Global Warming Not Primary Cause Of Svalbard-Area Methane Release
2014-01-03 07:47:38

redOrbit Staff & Wire Reports - Your Universe Online Natural processes, not global warming, are primarily to blame for the dissolution of the fragile, ice-like solid fuel substances known as methane hydrates, according to new research published online Thursday in the journal Science. Methane hydrates, which are composed of water and methane, are only stable in high pressure and low temperature conditions, the study authors explained. In some areas, such as in the North Atlantic off...

Arctic Seafloor Releases Double Previous Estimates Of Methane
2013-11-26 07:19:53

University of Alaska Fairbanks The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated, according to new research results published in the Nov. 24 edition of the journal Nature Geoscience. The East Siberian Arctic Shelf is venting at least 17 teragrams of the methane into the atmosphere each year. A teragram is equal to 1 million tons. “It is now on par with the methane being released from the arctic tundra, which is...

Ticking Time Bomb: The True Cost Of Arctic Methane Release
2013-07-25 07:44:29

redOrbit Staff & Wire Reports - Your Universe Online An Arctic methane 'time bomb' brought about by rapidly thinning permafrost could cost the world up to $60 Trillion, the size of the entire global economy, a group of economists and polar scientists warned on Tuesday. Methane is a powerful greenhouse gas, although it lasts less than a decade in the atmosphere. Large amounts of the gas are concentrated in the frozen Arctic tundra, and are also found as semi-solid gas hydrates under...

Arctic Warming Connected To Reduction Of Sea Ice And Increased Global Warming

Temperatures are rising four times faster in the Artic than the global average, a new University of Melbourne study shows. The combination of melting sea ice and global warming are contributing to the different rates. Professor Ian Simmonds from the University of Melbourne´s School of Earth Sciences, co-author of the study, said this information showed that a combined effect at ground and atmospheric level played a key role in raising the rate of warming in the Arctic. “Loss...

The ancient reserves of methane gas seeping from the melting Arctic ice cap told Jeff Chanton and fellow researchers what they already knew: As the permafrost thaws, there is a release of methane, a powerful greenhouse gas that causes climate warming. The trick was figuring out how much, said Chanton, the John W. Winchester Professor of Oceanography at Florida State University. The four-member team – whose findings were published in the respected journal Nature Geoscience –...

Thawing Arctic Cryosphere Releases Trapped Methane
2012-05-22 09:10:29

Brett Smith for RedOrbit.com The edges of glaciers and Arctic permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason. Researchers from the University of Alaska at Fairbanks just published a study in the online edition of Nature Geoscience showing that methane trapped under arctic lake ice for millions of years is now being released by the melting ice. The team used both aerial...

Ocean Found To Be Surprising Source Of Arctic Methane
2012-04-23 03:49:05

The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study by Eric Kort of NASA's Jet Propulsion Laboratory, Pasadena, Calif., has uncovered a surprising and potentially important new source of Arctic methane:...

A much reduced covering of snow, shorter winter season and thawing tundra. The effects of climate change in the Arctic are already here. And the changes are taking place significantly faster than previously thought. This is what emerges from a new research report on the Arctic, presented in Copenhagen this week. Margareta Johansson, from Lund University, is one of the researchers behind the report. Together with Terry Callaghan, a researcher at the Royal Swedish Academy of Sciences, Margareta...

Researchers develop technique to measure methane gas from cattle Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the...

No clathrate gun 40,000 years ago rapid warming led to an increase in methane concentration. The culprit for this increase has now been identified. Mainly wetlands in high northern latitudes caused the methane increase, as discovered by a research team from the University of Bern and the German Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. This result refutes an alternative theory discussed amongst experts, the so-called "clathrate gun hypothesis". The...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
