The U.S. energy portfolio changes over time. Scientific and technologic advances related to hydraulic fracturing have dramatically increased the supply of U.S. oil and gas; because of this, a methane economy - in which natural gas provides the leading share of primary energy consumption - is now a possible scenario for U.S. energy development. In a report released by the American Geosciences Institute (AGI), the social, political, technical and environmental components of a methane economy are identified. The report also addresses how industry, government and the public might best work together to advance common energy goals.

Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the rise since 2004, around the time that the fracking industry began drilling natural gas wells in the state.
The researchers, publishing online April 9 in Environmental Health Perspectives, also found that buildings located in the counties where natural gas is most actively being extracted out of Marcellus shale have in the past decade seen significantly higher readings of radon compared with buildings in low-activity areas. There were no such county differences prior to 2004. Radon, an odorless radioactive gas, is considered the second-leading cause of lung cancer in the world after smoking.

The United States has one of the oldest, best-established park systems in the world. But what if those public lands -- mostly created to preserve scenic natural wonders -- are in the wrong place to conserve the lion’s share of the nation’s unique biodiversity? A new study published this week in the Proceedings of the National Academy of Sciences found exactly that. Existing “protected lands -- both federal and private -- poorly match the biodiversity priorities in the country,” say the researchers.

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
“If we can verify the methane emissions found by the satellite, and identify the various sources, then decision makers will have critical information for any actions they are considering,” says Gabrielle Pétron, a scientist from the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, working in NOAA’s Earth System Research Laboratory (ESRL) and one of the mission’s investigators. Part of President Obama’s recent Climate Action Plan calls for reductions in U.S. methane emissions. NOAA is the National Oceanic and Atmospheric Administration.

The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. Geological Survey.
The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data. Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.

The Sun undergoes a type of seasonal variability, with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research (NCAR). This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.

On World Health Day (7 April), European Commissioners Vytenis Andriukaitis and Neven Mimica highlight the importance of food safety, malnutrition, and fighting health threats both in the Union and in developing countries.
2015 is the European year for development (EYD). It is an opportunity to show how EU assistance is improving the lives of millions in developing countries; but also in Europe. Food safety, which is the theme of this year’s World Health Day, is a clear example of this.
Too often in Europe we take for granted that the food on our plates is safe. Europe should be proud that its 500 million consumers benefit from the highest food safety and health protection standards in the world, and that many other countries take them as the norm to be followed. However, we must not become complacent.
