Being in a warm room can make the idea of global warming seem more likely, according to researchers from the University of Chicago Booth School of Business and the Haas School of Business at University of California, Berkeley.
A new study finds that when people feel warmer—either because they are out in the hot sun or because they are in an overheated room—they believe in global warming more. The findings were published online Jan. 20 in the Journal of Personality and Social Psychology. (more…)
Fresh on the heels of a series of crippling floods that began in December 2010, and a small tropical cyclone, Anthony, this past weekend, the northeastern Australian state of Queensland is now bracing for what could become one of the largest tropical cyclones the state has ever seen.
The Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite, built and managed by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., captured this infrared image of Yasi on Jan. 31, 2011, at 6:29 a.m. PST (9:29 a.m. EST). The AIRS data create an accurate 3-D map of atmospheric temperature, water vapor and clouds, data that are useful to forecasters. The image shows the temperature of Yasi’s cloud tops or the surface of Earth in cloud-free regions. The coldest cloud-top temperatures appear in purple, indicating towering cold clouds and heavy precipitation. The infrared signal of AIRS does not penetrate through clouds. Where there are no clouds, AIRS reads the infrared signal from the surface of the ocean waters, revealing warmer temperatures in orange and red. (more…)
The temperatures of North Atlantic Ocean water flowing north into the Arctic Ocean adjacent to Greenland — the warmest water in at least 2,000 years — are likely related to the amplification of global warming in the Arctic, says a new international study involving the University of Colorado at Boulder.(more…)
To combat last year’s Deepwater Horizon oil spill, nearly 800,000 gallons of chemical dispersant were injected directly into the oil and gas flow coming out of the wellhead nearly one mile deep in the Gulf of Mexico. Now, as scientists begin to assess how well the strategy worked at breaking up oil droplets, Woods Hole Oceanographic Institution (WHOI) chemist Elizabeth B. Kujawinski and her colleagues report that a major component of the dispersant itself was contained within an oil-gas-laden plume in the deep ocean and had still not degraded some three months after it was applied.
While the results suggest the dispersant did mingle with the oil and gas flowing from the mile-deep wellhead, they also raise questions about what impact the deep-water residue of oil and dispersant—which some say has its own toxic effects—might have had on environment and marine life in the Gulf.

The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics.(more…)
EAST LANSING, Mich. — It’s commonly known, at least among microbiologists, that microbes have an additional option to living or dying — dormancy.
Dormant microbes are less like zombies and more like hibernating bears. What isn’t known, however, is how large numbers of dormant microorganisms affect the natural environments when they act as microbial seed banks. In the current issue of Nature Reviews: Microbiology, Jay Lennon, Michigan State University assistant professor of microbiology and molecular genetics, examines the cellular mechanisms that allow microbes to hibernate and addresses the implications they can have on larger ecosystems such as soil, oceans, lakes and the human body.

ANN ARBOR, Mich.— As a child in Mali, Abdrahamane Traoré often did his homework by the sooty, dim light of a kerosene lamp.
As an adult in Michigan, he sometimes has a tough time reaching his family back home. Traoré’s mother must walk to a neighboring village to keep a cell phone charged. (more…)
