Thank Moss for Livable Planet

Plant may have prompted major shift in ancient climate

(Newser) - About 480 million years ago, the planet was a much hotter place—and we have moss to thank for the habitable Earth we enjoy today, research suggests. Back then, 16 times as much carbon dioxide existed in the atmosphere, scientists think. Some 20 million years later, carbon dioxide levels had...

Space Telescope Spots Earth-Sized Worlds

Kepler discoveries are smallest exoplanets yet found

(Newser) - For the first time, scientists have discovered planets roughly the size of ours outside our solar system. Kepler-20e and Kepler-20f are the smallest exoplanets yet found, Discovery reports. Because they're so close to the star they orbit, they don't appear habitable, but the finding is "next major...

Dead Sea Dried Up 120K Years Ago

And it's in danger of happening again

(Newser) - Scientists have discovered that the Dead Sea pretty much vanished 120,000 years ago when the earth was as warm, or slightly warmer, than it is today, reports the BBC . It's in danger of doing the same today, this time helped along by populated areas taking the water that...

NASA Spots Habitable Earth-Like Planet

Kepler-22b averages 72 degrees and may have oceans

(Newser) - Finally, an Earth-like planet where the weather is nice enough for an occasional visit. Only, it's 600 light-years away. Today NASA announced the existence of Kepler-22b, the first-ever planet discovered in the "habitable zone" of a sun-like star—where temperatures are placid enough to allow for water, ScienceNOW...

Planet Could Be 'Unrecognizable' in 40 Years

Population is getting richer, and competing for ever-scarcer resources
