Ice-free summers in ancient Arctic may help predict future trends
Washington, July 10 (ANI): In a new research, scientists have obtained evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous period, which should help predict how the Arctic is likely to respond to future global warming.
The Late Cretaceous, the period between 100 and 65 million years ago [...]
The Arctic was an enclosed freshwater lake until about 38 million years ago
Washington, July 5 (ANI): An analysis by scientists has suggested that the Arctic was an enclosed freshwater lake until about 38 million years ago, when tectonic activity caused it to undergo a transition to an ocean.
Recent studies have suggested that beginning about 44 million years ago the Arctic underwent a transition from lake to ocean [...]
Rising climate warning affecting stability of West Antarctic Ice Sheet
Washington, March 19 (ANI): New evidence has emerged which determines that even a slight rise in atmospheric concentrations of carbon dioxide, one of the gases that drives global warming, affects the stability of the West Antarctic Ice Sheet (WAIS).
The massive WAIS covers the continent on the Pacific side of the Transantarctic Mountains. Any substantial [...]
