Mapping Alaska and the Arctic: Researcher Available to Discuss Project Announced Today by White House

Michael Willis is an earth and atmospheric sciences research associate at Cornell University and a member of the research team for ArcticDEM – a project announced today by the White House that will develop a high-resolution topographic map of the Arctic that, for the first time, will provide consistent coverage of the entire region to better monitor the effects of climate change. He is available to answer questions about the project, his work and the Arctic region in general.

Saving Oysters by Digging Up Their Past

Restoring oyster reefs is not an easy task, but by digging deep and examining centuries-old reefs, marine restoration professionals may stand a better chance at bringing oysters back, said a new Cornell University and Paleontological Research Institution (PRI) study published in the August issue of the Journal of Shellfish Research.

Columbia Engineers Develop New Approach to Modeling Amazon Seasonal Cycles

GentineAmazonfoglbl-gov.jpg

Columbia engineers have developed a new approach, opposite to climate models, to correct inaccuracies using a high-resolution atmospheric model that more precisely resolves clouds and convection and parameterizes the feedback between convection and atmospheric circulation. The new simulation strategy paves the way for better understanding of the water and carbon cycles in the Amazon, enabling researchers to learn more about the role of deforestation and climate change on the forest.” (PNAS Online Early Edition 8/31)

Quantifying the Impact of Volcanic Eruptions on Climate

Sarychev_2009.png

Large volcanic eruptions inject considerable amounts of sulphur in the stratosphere which, once converted into aerosols, block sun rays and tend to cool the surface of the Earth down for several years. An international team of researchers has just developed a method, published in Nature Geoscience, to accurately measure and simulate the induced drop in temperature.

Capturing and Converting Carbon Dioxide in a Single Step

Turning carbon dioxide from certain power plants into a more valuable chemical would reduce emissions while creating a revenue return. Scientists at the University of Pittsburgh derived a metal-free catalyst that does the trick without the need for expensive, extreme conditions.

MSU Faculty Research Shows California Levees’ Vulnerability

Farshid_Vahedifard_MSU.jpg

With the ongoing extreme drought in California posing a threat to the state’s levee systems, there is an urgent need to invest in research regarding the vulnerabilities of critical infrastructure under extreme climatic events. Mississippi State University Assistant Professor of Civil and Environmental Engineering Farshid Vahedifard and his coauthors warn that current drought conditions pose “a great risk to an already endangered levee system” in a letter published Aug. 21 in Science magazine.

Changing climate conditions have caused dramatic changes in groundwater levels. This study aimed at understanding the changes in soil wetting and drying that occur as snow melts in mountainous, snow-packed regions. The study examined subsurface water content levels in the Sierra Nevada mountains in California. In these regions, soils do not freeze during the winter and remain wet beneath the snowpack.

Carbon Number Crunching

A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.

‘Diamonds From the Sky’ Approach Turns CO₂ Into Valuable Products

article637961.image1.jpg

Finding a technology to shift carbon dioxide (CO2), the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products. They will present the research at the 250th National Meeting & Exposition of the American Chemical Society.

Change in Process of Disinfecting Spinach, Salad Greens Could Reduce Illness Outbreaks

Cross contamination in commercial processing facilities that prepare spinach and other leafy greens for the market can make people sick. But researchers are reporting a new, easy-to-implement method that could eliminate or reduce such incidences. The scientists will present their work at the 250th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

New Technology Can Expand LED Lighting, Cutting Energy Use and Greenhouse Gas Emissions

article637649_1.jpg

Highly efficient, light-emitting diodes (LEDs) could slash the world’s electricity consumption. They are already sold in stores, but are expensive, and many of them give off “harsh” light. But researchers will report today that they have developed a less expensive, more sustainable white LED with a warm glow. The scientists will discuss their research at the 250th National Meeting & Exposition of the American Chemical Society.
