LOS ALAMOS, N.M., March 15, 2016—A new study of permafrost has found that the ice wedges forming the prevalent honeycomb pattern across the tundra appear to be melting rapidly across the Arctic, changing the hydrology of the region and accelerating the release of greenhouse gases with major implications for global warming. While the gradual warming

USGS scientists, in collaboration with researchers at the University of Minnesota and University of Alaska Fairbanks, have mapped belowground permafrost in areas of Alaska that have been affected by wildfire, years-to-decades after the fires occurred. “There has been global concern for many years about the effects of the warming climate on high-latitude permafrost and its

Mankind must learn to live with wildland fires by reintegrating fire as a vital landscape process and building communities that are resilient to fire, according to professor Mark Cochrane, a wildfire expert and senior scientist at the Geospatial Sciences Center of Excellence. In 2014, the federal government addressed the complexities of managing wildfires through the

UNIVERSITY PARK, Pa.—Extreme weather events like floods, heat waves and droughts can devastate communities and populations worldwide. Recent scientific advances have enabled researchers to confidently say that the increased intensity and frequency of some, but not all, of these extreme weather events is influenced by human-induced climate change, according to an international National Academies of

RIVERSIDE, Calif.—When plant matter burns, it releases a complex mixture of gases and aerosols into the atmosphere. In forests subject to air pollution, these emissions may be more toxic than in areas of good air quality, according to a new study by the University of California, Riverside and the U.S. Forest Service’s Pacific Southwest Research

The House of Representatives today unanimously approved bipartisan legislation to address the rising costs of disasters in the United States, reduce the toll of future losses, and improve the efficiency and effectiveness of the Federal Emergency Management Agency’s (FEMA) disaster assistance capabilities and programs. The FEMA Disaster Assistance Reform Act of 2015 (H.R. 1471) was

Environmental scientists at the University of Virginia have found that surface ozone, an abundant chemical known to be toxic to many species of vegetation and to humans, does not necessarily inhibit the productivity of natural ecosystems. “This is a rare piece of good news in the ozone and ecology story,” said Manuel Lerdau, an ecologist

The Aliso Canyon natural gas well blowout, first reported on Oct. 23, 2015, released over 100,000 tons of the powerful greenhouse gas methane before the well was sealed on Feb. 11, according to the first study of the accident published today in the journal Science. The results confirm that Aliso Canyon is the largest methane

BOULDER—Sweltering heat waves that typically strike once every 20 years could become yearly events across 60 percent of Earth’s land surface by 2075, if human-produced greenhouse gas emissions continue unchecked. If stringent emissions-reductions measures are put in place, however, these extreme heat events could be reduced significantly. Even so, 18 percent of global land areas

The EEA report ‘Mapping and assessing the condition of Europe’s ecosystems: progress and challenges’ gives a snapshot of current ecosystem health in Europe. It identifies key gaps in data which are essential to properly assess the health of Europe’s many ecosystems.
