A new study shows that reaching the 3 energy-related objectives proposed by the United Nations in their Sustainable Energy for All (SE4All) initiative, launched in 2011, would reduce emissions of greenhouse gases that contribute to climate change and, in combination with other measures, could help keep global temperature rise from exceeding the internationally agreed target level of 2 C.
Applying its atmospheric expertise to solar energy, the National Center for Atmospheric Research (NCAR) is spearheading a three-year, nationwide project to create unprecedented, 36-hour forecasts of incoming energy from the Sun for solar energy power plants.
The commitment to reduce greenhouse gas emissions should be allocated based on countries' historic responsibility for the emissions. This logic was recognized early on in climate negotiations. But the countries are still disputing how it should be interpreted and applied.
The U.S. Environmental Protection Agency (EPA) today announced the nominations for the 2013 Presidential Green Chemistry Challenge Awards for companies and institutions that can design chemicals or a new product that help protect public health and the environment.
Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in charge of the activity and its goals. New modeling work shows that if a powerful coalition ever decided to deploy a geoengineering system, they would have incentive to exclude other countries from participating in the decision-making process.
The robustness of food webs of Arctic and Antarctic ecosystems has been compared for the first time, revealing that global warming can affect the biodiversity of these ecosystems in different ways despite the similarities between them.
Today the Solar Energy Industries Association (SEIA) launched the U.S. Solar Heating and Cooling Alliance (SHC Alliance). The Alliance will focus on growing the solar heating and cooling market through reducing barriers and advocating for policies on the federal, state and local levels.
