The densest waters of Antarctica have reduced dramatically over recent decades, in part due to man-made impacts on the climate, Australian scientists said Friday.
An electromagnetic signature called the Schumann Resonance could be used to study other planets besides Earth in the solar system and could shed light on how the solar system formed, according to a paper published in the Astrophysical Journal.
Changes in the ocean’s chemistry, as a result of increasing atmospheric carbon dioxide (CO2) levels, threaten marine plankton to a greater extent than previously thought, according to new research.
Scientists at University of California, Berkeley, will begin drilling into ancient sediments at the bottom of Northern California's Clear Lake to look at how today's plants and animals will adapt to climate change and increasing population.
Biodiversity loss could impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study by an international research team.
Researchers from UC San Diego have analyzed 50 plant studies on four continents to see how plants will respond to climate change in the future. Their study, published this week in the journal Nature, found that shifts in the timing of flowering and leafing in plants due to global warming appear to be much greater than estimated by warming experiments.
Intense development of the two largest natural gas fields in the continental United States is driving away some wildlife from their traditional wintering grounds, according to a study by the Wildlife Conservation Society.
Paper or plastic? Soon there will be just one choice at the 10 theme parks of SeaWorld Parks & Entertainment -- paper -- as the company eliminates plastic shopping bags within the next year. SeaWorld Parks & Entertainment will be the largest theme park operator to make this commitment.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have developed and launched new tools designed to test underutilized sites and contaminated land for solar and wind energy potential. The tools give local communities and landowners ways to evaluate sites for renewable energy potential without the need for technical expertise.
Every year nearly 7 million birds die as they migrate from the United States and Canada to Central and South America, according to a new University of Southern California (USC) study published in the journal PLoS ONE.
On the second anniversary of the Deepwater Horizon blowout, a national panel of researchers including University of Georgia marine scientist Samantha Joye is urging the federal government to reassess how it would respond to similar oil spills that might occur in the future.
The recent mild winter throughout much of the United States was a cause for celebration for many. However, butterfly aficionados shouldn't be joining in the celebration.
Forty years after a multi-year bi-partisan government commission recommended slowing U.S. population growth and eventually stabilizing, Americans still would like to see it happen, according to poll results to be released this weekend at the 2012 Earth Day Dallas festival.
The U.S. Environmental Protection Agency recently announced that it is requesting applications from states, municipalities, tribes, universities and nonprofit organizations for new projects to restore and protect the Great Lakes. EPA will distribute approximately $20 million through the Great Lakes Restoration Initiative grant program during Fiscal Year 2012.
Two years ago this week, oil began streaming from the seafloor into the Gulf of Mexico following the explosion of the Deepwater Horizon platform. All told, the disaster cost 11 lives, released 4.9 million barrels of crude oil, and caused still unspecified impacts to marine life and the Gulf economy.
A new analysis by the Australian Institute of Marine Science and the University of Western Australia concluded that in 2010, shark-related diving contributed $42.2 million ($73 million Fijian) to the economy of Fiji. Shark-diving operations generated $4 million that year for Fijian communities through salaries and local levies.
Heidelberg researchers have succeeded in unravelling the defense mechanisms of jellyfish. Scientists working with Prof. Dr. Thomas Holstein and Dr. Suat Özbek from the Centre for Organismal Studies (COS) of Heidelberg University, together with collaborators from the German Cancer Research Center (DKFZ), analyzed the proteome, or full set of proteins, of the stinging cells in the freshwater polyp Hydra.
The Andean Amazon is becoming a major frontier for new hydroelectric dams, but an analysis of the potential impacts of these planned projects suggests that there may be serious ecological concerns to take into account. The full report is published in the open access journal PloS ONE.
EPA has issued an enforcement order to AVX Corp. to implement the ongoing cleanup work at New Bedford Harbor, including dredging PCB-contaminated sediment from the Harbor and disposing the dredged sediment to an appropriately licensed off-site facility, into a confined aquatic disposal cell in the Harbor, and into confined disposal facilities to be built along the shoreline.
Officials from the U.S. Fish and Wildlife Service (FWS) are estimating that over 10,000 migrating birds have died so far this year because of reduced water flow to the Lower Klamath National Wildlife Refuge in Oregon and California. Officials say the final death toll may be close to 20,000 birds.
