Using government-supplied measurements, the researchers found concentrations of fine particles in Ulaanbaatar’s air were more than seven times the level considered safe by the World Health Organization
Researchers at the University of California, Riverside along with their research partners received a $1.2 million grant from the Department of Energy to study and evaluate technologies that provide feedback to drivers so they can cut harmful emissions and reduce fuel use by up to 30 percent.
Their estimate, reported this week in the online edition of the Proceedings of the National Academy of Sciences, is based on a signal sent across the Pacific Ocean when operators of the damaged reactor had to resort to cooling overheated fuel with seawater.
Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature.
As consumers stay focused on keeping cool during the hottest months of the year, they may fall victim to some of the myths that may be giving electricity customers the wrong idea about how to curb their electricity consumption and save money on their monthly bills.
These findings point to climate change and variability working together equally to accelerate the observed sea ice loss during the late 20th century.
New computer modeling work shows that by 2100, if society wants to limit carbon dioxide in the atmosphere to less than 40 percent higher than it is today, the lowest cost option is to use every available means of reducing emissions.
Writing in the journal Annals of Botany, Professor Douglas Kell argues that developing crops that produce roots more deeply in the ground could harvest more carbon from the air, and make crops more drought resistant, while dramatically reducing carbon levels.
Residents in the Midwest awoke to the highest mold count for the season after a night of torrential rain and lightening strikes. An official air alert was issued by Joseph Leija, MD, allergist who performs the official allergy count for the Midwest for the National Allergy Bureau.
Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.
While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming.
Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced that Dow Chemical Company has agreed to pay a $2.5 million civil penalty to settle alleged violations of the Clean Air Act, Clean Water Act and the Resource Conservation and Recovery Act (RCRA) at its chemical manufacturing and research complex in Midland, Mich.
U.S. District Court Judge Adalberto Jordan sentenced Brendan Clery, 34, to 18 months in prison and ordered him to pay a $10,000 criminal fine and forfeit illegal proceeds in the amount of $935,240.
The U.S. Environmental Protection Agency (EPA) recently proposed standards to reduce harmful air pollution from oil and gas drilling operations.
A record 6.86 inches of rain that fell Saturday, July 23, and 4.37 more on Wednesday, July 27, is causing rivers to crest, blocking roads, stopping public transportation, causing power outages and flooding basements. Chicago is close to breaking an 1871 weather record for number of rainy days in July.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced a settlement with Caterpillar Inc. to resolve alleged Clean Air Act violations for shipping more than 590,000 highway and non-road diesel engines without the correct emissions controls.
Senior energy executive Karl W. Miller is a major supporter in establishing a comprehensive energy plan for the U.S.
Greenhouse gas (GHG) emissions have been reduced by an accumulated 5.7 million metric tonnes (mt) in Mexico City since it began implementing its Green Plan in 2008, the Mexico City government recently announced.
A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of carbon dioxide (CO2) change during the past decade, according to a new study led by NOAA and published today in the online edition of Science.
