poverty, starvation, disease, racism, and every other world problem. At least all of the people come to the same conclusion: get rid of capitalism and the world becomes shangri-la.
