For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980.
As a result of the fracking revolution, North America has overtaken Saudi Arabia as the world's largest producer of oil and gas. This, despite endless protests from environmentalists. But does drilling for natural gas really cause pollution levels to skyrocket?
In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. The report, published in the journal Proceedings of the Royal Society B (Biological Sciences), offers key data for setting management and conservation targets to protect and preserve fragile coral reefs.
With global production of plastic exceeding 280 metric tons every year, a fair amount of the stuff is bound to make its way to the natural environment. However, until now researchers haven't known whether ingested plastic transfers chemical additives or pollutants to wildlife.
A new study, led by a University of Southampton scientist, highlights the potential for fish communities in marine reserves to resist climate change impacts better than communities on fished coasts.
New insights into the growth dynamics of minuscule marine organisms could help put the study of Earth’s climate, both present and prehistoric, on a more solid footing.
The Gulf of Mexico Research Initiative (GoMRI) announced today that it plans to award up to $105 million to support research consortia investigating the effect, and the potential associated impact, of hydrocarbon releases on the environment and public health, as well as to develop improved spill mitigation, oil detection, characterization, and remediation technologies.
A new estimate of bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States. The estimate, published in an article in BioScience, used sophisticated statistical techniques to infer the probable number of bat deaths at wind energy facilities from the number of dead bats found at 21 locations, correcting for the installed power capacity of the facilities.
Devoted to an assessment of climate change effects on ecosystems and the consequences for people, the November issue of the Ecological Society of America's journal "Frontiers in Ecology and the Environment" contains papers from a diverse group of more than 50 ecological scientists, including UC Santa Barbara's Joshua Schimel, professor and chair of the Environmental Studies Program.
Growth in offshore wind generation is expected to play a major role in meeting carbon reduction targets around the world, but the impact of construction noise on marine species is yet unknown. A group of scientists from the United Kingdom and the United States have developed a method to assess the potential impacts of offshore wind farm construction on marine mammal populations, particularly the noise made while driving piles into the seabed to install wind turbine foundations. Their work is published in the November issue of Environmental Impact Assessment Review.
