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. Kaufman, a geology professor at the University of Maryland. Kaufman and a team of international scientists found evidence the oxygenation of Earth's atmosphere coincided with the first widespread ice age on the planet 2 1/2 billion years ago. They theorize...

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.Methane bound up in ocean sediments and permafrost, called methane clathrate, has been a concern to scientists because of its huge volume, greenhouse gas potency and potential for release during periods of...

Emissions from wetlands around the Arctic may be responsible for higher atmospheric levels of the greenhouse gas methane that were noted last year.Extra amounts of the gas in the Arctic region are of biological origin, according to scientists. For nearly a decade global levels of methane had remained mostly stable.Rising levels in the arctic indicate that some of the methane stored away in permafrost is being released, which would result in major climatic implications.Methane is about 25...

By Timothy Gardner NEW YORK -- 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. "We may have less time than we think to do something (about the prospect of global warming)," Dr. Ira Leifer, a marine scientist at University of California Santa Barbara, said in an interview. Leifer is the main author of a study that looks at how "peak blowouts" of melting undersea formations called...

NASA -- 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. The OU Department of Earth Sciences team, PhD student Dave Kemp and supervisors Drs. Angela Coe and Anthony Cohen, along with Dr. Lorenz Schwark of the University of Cologne, discovered...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
