Earth's earliest ice age could have been caused by an atmospheric rise in oxygen reacting with methane, a greenhouse gas, a geologist in Maryland said. This singular event had a profound effect on the climate, and also on life, said Alan J.
An analysis of ancient Greenland ice suggests a spike in the greenhouse gas methane about 11,600 years ago originated from wetlands rather than the ocean floor or from permafrost, a finding that is good news according to the University of Colorado at Boulder scientist who led the study.
Emissions from wetlands around the Arctic may be responsible for higher atmospheric levels of the greenhouse gas methane that were noted last year.
If the world continues to get warmer, vast amounts of methane gas trapped in ice under the sea could belch up and worsen climate change, according to a study.
Open University researchers have uncovered startling new evidence about an extreme period of a sudden, fatal dose of global warming some 180 million years ago during the time of the dinosaurs. The scientists' findings could provide vital clues about climate change happening today and in the future.
