Scientists at the University of East Anglia have found two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) in the atmosphere. The research, published today, comes after another four man-made gases were discovered by the same team in March. Scientists made the discovery by comparing today’s air samples with air collected between 1978 and 2012 in unpolluted Tasmania, and samples taken during aircraft flights.

How does the saying go? Only you can prevent forest fires, or only goats can prevent forest fires? You'll understand the confusion when you meet the Bay Area's latest fire prevention crews: goats. California is facing a forecast for what may be the worst fire season ever, thanks to drought conditions and a large buildup of tinder. Fire management professionals are working ahead of time to try to clear brush, high grass and other fire hazards, in the hopes of reducing the spread of the inevitable wildfires that are already streaking across the state. When it comes to brush clearance crews, it can be tough to find someone willing to do the job. It's backbreaking labor conducted in the hot sun, and it takes hours to make a dent in overgrown shrubs and brush, which are often filled with tangles of thorns and other unpleasant surprises. Brush clearance can get extremely expensive, and it requires constant maintenance. That's one reason why people have been turning to rental goats to clear brush and keep areas like road verges, medians and hillsides trimmed.

The U.S. Environmental Protection Agency is releasing the Clean Power Plan proposal today. This is the first attempt to cut carbon pollution from existing power plants, the single largest source of carbon pollution in the United States. According to the EPA, power plants account for roughly one-third of all domestic greenhouse gas emissions in the United States. While there are already standards for the level of arsenic, mercury, sulfur dioxide, nitrogen oxides, and particle pollution that power plants can emit, there are currently no national limits on carbon pollution levels.

After the US EPA announced their plan to cut US power plant emissions 30% by 2030, the European Union (EU) reacts, praising the Emission Performance Standard (EPS) for its vision while serving as a "positive signal" to other countries. "This proposed rule is the strongest action ever taken by the U.S. government to fight climate change," the EU's climate action commissioner, Connie Hedegaard said in a reaction statement. "If implemented as planned, this measure will help the country meet its 2020 emissions target."

El sector marÃtimo es una de las industrias menos reguladas en el mundo debido a las regulaciones obsoletas e internacionales que son difÃciles de aplicar a escala global. Y como los barcos entran en nuestros puertos cerca de casa, sus operaciones tienen el potencial de generar emisiones que forman smog y otros contaminantes que están vinculados a diversos problemas de salud en poblaciones susceptibles.
En un esfuerzo por combatir algunos de los contaminantes expulsados de las máquinas a diesel, la Agencia de Protección Ambiental de EE.UU. ha asignado más de un millón de dólares para ayudar a dos organizaciones especÃficas a reemplazan sus viejos motores con los modelos menos contaminantes.

Hurricanes with feminine names are likely to cause nearly three times as many deaths than storms with masculine names after new research found girl names are perceived as less threatening. A new University of Illinois study is warning to watch out for hurricanes with benign-sounding names like Dolly, Fay or Hanna because people in the path of these severe storms may take fewer protective measure, leaving them more vulnerable to harm.
