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.
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.
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.
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.
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.
A Northbridge, Mass., company that produces hard foam products has agreed to strictly limit air pollution emissions from its manufacturing facility and pay a $127,500 penalty to settle claims by the Environmental Protection Agency and the Department of Justice that it violated federal Clean Air laws.
EPA recently announced that all ‘flexible permit’ companies in Texas have agreed to apply for approved air permits, helping to achieve clean air in the state and providing for regulatory certainty.
An estimated two billion people in the developing world heat and cook with a biomass fuel such as wood, but the practice exposes people – especially women – to large doses of small-particle air pollution, which can cause premature death and lung disease.
Researchers have discovered a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems.
