Like Stonehenge? Brits May Have To Thank The French – By Charles Choi, Inside Science – New research suggests that megaliths -- monuments such as Stonehenge created from large rocks during the Stone and Copper Ages in Europe -- owe their origins to a mysterious culture from northwest France with advanced seafaring technology.Roughly 35,000 megaliths are known throughout Europe, including standing ston

West Antarctic ice collapse may be prevented by snowing ocean water onto it – The ice sheet covering West Antarctica is at risk of sliding off into the ocean. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters.
