Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions.   view more (2007-11-08)

Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans-the growth of phytoplankton that forms the basis for the rest of the marine food chain-is tightly linked to climate change, and would be reduced by global warming.   view more (2006-12-07)

Cold climate produced by algae contributed to onset of multicellular life
The rise of multicellular animals about 540 million years ago was a turning point in the history of life. A group of Finnish scientists suggests a new climate-biosphere interaction mechanism for the underlying processes in a new study.   view more (2007-02-14)

Researchers in Finland working on a comprehensive model of the carbon cycle
Researchers in Finland are working to develop a comprehensive, multidisciplinary model of the carbon cycle and its impacts on climate change in northern ecosystems. The focus of work in the Academy of Finland’s Global Change Research Programme (FIGARE) has been on the uptake and release of... view more (2002-11-08)

Mass extinction's cause: 'Sick Earth'
What really caused the largest mass extinction in Earth's history?   view more (2006-10-23)

The light and dark of Venus
Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly.   view more (2008-02-22)

Two miles underground, strange bacteria are found thriving
A Princeton-led research group has discovered an isolated community of bacteria nearly two miles underground that derives all of its energy from the decay of radioactive rocks rather than from sunlight.   view more (2006-10-23)

Will global warming increase plant frost damage?
Widespread damage to plants from a sudden freeze that occurred across the Eastern United States from 5 April to 9 April 2007 was made worse because it had been preceded by two weeks of unusual warmth, according to an analysis published in the March 2008 issue of BioScience.   view more (2008-03-03)

No laughing matter -- bacteria are releasing a serious greenhouse gas
Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously.   view more (2008-03-31)

New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago,... view more (2005-06-10)

Bad sign for global warming: Thawing permafrost holds vast carbon pool
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.   view more (2008-09-04)

Snapshot of past climate reveals no ice in Antarctica millions of years ago
A snapshot of New Zealand's climate 40 million years ago reveals a greenhouse Earth, with warmer seas and little or no ice in Antarctica, according to research published this week in the journal Geology.    view more (2008-07-29)

Gene That Controls Ozone Resistance of Plants Could Lead to Drought-Resistant Crops
Biologists at the University of California, San Diego, working with collaborators at the University of Helsinki in Finland and two other European institutions, have elucidated the mechanism of a plant gene that controls the amount of atmospheric ozone entering a plant's leaves.   view more (2008-02-28)

Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.   view more (2008-10-24)

Improved foam for varicose veins found to be safe in preliminary results from phase II trial
A small group of patients with a common heart defect who were treated for varicose veins with an injectable microfoam experienced no neurological, visual or cardiac changes as a result of the treatment, according to preliminary results from a phase II trial.   view more (2008-03-17)

Burying the greenhouse gas
To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere.   view more (2008-11-18)

Forest fires may lead to cooling of northern climate
Countering hypotheses that forest fires in Alaska, Canada and Siberia warm the climate, scientists at UC Irvine have discovered that cooling may occur in areas where charred trees expose more snow, which reflects sunlight into space.   view more (2006-11-17)

Fires in far northern forests to have cooling, not warming, effect
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere.   view more (2006-11-17)

Icelandic volcano caused historic famine in Egypt, says Rutgers-based team
An environmental drama played out on the world stage in the late 18th century when a volcano killed 9,000 Icelanders and brought a famine to Egypt that reduced the population of the Nile valley by a sixth.   view more (2006-11-22)

Food-crop yields in future greenhouse-gas conditions lower than expected
Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions — and scientists warn that global food supplies could be at risk... view more (2006-06-30)

Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers.   view more (2008-09-15)

Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately.   view more (2006-09-15)

Scientists map steps to block key enzyme action in heart failure
Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.   view more (2008-11-12)

Elevated Carbon Dioxide Changes Soil Microbe Mix Below Plants
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide (CO2) reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen.   view more (2007-12-20)
