PULLMAN, Wash. – Washington State University researchers have developed a soy-based air filter that can capture toxic chemicals, such as carbon monoxide and formaldehyde, that current air filters can’t.
AMHERST, Mass. – Results of a new study by researchers at the Northeast Climate Science Center (NECSC) at the University of Massachusetts Amherst suggest that temperatures across the northeastern United States will increase much faster than the global average, so that the 2-degrees Celsius warming target adopted in the recent Paris Agreement on climate change will be reached about 20 years earlier for this part of the U.S. compared to the world as a whole.
The mineral erionite is considered to be highly carcinogenic and is on the World Health Organisation's list of substances that cause cancer. A few years ago, an entire village in Turkey actually had to be moved, because the substance was very common in the surrounding area and every second inhabitant died of a particular type of cancer caused by breathing in erionite particles. Up to now it has been thought that iron as a constituent element of the mineral erionite is the reason for the carcinogenic effect. However, mineralogists of Friedrich Schiller University Jena (Germany), together with colleagues from the University of Modena (Italy), have discovered that this metal does not even appear in the crystal structure of erionite.
A special issue of the journal Energy Technology details the latest advances in pyrolysis technologies for converting biomass into fuels, chemicals and fertilizers.
Two pyrolysis experts are guest editors of the issue: Robert C. Brown, the director of Iowa State University’s Bioeconomy Institute, an Anson Marston Distinguished Professor in Engineering and the Gary and Donna Hoover Chair in Mechanical Engineering; and George Huber, the University of Wisconsin-Madison’s Harvey D. Spangler Professor of Chemical and Biological Engineering.
The US National Academies of Sciences, Engineering, and Medicine has proposed a new framework for US agencies to use to estimate the 'social cost of carbon dioxide' emissions. Myles Allen, Professor of Geosystem Science at the Environmental Change Institute, helped compile the report which will strengthen the scientific basis and provide greater transparency for US climate policy.
The U.S. tosses a staggering $161 billion worth of food every year. While numerous efforts are underway to address that problem, they are taking place mostly at the local level or in the business sector. While that is necessary, national- and international-level policy has a role to play as well. And that is one area in which Europe is far ahead.
EVANSTON - Chad A. Mirkin, the George B. Rathmann Professor of Chemistry in the Weinberg College of Arts and Sciences and director of the International Institute for Nanotechnology at Northwestern University, has been awarded the 2016 Dickson Prize in Science.
The idea of climate change causing a major ocean circulation pattern in the Atlantic Ocean to collapse with catastrophic effects has been the subject of doomsday thrillers in the movies, but in climate forecasts, it is mostly regarded as an extreme longshot.
Now a new paper based on analysis done at a group of research centers including Scripps Institution of Oceanography at the University of California San Diego shows that climate models may be drastically underestimating that possibility. A bias in most climate models exaggerates the stability of the pattern, called the Atlantic meridional overturning circulation (AMOC), relative to modern climate observations. When researchers removed the bias, and re-ran simulations, the result prompted them to predict a collapse of the circulation at some point in the future, setting off large-scale cooling in the north Atlantic. The collapse would stop the AMOC, which delivers warm surface water toward Greenland then sinks as it cools and flows back toward the equator closer to the seafloor.
OVER THE PAST several months, scientists working in Antarctica have been watching—with a mixture of professional fascination and personal horror—a fissure growing in the continent’s fourth-largest ice shelf. Since last November, the crack has lengthened by some 90 miles. It has 13 miles more before it rends completely, and a chunk of ice the size of Delaware goes bobbing into the Weddell Sea. The calving chunk could be a sign that the entire Larsen C ice shelf—nearly twice the size of Massachusetts—is breaking apart.
The Canadian oil sands are one of the world’s largest sources of climate pollution and America’s biggest source of imported oil. And they may be about to go bust.
Canada’s oil sands, also known as tar sands, are the world’s fourth-largest reserve of crude oil. Mining them unleashes massive volumes of carbon dioxide into the atmosphere, easing the way for global warming to blow past 2°C (3.6°F) — levels considered “dangerous” under the Paris Climate Agreement.
