Methane doesn't necessarily mean life on Mars, says Dartmouth study
Two Dartmouth researchers have weighed in on the debate over whether the presence of methane gas on Mars indicates life on the red planet. Mukul Sharma, Assistant Professor of Earth Sciences, and Chris Oze, a postdoctoral fellow, argue that the Martian methane could have been produced by inorganic processes just as easily as by bacteria. view more (2005-06-08)
Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't. view more (2008-03-12)
New isotope molecule may add to Venus' greenhouse effect
Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus. view more (2007-10-11)
Deep-sea sediments could safely store man-made carbon dioxide
An innovative solution for the man-made carbon dioxide fouling our skies could rest far beneath the surface of the ocean, say scientists at Harvard University. view more (2006-08-08)
Southern ocean carbon sink weakened
Scientists have observed the first evidence that the Southern Ocean's ability to absorb the major greenhouse gas, carbon dioxide, has weakened by about 15 per cent per decade since 1981. view more (2007-05-21)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
EARLY PROMISE OF SIMPLE TEST FOR DIAGNOSING MALIGNANT HYPERTHERMIA (p 1579)
German authors of a research letter in this week’s issue of THE LANCET describe the potential of a straightforward test for identifying people at risk of the often fatal reaction to general anaesthetics, a syndrome known as malignant hyperthermia. Malignant hyperthermia (MH) is a chain-reaction event triggered in susceptible individuals by... view more... (2002-05-01)
Meteorite bombardment may have made Earth more habitable, says study
Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres. view more (2009-06-02)
CO2 emissions increasing faster than expected
Carbon dioxide emissions from fossil fuels - the principal driver of climate change - have accelerated globally at a far greater rate than expected over recent years. view more (2007-05-22)
Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
Carbon sinks losing the battle with rising emissions
The stabilising influence that land and ocean carbon sinks have on rising carbon emissions is gradually weakening, say scientists attending this week's international Copenhagen Climate Change Conference. view more (2009-03-17)
Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate. view more (2008-09-12)

CT colonography even safer than previously reported, says study
The safety profile for CT colonography (CTC) is extremely favorable, particularly for the purposes of screening patients with no symptoms and when distending the colon using an automated carbon dioxide technique, a finding that goes against the higher complication rates for CTC reported by other groups, according to a new study. view more (2006-05-02)
Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000. view more (2008-10-02)
Increasing carbon dioxide and decreasing oxygen in the oceans will make it harder for deep-sea animals to
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. view more (2009-04-20)
Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. view more (2008-12-10)
Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor. view more (2005-09-08)
Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. view more (2007-04-10)
Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. view more (2008-09-02)
