The federal and state natural resource trustees estimate that the spill killed 6,849 birds, affected 14 to 29 percent of the herring spawn that winter, oiled 3,367 acres of shoreline habitat and resulted in the loss of more than one million recreational user-days. A result of a multi-governmental effort by federal and state agencies, and municipal governments, the settlement is expected to fully compensate (in addition to previously reimbursed costs) for the natural resources and other damages and costs resulting from the spill.
Deforestation in the rainforests of West Africa reduces rainfall over the rest of the forest, according to new University of Leeds research published in Geophysical Research Letters. The study shows that changing land use from forest to crop land reduces rainfall over neighboring trees by about 50 percent due to changes in the surface temperature, which affects the formation of rain clouds.
The planet’s deep oceans at times may absorb enough heat to flatten the rate of global warming for periods of as long as a decade even in the middle of longer-term warming, according to a new analysis led by the National Center for Atmospheric Research (NCAR).
U.S. President Barack Obama announced diplomatic measures the United States will take against Iceland to condemn its whaling activities.
A team of researchers from the Georgia Institute of Technology is using the Aquarius underwater laboratory off the coast of Florida to study how the diversity of seaweed-eating fish affects endangered coral reefs. The research mission, which began Sept. 13, may provide new information to help scientists protect and even restore damaged coral reefs in the Caribbean.
Farms of “underwater windmills” could affect how sand moves around our coastal seas, affecting beaches, sand banks and ultimately the risk of flooding, according to Bangor University oceanographer Dr. Simon Neill.
Restoring and preserving dryland forests and planting more trees to provide food, fodder and fertilizer on small farms are critical steps toward preventing the recurrence of the famine now threatening millions of people in the Horn of Africa, according to forestry experts from the CGIAR Consortium.
The past decade has seen 77,951 fires burn about 6.7 million acres in the United States. One condition that facilitates the spread of wildfires is invasive plant species. Nonnative weeds can modify the vegetation of a landscape and provide a source of fuel that did not previously exist.
Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research from Carnegie's Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere.
Stanford researchers have gotten a glimpse into an uncertain future where increasing levels of carbon dioxide in the Earth's atmosphere will lead to higher levels in the ocean as well, leaving the water more acidic and altering underwater ecosystems.
La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
University of Iowa researchers have found high levels of toxic polychlorinated biphenyls (PCBs) in the deep sediments lining the Indiana Harbor and Ship Canal (IHSC) in East Chicago, Ind.
The Florida Fish and Wildlife Conservation Commission recently partnered with Fishing for Energy to remove derelict stone crab traps from the marine environment near Everglades City, Fla., making it the second location in Florida to join the unique partnership.
Boston University researchers have estimated that even if international efforts to limit temperature increases to 2 degrees Celcius, mean global temperatures will continue to be extreme.
Restoring prairies to their native vegetation can be approached from several directions. Managers might eliminate invasive plants through use of herbicides, encourage growth of native species through seeding, or manipulate conditions to favor native species.
Trees can reveal key information about fire events, and some trees have a lot to tell — one tree researchers examined endured 14 separate fires through its lifetime.
New research suggests that ancient sharks bred in the shallows of freshwater lakes, forming nurseries for their hatchlings.
The research, conducted by the U.S. Army Engineer Research and Development Center (ERDC), focused primarily on the gathering of root characterization and site conditions through fieldwork, and modeling of single, living trees for both slope stability analyses and seepage analyses.
The percent of land area experiencing exceptional drought reached record levels in August in three U.S. states – Texas, Oklahoma and Kansas – amid new concerns about how long the conditions may persist, an official with the National Drought Mitigation Center at the University of Nebraska-Lincoln said.
Recent heavy rain and flooding has increased the danger of landslides on moderate to steep slopes, according to scientists in the Bureau of Topographic and Geologic Survey in the Department of Conservation and Natural Resources (DCNR).
