An innovative method for stripping greenhouse gases such as carbon dioxide from industrial emissions is potentially cheaper and more efficient than current methods, according to a United States patent based on research by Dr. Jason E. Bara, assistant professor of chemical and biological engineering at The University of Alabama.
When the carbon dioxide content of the atmosphere rises, the Earth not only heats up, but extreme weather events, such as lengthy droughts, heat waves, heavy rain and violent storms, may become more frequent.
With sea ice at its lowest point in 1,500 years, how might ecological communities in the Arctic be affected by its continued accelerating melting over the next decades? Penn State Professor of Biology Eric Post and an international team of scientists tackle this question by examining relationships among algae, plankton, whales and terrestrial animals such as caribou, arctic foxes and walrus; as well as the effects of human exploration of previously inaccessible parts of the region.
The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate scientists warn that the likely rate of change over the next century will be at least 10 times quicker than any climate shift in the past 65 million years.
With the “green” reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse gases linked to global climate change. Their study, showing that more methane than previously believed bubbles out of the water behind small dams, appears in ACS’ journal Environmental Science & Technology.
Researchers reviewed the likelihood of continued changes to the terrestrial climate, including an analysis of a collection of 27 climate models. If emissions of heat-trapping gases continue along the recent trajectory, 21st century mean annual global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during 2046 to 2065 and 7.2 °F (4 °C) during 2081-2100. If warming occurs at this pace, it will probably be the most rapid large climate change in the last 65 million years.
A technique for trapping the greenhouse gas carbon dioxide deep underground could at the same be used to release the last fraction of natural gas liquids from ailing reservoirs, thus offsetting some of the environmental impact of burning fossil fuels. So says a paper to be published in the peer-reviewed International Journal of Oil, Gas and Coal Technology.
A regional experiment to see if carbon dioxide can be stored safely and permanently underground has begun, Montana State University scientists and their partners announced Friday, July 26.
Most big data centers, the global backbone of the Internet, could slash their greenhouse gas emissions by 88 percent by switching to efficient, off-the-shelf equipment and improving energy management, according to new research.
NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world.
