The Goldilocks principle: New hypothesis explains Earth's continued habitability
Researchers from USC and Nanjing University in China have documented evidence suggesting that part of the reason that the Earth has become neither sweltering like Venus nor frigid like Mars lies with a built-in ...
Long-term warming likely to be significant despite recent slowdown
A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.
Africa to spew half world's particle pollution by 2030, study says
With its exploding urban population burning ever more coal and wood, Africa could contribute as much as 55 percent of the world's particle pollutants by 2030, a study said Tuesday.
Enhanced photosynthesis is crucial for improving bioplastic yields from cyanobacteria
Traditional petrochemical plastics are made from non-renewable fossil fuels and cannot be readily assimilated back into the environment at the end of their useful life. Thus, there is considerable interest ...
Atmosphere models seek clues for rocky exoplanets
When a distant planet appears as a point of light in a telescope, it's hard to imagine what things are like at the surface. Does rain fall? Is the atmosphere thick, or dissipating into space? How constant ...
Is natural gas a solution to mitigating climate change?
(Phys.org) —Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane ...
Is global warming hiding underwater?
Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result ...
How did early Earth protect itself against the cold?
Earth's Sun was a weakling when it was younger. Around three or four billion years ago, the star's energy was about 20 percent to 25 percent lower than what's experienced today. If that was still true today, ...
Amazonian drought conditions add carbon dioxide to the atmosphere
(Phys.org) —International study combines aircraft and ground data to measure the "breath" of the Amazon forest
Potatoes could step up performance under climate change pressure
Research at the U.S. Department of Agriculture (USDA) suggests that potatoes are still the go-to tuber when times get tough.
Greenhouse 'time machine' sheds light on corn domestication
A grass called teosinte is thought to be the ancestor of corn, but it doesn't look much like corn at all. Smithsonian scientists were surprised to find that teosinte planted in growth chambers under climate ...
Ocean acidification leaving fish in the dark
Increasing carbon dioxide in the world's oceans could hamper fishes' eyesight, slowing their reaction times and leaving them vulnerable to predators or unable to hunt, new research has shown.
Sensitivity of carbon cycle to tropical temperature variations has doubled
The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed.
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
