Drought shriveled crops in the Midwest, massive wildfires raged in the West and East Coast cities sweltered. The summer of 2012 was a season of epic proportions, especially July, the hottest month in the history of U.S. weather record keeping.
The new study by Prof. Sarah Kang from Ulsan National Institute of Science and Technology (UNIST), showed that the ozone depletion over the South Pole has affected the extreme daily precipitation in the austral summer, for December, January, and February (DJF). This work was published in the journal Geophysical Research Letter. (Title: “Modeling evidence that ozone depletion has impacted extreme precipitation in the austral summer”, Vol. 40, 1-6, doi:10.1002/grl.50796, 2013)
CO2 Solutions Inc., an innovator in the field of enzyme-enabled carbon capture technology, today announced that it has met and exceeded the first two technical performance milestones for its Alberta Oil Sands project. The Company demonstrated its patented carbon capture technology is at least one-third less expensive than existing carbon capture technology in terms of energy consumption, and can withstand the rigors of industrial application.
The best real estate for coral reefs over the coming decades will no longer be around the equator but in the sub-tropics, new research from the University of Bristol suggests.
New research by Scripps Institution of Oceanography, UC San Diego climate scientists attributes the attenuation of a worldwide temperature increase to a cooling of eastern Pacific Ocean waters, one that counteracts the warming effect of greenhouse gases.
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.
