Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O’Driscoll in SCI’s Chemistry & Industry magazine published today.
Shell is so impressed with the new approach that it […]

Plant-eating animals in highly seasonal environments, such as the Arctic, are struggling to locate nutritious food as a result of climate change, according to research that will be published in the 21 May 2008 online edition of the journal Proceedings of the Royal Society B. Led by Penn State Associate Professor of Biology Eric Post, […]

Since the 1980s, Dr. Joseph M. Prospero, professor of Marine and Atmospheric Chemistry at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, has pioneered studies in the worldwide measurement of aerosols, fine particles suspended in the atmosphere and carried by winds. His team’s work focuses on the aerosol chemistry of the marine […]

A new NASA-led study shows human-caused climate change has made an impact on a wide range of Earth’s natural systems, including permafrost thawing, plants blooming earlier across Europe, and lakes declining in productivity in Africa.
Cynthia Rosenzweig of NASA’s Goddard Institute for Space Science in New York and scientists at 10 other institutions have linked physical […]

The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming, scientists reported today in the journal Nature.
They also show that during that entire period […]

Research led by Iowa State University limnologist, or lake scientist, John Downing finds that ponds around the globe could absorb as much carbon as the world’s oceans.
Professor Downing found that constructed ponds and lakes on farmland in the United States bury carbon at a much higher rate than expected; as much as 20-50 times the […]

Over millions of years carbon dioxide levels in the atmosphere have been moderated by a finely-tuned natural feedback system — a system that human emissions have recently overwhelmed. A joint University of Hawaii / Carnegie Institution study published in the advance online edition of Nature Geoscience links the pre-human stability to connections between carbon dioxide […]

A much-discussed idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth’s protective ozone layer, new research concludes. The study, led by Simone Tilmes of the National Center for Atmospheric Research (NCAR), warns that such an approach might delay the recovery of the Antarctic ozone hole […]

Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases.
The Newcastle University team, led by Michael North, Professor of Organic Chemistry, has developed a highly energy-efficient method of converting waste carbon dioxide (CO2) into chemical compounds known as cyclic carbonates.
The team estimates that the technology has the potential to use […]

The old adage, “We are what we eat,” may be the latest recipe for success when it comes to curbing the perils of global climate warming. Despite the recent popular attention to the distance that food travels from farm to plate, aka “food miles,” Carnegie Mellon researchers Christopher L. Weber and H. Scott Matthews argue […]

There is no question that Al Gore’s 2006 documentary An Inconvenient Truth is a powerful example of how scientific knowledge can be communicated to a lay audience. What is up for debate is whether it accurately presents the scientific argument that global warming is caused by human activities. Climate change experts express their opinions on […]

The more you know the less you care — at least that seems to be the case with global warming. A telephone survey of 1,093 Americans by two Texas A&M University political scientists and a former colleague indicates that trend, as explained in their recent article in the peer-reviewed journal Risk Analysis.
“More informed respondents both […]

Satellite imagery from the University of Colorado at Boulder’s National Snow and Ice Data Center shows a portion of Antarctica’s massive Wilkins Ice Shelf has begun to collapse because of rapid climate change in a fast-warming region of the continent.
While the area of collapse involves 160 square miles at present, a large part of the […]

Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience.
Scripps Institution of Oceanography at UC San […]

An innovation called Carbon Hero may help reduce global warming by making people more aware of their carbon footprint. Regional prize winner in the 2007 European Satellite Navigation Competition, sponsored by ESA’s Technology Transfer Programme, the device uses satellite navigation technology to track journeys.
Concerned about global warming, many people are now looking for ways to […]

Now that scientists have reached a consensus that carbon dioxide emissions from human activities are the major cause of global warming, the next question is: How can we stop it? Can we just cut back on carbon, or do we need to go cold turkey? According to a new study by scientists at the Carnegie […]

A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen pollution.
Faster plant growth means the tropics will take in more carbon dioxide than previously thought, though long-term climate effects are unclear. Over […]

Political party affiliation has little bearing on the number of “green” actions people take, a new study by Porter Novelli and George Mason University shows. According to the survey of more than 11,000 American adults and nearly 1,000 of their children, Democrats and Republicans differ only slightly when it comes to taking actions to protect […]

Over the past 85 years, humans have helped shape California climate during certain seasons.
But that’s not necessarily good.
Recent research by scientists at the Lawrence Livermore National Laboratory, the University of California, Merced and the National Center for Atmospheric Research shows that California temperatures have jumped statewide by more than 2.1 degrees Fahrenheit between 1915 and […]

Increasing amounts of ice mass have been lost from West Antarctica and the Antarctic peninsula over the past ten years, according to research from the University of Bristol and published online this week in Nature Geoscience.
Meanwhile the ice mass in East Antarctica has been roughly stable, with neither loss nor accumulation over the past decade.
Professor […]
