Oh, noes!!! The end of the world has been postponed from 2013 to 2100.

From Io9:
A new study on environmental changes suggests that our future may be warmer than we thought — 4 degrees C warmer, to be exact. That's how much hotter the planet will be in 2100, as a result of changes in cloud cover. And this could prove catastrophic for human life.
Over at the GuardianDamian Carrington notes that the 4 C rise is "twice what the world's governments deem dangerous" and is a higher estimate than what we've seen before from climate experts. That's because this new climate model accounts for changes in cloud cover:
The research indicates that fewer clouds form as the planet warms, meaning less sunlight is reflected back into space, driving temperatures up further still. The way clouds affect global warming has been the biggest mystery surrounding future climate change.
Professor Steven Sherwood, at the University of New South Wales, in Australia, who led the new work, said: "This study breaks new ground twice: first by identifying what is controlling the cloud changes and second by strongly discounting the lowest estimates of future global warming in favour of the higher and more damaging estimates."
"4C would likely be catastrophic rather than simply dangerous," Sherwood told the Guardian. "For example, it would make life difficult, if not impossible, in much of the tropics, and would guarantee the eventual melting of the Greenland ice sheetand some of the Antarctic ice sheet", with sea levels rising by many metres as a result.

These "futuristic" predictions are churned out like clockwork, and then forgotten when they fail.

Remember 2000 when the prediction was no more snow in Britain...ever?

How did that turn out?  [Hint.]

What isn't forgotten is the fear it sparks in people who haven't been keeping track of these bogus stories.
