Soot packs a punch on Tibetan Plateau’s climate

RICHLAND, Wash. — In some cases, soot — the fine, black carbon silt that is released from stoves, cars and manufacturing plants — can pack more of a climatic punch than greenhouse gases, according to a paper published in the journal Atmospheri…

Global warming may reroute evolution

ANN ARBOR, Mich.—Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.

War, plague no match for deforestation in driving CO2 buildup

Stanford, CA — Genghis Khan and his Mongol hordes had an impact on the global carbon cycle as big as today’s annual demand for gasoline. The Black Death, on the other hand, came and went too quickly for it to cause much of a blip in the global car…

Virus killer gets supercharged

A simple technique to make a common virus-killing material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li.
Rather than trying to turn the process into profit, the researchers have put it …

Carbon swap bank to beat climate change

Australian researchers have suggested that nations should abandon the concept of carbon emissions trading in favor of a carbon swap bank that might lead to genuine reductions in the amount of carbon dioxide greenhouse gas entering the atmosphere and…

‘Greener’ climate prediction shows plants slow warming

GREENBELT, Md. — A new NASA computer modeling effort has found that additional growth of plants and trees in a world with doubled atmospheric carbon dioxide levels would create a new negative feedback — a cooling effect — in the Earth’s c…

Rewarding eco-friendly farmers can help combat climate change

COLLEGE PARK, Md. — Financially rewarding farmers for using the best fertilizer management practices can simultaneously benefit water quality and help combat climate change, finds a new study by the University of Maryland’s Center for Integrat…

Venus holds warning for Earth

A mysterious high-altitude layer of sulphur dioxide discovered by ESA’s Venus Express has been explained. As well as telling us more about Venus, it could be a warning against injecting our atmosphere with sulphur droplets to mitigate climate ch…

ORNL scientists crack materials mystery in vanadium dioxide

OAK RIDGE, Tenn., Nov. 23, 2010 — A systematic study of phase changes in vanadium dioxide has solved a mystery that has puzzled scientists for decades, according to researchers at the Department of Energy’s Oak Ridge National Laboratory.

Extending the life of oil reserves

A research team led by the University of Bristol has used STFC’s ISIS Neutron Source to come up with a new way to treat carbon dioxide (CO2), so that it can be used in efficient and environmentally friendly methods for extracting oil. These new CO2 …

New research changes understanding of C4 plant evolution

Frostburg, Md. (November 15, 2010) — A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence cas…

Primordial dry ice fuels comet jets

COLLEGE PARK, Md. — One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-led EPOXI mission as it zipped past comet Hartley 2 last week is that dry ice is the ‘jet’ fuel for this comet…

Scrambling for climate change solutions

The food industry generates a lot of waste products, but one of these, eggshells, could help combat climate change, according to research published in the International Journal of Global Warming this month.

Green Carbon Center takes all-inclusive view of energy

Rice University has created a Green Carbon Center to bring the benefits offered by oil, gas, coal, wind, solar, geothermal, biomass and other energy sources together in a way that will not only help ensure the world’s energy future but also provide …

Carbon dioxide controls Earth’s temperature

NEW YORK — Water vapor and clouds are the major contributors to Earth’s greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet’s temperature ultimately depends on the atmospheric level of carbon dioxide.
The s…
