Manmade pollutants may be driving Earth's tropical belt expansion
Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows. (2012-05-17)

Biodiversity loss ranks with climate change and pollution in terms of impacts to environment
A recent study published by an international research team working at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) has found that loss of biodiversity impacts the environment as significantly as climate change and pollution. (2012-05-10)

UGA study finds in extinction risk, there's not always safety in numbers
A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship. (2012-05-09)

Support for climate change action drops, Stanford poll finds
Americans' support for government action on global warming remains high but has dropped during the past two years, according to a new survey by Stanford researchers in collaboration with Ipsos Public Affairs. (2012-05-09)

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study. (2012-05-08)

Scientists core into California's Clear Lake to explore past climate change
University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population. (2012-05-04)

Ecosystem effects of biodiversity loss could rival impacts of climate change, pollution
Loss of biodiversity appears to impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study from an international research team. (2012-05-03)

Global warming: New research emphasizes the role of economic growth
It's a message no one wants to hear: To slow down global warming, we'll either have to put the brakes on economic growth or transform the way the world's economies work. (2012-05-02)

Water treatments alone not enough to combat fluorosis in Ethiopia
Increased intake of dietary calcium may be key to addressing widespread dental health problems faced by millions of rural residents in Ethiopia's remote, poverty-stricken Main Rift Valley, according to a new Duke University-led study. (2012-04-27)

Climate change, biofuels mandate would cause corn price spikes
A study from Purdue and Stanford university researchers predicts that future climate scenarios may cause significantly greater volatility in corn prices, which would be intensified by the federal biofuels mandate. (2012-04-24)
