Slate: The Earth Is Warming Faster Than It Has in 11,000 Years

(Continued)

Unfortunately, there's worse news: Pretty much every prediction by climate scientists shows that this rate will not slow, and in fact may have been underestimated. At Think Progress, Joe Romm took predictions from climatological literature and projected them into the near future:

The global temperature anomaly projected into the future shows we're in for trouble, a lot more than we have now.

A predicted rise of roughly 8 degrees F is not a joke, nor is it some sort of exaggeration for effect. It's the result of several studies showing just how much human activity is affecting our planet. We're pumping 30 billion tons of CO2 into the atmosphere every year - 100 times as much as all volcanoes combined - and all that carbon dioxide is upsetting the heat balance in our atmosphere. We retain more of the heat from sunlight, and that warms us up. It's really that simple, despite the frothing from the deny-o-sphere.

The bottom line here is the same as it has been for a long, long time: The planet is warming up. The rate at which the temperature is rising took a huge leap starting a century ago, and it's due to human activity. We're seeing the effects now, from the ice caps melting to changes in vegetation growth rates. There is no scientific controversy here, just a manufactured political and ideological one.
