Wind turbines may have beneficial effects for crops
December 9, 2016 05:15 PM - Iowa State University

A multi-year study led by an Iowa State University scientist suggests the turbines commonly used in the state to capture wind energy may have a positive effect on crops.

Gene Takle, a Distinguished Professor of agronomy and geological and atmospheric sciences, said tall wind turbines disbursed throughout a field create air turbulence that may help plants by affecting variables such as temperature and carbon dioxide concentrations.

Against the Tide: A Fish Adapts Quickly to Lethal Levels of Pollution
December 9, 2016 07:24 AM - Kat Kerlin, UC Davis

Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 in the journal Science. 

While environmental change is outpacing the rate of evolution for many other species, Atlantic killifish living in four polluted East Coast estuaries turn out to be remarkably resilient. These fish have adapted to levels of highly toxic industrial pollutants that would normally kill them.

Can Road Salt Change Sex Ratios in Frog Populations?
November 29, 2016 07:34 AM - Kevin Denny, Yale School of Forestry & Environmental Studies

Naturally occurring chemicals found in road salts commonly used to de-ice paved surfaces can alter the sex ratios in nearby frog populations, a phenomenon that could reduce the size and viability of species populations, according to a new study by scientists at Yale and Rensselaer Polytechnic Institute (RPI).

Concrete jungle functions as carbon sink
November 22, 2016 07:03 AM - UCI News

Cement manufacturing is among the most carbon-intensive industrial processes, but an international team of researchers has found that over time, the widely used building material reabsorbs much of the CO2 emitted when it was made.

Ammonia-rich bird poop cools the atmosphere
November 21, 2016 07:12 AM - Colorado State University

It turns out bird poop helps cool the Arctic.

That’s according to new research from Colorado State University atmospheric scientists, who are working to better understand key components of Arctic climate systems.

Biodiversity needs citizen scientists
November 3, 2016 07:49 PM - Linda See, IIASA

Could birdwatching or monitoring tree blossoms in your community make a difference in global environmental research? A new study says yes: citizen scientists have a vital role to play.

Citizen scientists are already providing large amounts of data for monitoring biodiversity, but they could do much more, according to a new study published in the journal Biological Conservation, which suggests that citizen science has the potential to contribute much more to regional and global assessments of biodiversity. Citizen scientists are regular people who provide data or input to science, for example by monitoring species in their community or examining satellite imagery for evidence of deforestation or land use change. 

“Citizen scientists are already contributing enormously to environmental science,” says IIASA researcher Linda See. “For example, a huge amount of species occurrence data is provided by members of the interested public. The question we addressed was, where are citizens contributing and where are they not, and how can we draw on this phenomenon to help fill the gaps in science?”

Food and Energy Demand Drives 58 Percent Decline in Global Wildlife Populations
October 28, 2016 07:16 AM - Lorin Hancock, World Wildlife Fund

Global populations of vertebrates -- mammals, birds, reptiles, amphibians, and fish -- have declined by 58 percent between 1970 and 2012, states a new report from World Wildlife Fund (WWF). Animals living in the world’s lakes, rivers, and freshwater systems have experienced the most dramatic population declines, at 81 percent. Because of human activity, the report states that without immediate intervention global wildlife populations could drop two-thirds by 2020.

The buzz about edible bugs: Can they replace beef?
October 27, 2016 07:16 AM - American Chemical Society

The idea of eating bugs has created a buzz lately in both foodie and international development circles as a more sustainable alternative to consuming meat and fish. Now a report appearing in ACS’ Journal of Agricultural and Food Chemistry examines how the nutrients — particularly iron — provided by grasshoppers, crickets and other insects really measures up to beef. It finds that insects could indeed fill that dietary need.

Globally Averaged CO2 Levels Reach 400 parts per million in 2015
October 25, 2016 07:11 AM - World Meteorological Organization

Globally averaged concentration of carbon dioxide in the atmosphere reached the symbolic and significant milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016 on the back of the very powerful El Niño event, according to the World Meteorological Organization's annual Greenhouse Gas Bulletin.

Researchers use 'robomussels' to monitor climate change
October 18, 2016 07:07 AM - Northeastern University

Tiny robots have been helping researchers study how cli­mate change affects bio­di­ver­sity. Devel­oped by North­eastern Uni­ver­sity sci­en­tist Brian Hel­muth, the “robo­mus­sels” have the shape, size, and color of actual mus­sels, with minia­ture built-in sen­sors that track tem­per­a­tures inside the mussel beds.
