The Polyisocyanurate Insulation Manufacturers Association (PIMA) has released a new study that analyzes and quantifies the energy and environmental contribution of polyisocyanurate insulation (polyiso) over the past 25 years.
The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions.
First analyses of the longest sediment core ever collected on land in the Arctic, published this week in Science, provide dramatic, "astonishing" documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years.
The U.S. Fish and Wildlife Service Endangered Species Program has launched a new, web-based interactive map with information about endangered species success in every state.
Today at the Sewage and Water Board of New Orleans U.S. Environmental Protection Agency (EPA) Assistant Administrator Mathy Stanislaus announced that EPA is awarding $3 million to 15 grantees through the Environmental Workforce Development and Job Training (EWDJT) program.
Unhealthy air quality is predicted for the southern portions of Connecticut and Rhode Island, and the south coast of Massachusetts, including Cape Cod and the Islands, on Wednesday due to ground-level ozone.
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
GM recently added its 100th landfill-free facility – a parts distribution center in Lansing, Mich. It is a milestone in the company’s ongoing waste-reduction efforts.
American Seafoods Company LLC and Pacific Longline Company LLC have agreed to phase out the use of ozone depleting refrigerants, implement a comprehensive leak detection and repair program aboard a number of their vessels and pay a penalty to resolve federal Clean Air Act violations.
How do grasshoppers who are being frightened by spiders affect our ecosystem? In no small measure, say researchers at the Hebrew University of Jerusalem and at Yale University in the US.
A radical new approach to science and innovation is urgently needed to steer us within planetary boundaries and secure human wellbeing, fostering diverse types of innovation and empowering the grassroots creativity of poorer people, some experts say.
A Texas Tech University climate scientist said climate change is widely expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next 30 years.
The U.S. Environmental Protection Agency (EPA) has announced a new framework to help local governments meet their Clean Water Act obligations.
U.S. Environmental Protection Agency Regional Administrator Judith A. Enck met on Thursday, June 7, 2012 in New York City with representatives of local governments from Puerto Rico to discuss environmental challenges facing municipal governments in Puerto Rico, and explore solutions.
In an article published in the journal Nature Climate Change, researchers take a critical look at the various factors that have long been prime climate-change suspects. One in particular: The role of population growth.
The recent completion of a $52 million project to rid Roxana Marsh of contaminated sediment will speed the recovery of Indiana’s Grand Calumet River, marking a step forward for one of the Great Lakes’ most complex Area of Concern cleanups.
The oceans have warmed in the past 50 years, but not by natural events alone. New research shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.
Vast stores of carbon in U.S. forest soils could be released by rising global temperatures, according to a study by UC Irvine and other researchers in today's online Proceedings of the National Academy of Sciences in Washington, D.C.
In the journal Nature, paleoclimate researchers reveal that about 12-5 million years ago climate was decoupled from atmospheric carbon dioxide concentrations. In the last five million years, changes in ocean circulation allowed Earth's climate to become more closely coupled to changes in carbon dioxide concentrations in the atmosphere.
Communities of microbial organisms -- species such as nematodes, protists and fungi -- on beaches along the Gulf of Mexico changed significantly following the Deepwater Horizon oil spill in April 2010, research from the University of New Hampshire’s Hubbard Center for Genome Studies (HCGS) and partners found.
