Could wind farm installation deafen marine life?

Wind farms may be a vital source of green energy, but new research shows that the construction of off-shore wind farms could potentially be damaging the hearing of harbour seals and other marine life. Researchers at St. Andrews University in Scotland believe that there is cause for co

Prehistoric climate changes still detectable deep underground

It turns out that the steady dripping of water deep underground can reveal a surprising amount of information about the constantly changing cycles of heat and cold, precipitation and drought in the turbulent atmosphere above. As water seeps down through the ground it picks up minerals

US Exposure to Extreme Heat is on the Rise

U.S. residents’ exposure to extreme heat could increase four- to six-fold by mid-century, due to both a warming climate and a population that’s growing especially fast in the hottest regions of the country, according to new research.  The study, by researchers at the Natio

Can Ice Loss Affect Gravity?

A group of scientists, led by a team from the University of Bristol, has observed a sudden increase of ice loss in a previously stable region of Antarctica. The research is published today in Science. Using measurements of the elevation of the Antarctic ice sheet made by a suite of sa

National-scale effort addresses pollinator declines

A new White House plan to promote the health of bees and other pollinators calls for boosting research into ongoing population declines—and potential solutions. The plan, released yesterday, also recommends numerous measures to address growing concerns about the threat that bees, bird

How Genetics Can Save Endangered Mussels

<!– –> A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study. Local population losses in a river may not result in irreversible loss of mussel species; other

Bird populations responding to climate change

With puzzling variability, vast numbers of birds from Canada’s boreal forests migrate hundreds or thousands of miles south from their usual winter range. These so-called irruptions were first noticed by birdwatchers decades ago, but the driving factors have never been fully explained.

How Rivers Regulate Global Carbon Cycle

<!– –> Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the removal and long-term storage of carbon, including the world’s

World's largest herbivores in danger of extinction due to hunting and habitat loss

Many of the world’s largest herbivores — including several species of elephants, rhinoceroses, hippopotamuses and gorillas — are in danger of becoming extinct. And if current trends continue, the loss of these animals would have drastic implications not only for the species themselves

Urban development causes damage and loss of valuable ecosystems

All land is not created equal. Some ecosystems do triple duty in the benefits they provide to society. Massachusetts forests, for example, filter public drinking water while also providing habitat for threatened species and storing carbon to combat climate change. Ecologists and conse
