Sunlight stimulates release of climate-warming gas from melting Arctic permafrost, study says
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into ...
Tropical collapse caused by lethal heat: Extreme temperatures blamed for 'dead zone'
Scientists have discovered why the 'broken world' following the worst extinction of all time lasted so long – it was simply too hot to survive.
Going to Earth's core for climate insights
(PhysOrg.com) -- The latest evidence of the dominant role humans play in changing Earth's climate comes not from observations of Earth's ocean, atmosphere or land surface, but from deep within its molten core.
Researchers show small robots can prepare lunar surface for NASA outpost
(PhysOrg.com) -- Small robots the size of riding mowers could prepare a safe landing site for NASA's Moon outpost, according to a NASA-sponsored study prepared by Astrobotic Technology Inc. with technical ...
The heat is on; NOAA, NASA say 2014 warmest year on record
For the third time in a decade, the globe sizzled to the hottest year on record, federal scientists announced Friday.
Research sheds new light on global warming trends
New research by a team of Florida State University scientists shows the first detailed look at global land surface warming trends over the last 100 years, illustrating precisely when and where different areas ...
Landscape 'transition zones' may influence where tornadoes strike
(Phys.org) —Areas where landscape shifts from urban to rural or forest to farmland may have a higher likelihood of severe weather and tornado touchdowns, a Purdue University study says.
China prepares for first lunar rover landing on the moon
China will attempt to land a probe carrying the country's first lunar rover on the moon Saturday in a major breakthrough for its ambitious space programme.
Scientists cast doubt on theory of what triggered Antarctic glaciation
A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica's ice sheet began forming. Ian Dalziel, research professor at The ...
Ancient streambed found on surface of Mars
Rounded pebbles on the surface of Mars indicate that a stream once flowed on the red planet, according to a new study by a team of scientists from NASA's Curiosity rover mission, including a University of ...
Landing is key puzzle in Mars trip, experts say
Landing astronauts safely on Mars is one of the biggest technological hurdles for any future manned mission to the Red Planet, even more complicated than last year's daring rover touchdown.
Caves point to thawing of Siberia
Evidence from Siberian caves suggests that a global temperature rise of 1.5 degrees Celsius could see permanently frozen ground thaw over a large area of Siberia, threatening release of carbon from soils, ...
Some plants in arid regions benefit from climate change, study finds
(Phys.org)—Dryland ecosystems cover 41% of the Earth's land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive ...
China to land first moon probe next year (Update)
China has said it will land an exploratory craft on the moon for the first time next year, as part of an ambitious space programme that includes a long-term plan to put a man on the moon.
