The pipes that rise from oil fields, topped with burning flames of natural gas, waste fossil fuels and dump carbon dioxide into the air. In new work, researchers have identified the structure of a catalytic material that can turn methane into a safe and easy-to-transport liquid. The insight lays the foundation for converting excess methane […]

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 […]

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 […]

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 […]

A new, high-resolution, interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren’t all where we thought.
“For example, we’ve been attributing too many emissions to the northeastern United States, and it’s looking like the southeastern U.S. is a much larger source than we had estimated previously,” says Kevin Gurney, […]

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 […]

The last fish you ate probably came from the Bering Sea.
But during this century, the sea’s rich food web — stretching from Alaska to Russia — could fray as algae adapt to greenhouse conditions.
“All the fish that ends up in McDonald’s, fish sandwiches — that’s all Bering Sea fish,” said USC marine ecologist Dave Hutchins, […]

Researchers led by biologist Jeffrey Chambers of Tulane University have determined that the losses inflicted by Hurricane Katrina on Gulf Coast forest trees are enough to cancel out a year’s worth of new tree biomass (trunks, branches and foliage) growth in other parts of the country.
"The carbon that will be released as these trees decompose […]
