Planting new forests could contribute more to the mitigation of climate change than previously thought, according to a new study. This is due to the combined effect of land use changes and the enhanced carbon uptake of the terrestrial biosphere in a warm and high carbon dioxide climate, according to the study’s authors.

A long-dormant volcano outside Italy’s capital is entering a new eruptive cycle, a recently published study finds. Scientists previously assumed Colli Albani, a 15-kilometer (9-mile) semicircle of hills outside Rome, was an extinct volcano. But in recent years, scientists have observed new steam vents, earthquakes and a rise in ground level in the hills and surrounding area.

The phrase “tipping point” passed its own tipping point and caught fire after author Malcolm Gladwell’s so-named 2000 book. It’s now frequently used in discussions about climate change, but what are “climate tipping points”? And what do they mean for society and the economy?

Last year, scientists made a splash with the news that dark streaks on the Martian surface were signs of flowing liquid water. So far, they have been unable to determine where the water is coming from, but a new study uses recently acquired data of a large canyon system on Mars to eliminate some of the possibilities.

New research into the movements of dust around Jupiter’s four largest moons could help scientists searching for life in our solar system, according to a new study. This moon dust around Jupiter could give scientists clues about the composition of the surface of its satellites.

Electric fields in dust storms have been discovered lifting 10 times more dust into the air than winds alone, according to new experiments conducted in the Sahara Desert. The discovery has big implications for global climate studies, as well as for understanding dust storms on Mars.

Weather along the eastern coasts of South Africa, Asia, Australasia and South America will get significantly warmer and stormier on average over the next 100 years, a new study finds. The culprit? Climate changes that are causing ocean currents next to these coastal regions, called western boundary currents, to become stronger and extend further toward the poles, according to the new study.

Even if countries adhere to the Paris climate agreement hammered out last fall, capping global warming at 2 degrees Celsius (4 degrees Fahrenheit) would likely require net zero greenhouse gas emissions by 2085 and substantial negative emissions over the long term, according to an in-depth analysis by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.

There is some debate on what makes a river great. Is it its length? Its width? Ajit always thought it was more a matter of water volume, but after years of observing river plumes, he now opts for permanence. A river is great when its discharge has a detectable impact on the ocean; when its plume remains unmixed or fairly stable for a considerable period of time, without losing its idiosyncrasy.
