Early Mars was covered in ice sheets, not flowing rivers, researchers say
by
•A large number of the valley networks scarring Mars’s surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new research. The …read more Source:: Science
Almost alien: Antarctic subglacial lakes are cold, dark and full of secrets
by
•More than half of the planet’s fresh water is in Antarctica. While most of it is frozen in the ice sheets, underneath the ice pools and streams of water flow …read more Source:: Science
Geologists determine early Earth was a ‘water world’ by studying exposed ocean crust
by
•Geologists have studied exposed, 3.2-billion-year-old ocean crust in Australia and used that rock data to build a quantitative, inverse model of ancient seawater. The model indicates the early Earth could …read more Source:: Science
Antarctic ice walls protect the climate

The world is getting wetter, yet water may become less available for North America and Eurasia
by
•With climate change, plants of the future will consume more water than in the present day, leading to less water available for people living in North America and Eurasia, according …read more Source:: Science
‘Artificial leaf’ successfully produces clean gas
by
•A widely-used gas that is currently produced from fossil fuels can instead be made by an ‘artificial leaf’ that uses only sunlight, carbon dioxide and water, and which could eventually …read more Source:: Science
Climate change may cut soil’s ability to absorb water
by
•Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to …read more Source:: Science
