New research is challenging the recent finding that plants could be a major source of the atmosphere's methane levels. A study from 2006 suggested plants could account for almost half of the global production of the greenhouse gas, yet a UK-based team has found that under normal conditions, plants just convey methane from the soil to the air without actually producing it. The research suggests identifying sources of methane is key for climate control, as the gas is about 20 times more potent...

The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate. But gathering physical evidence, backed by powerful simulations on the world's most advanced computer climate models, is reshaping that view and lending strong support to the radical idea that human-induced climate change began not 200 years ago, but thousands of years ago with the onset of large-scale agriculture in Asia and...

On Wednesday, researchers said the arctic tundra emits the same amount of methane in winter as in the warmer months, a surprising finding that bolsters understanding of how greenhouse gases interact with nature.Torben Christensen, a biogeochemist at Lund University in Sweden, said scientists have long known that wetlands produce large amounts of methane and had thought it unlikely that greenhouse gases escaped from beneath frozen tundra."Mother Nature is showing us something that is really...

The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end approximately a decade in which atmospheric levels of the potent greenhouse gas were essentially stable. The new study is based on data from a worldwide NASA-funded measurement network. Methane levels in the atmosphere have more than tripled since pre-industrial times, accounting for around one-fifth of the human contribution to greenhouse gas-driven global warming. Until recently, the leveling off of methane...

Carbon dioxide is only one of the greenhouse gases that make scientists stay up at night. Methane and nitrogen trifluoride are increasing which makes scientists worry about increasing global warming.  Methane is the greatest threat. It represents about one-third that of carbon dioxide produced by the burning of coal, oil and other fossil fuels.  As a greenhouse gas, methane is second to carbon dioxide.  Decaying plant material, land fills, natural gas, coal mining and animal...

Carbon buried in the Earth could ultimately determine the fate of our planet's atmosphere. So concluded a pioneering meeting last week about the Earth's long-neglected "deep" carbon cycle. Carbon is locked away down in the Earth's crust: in magma and old carbonate rocks buried by plate tectonics, in fossil fuels like coal and oil, and in ice lattices beneath the ocean bed. It has long been assumed that this carbon was largely cut off from the surface, and could safely be ignored when...

Researchers from the National Oceanographic and Atmospheric Administration Earth System Research Laboratory (ESRL) reported new data that shows a higher than usual average increase in carbon dioxide levels over the last 30 years.The recently released report from NOAA scientists is an annual update to the agency's greenhouse gas index, which tracks data from 60 regions around the world. Concentrations may have increased by as much as 0.5% from 2006 to 2007.CO2 levels jumped by 2.4 parts per...

New insights into natural changes in atmospheric methane concentrationsIce cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane concentrations over the...

Saturn's moon Titan is notorious for its shroud of organic haze. Recent experiments suggest that early Earth may have been covered by a similar haze. The discovery could shed light on how life spread around the globe. NASA - Saturn's giant moon Titan is enveloped by a thick layer of organic haze. Although Titan's haze layer is unique in the present-day solar system, a recent experiment by researchers at the University of Colorado at Boulder suggests that, billions of years ago, Earth was also...

By Jeremy Lovell LONDON (Reuters) - Many countries may be grossly underestimating the quantity of greenhouse gases they emit according to a new method of monitoring output, scientists said on Wednesday. The new "top-down" system measures the actual amount of gases such as carbon dioxide and methane in the atmosphere, compared with the traditional "bottom-up" method which estimates what is likely to be produced on the ground. The findings, still the subject of scientific debate,...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
