Runaway Greenhouse Planet

Brett Smith for redOrbit.com - Your Universe Online When a planet absorbs too much solar radiation, its atmosphere reaches a tipping point - overheating, boiling its oceans and filling with steam. The result is an uninhabitable world much like Venus. This 'runaway greenhouse' phenomenon typically occurs just inside the habitable zone orbited by planets like Earth, and a new report in Nature Geoscience indicates that reaching the tipping point may be easier than previously thought....

More than 251 million years ago, at the end of the Permian period, Earth almost became a lifeless planet. Around 90 percent of all living species disappeared then, in what scientists have called "The Great Dying." Thomas J. Algeo, has spent much of the past decade investigating the chemical evidence buried in rocks formed during this major extinction. The University of Cincinnati professor of geology has worked with a team of scientific colleagues to understand the ancient catastrophe. Algeo...

Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide. The study, conducted by Andrew Lacis and colleagues at NASA's Goddard Institute for Space Studies (GISS) in New York, examined the nature of Earth's greenhouse effect and clarified the role that greenhouse gases and clouds play in absorbing outgoing infrared...

By Robert S. Boyd / McClatchy Newspapers It was the greatest mass murder of all time - poison everywhere, billions slain - but the killers have never been positively identified. An estimated 95 percent of marine species and 85 percent of land creatures died, said Peter Ward, a paleobiologist at the University of Washington in Seattle. Scientists call it "The Great Dying." Life took millions of years to recover. Scientific sleuths now think they're making progress toward learning what...

Earth sits between two worlds that have been devastated by climate catastrophes. In the effort to combat global warming, our neighbours can provide valuable insights into the way climate catastrophes affect planets. Modelling Earth's climate to predict its future has assumed tremendous importance in the light of mankind's influence on the atmosphere. The climate of our two neighbours is in stark contrast to that of our home planet, making data from ESA's Venus Express and Mars Express...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
