Global Climate Change


Mercury in Coastal Fog Linked to Deep Ocean Water

According to researchers, coastal fog in California contains elevated mercury levels, which may be the result of upwelling deep ocean water along the coasts. Upwelling processes bring mercury to the surface of the water, where it enters the atmosphere and is absorbed by fog.

Soot from Arctic Wildfires Hover Over Greenland

Recent observations from satellites have shown that the smoke from Arctic wildfires is drifting over the Greenland ice sheet, settling on the ice as soot and making it more likely to melt under the sun.

High Nitrous Oxide Levels in California

With a new method for estimating greenhouse gases, researchers have found that the levels of nitrous oxide, a potent greenhouse gas, are much higher than previous predictions.

Artificial Watershed Gets First Rain

The world’s only artificial watershed inside the Biosphere 2 at the University of Arizona receives its first rain, giving researchers the first opportunity to study how water, soil, plants, and microbes interact in a realistic setting; this rare chance could help improve future global climate models.

A Tobacco Tree Could be Used as Biofuel

Researchers at Royal Holloway have identified a tobacco tree that could produce biofuels, and have been awarded a grant for further research from the European Union.

Arizona State University Received Grant to Advance Carbon Capture Technology

In order to pursue high-risk, high-reward advances with the potential to change the way the nation consumes and generates energy, the U.S. Department of Energy (DOE) has awarded Arizona State University (ASU) a grant for alternative energy research.

Sea Levels Rising Faster than Previously Expected

According to new research, sea-levels are rising 60 perfect faster than central projections made by the Intergovernmental Panel on Climate Change (IPCC).

Drought Stress Makes Forest Ecosystems Vulnerable

Researchers have found that increasing drought conditions have made plants operate at their top safety threshold, making forest ecosystems vulnerable to escalating environmental stress.



Lidar Confirms Coastal Impacts of Hurricane Sandy

In a new U.S. Geological Survey analysis of recently collected lidar coastal data, the devastation and future coastal vulnerability of the region after Hurricane Sandy wreaked havoc is clear. The research documented particularly dramatic impacts within the Fire Island National Seashore on Long Island, NY.

Drained Wetlands Produce Greenhouse Gases

According to new research from universities in Sweden, drained wetlands are capable of producing as much greenhouse gas emissions as Swedish industry.

APWA Collaborates on Consortium’s New White Paper

The American Public Works Association (APWA) will be teaming up with 20 national organizations in the new version of Homeland Security Consortium’s (NHSC) white paper, “Protecting Americans in the 21st Century: Priorities for 2012 and Beyond.”

Warming Temperatures Increase Stress on Public Lands

Researchers have discovered that climate change is creating additional stress on western rangelands, and as a result land owners should consider a reduction or elimination of livestock and other large animals from public lands.

Mine Waste Has Great CO2 Storage Potential

A mining engineer and geologist says it’s time to economically value the greenhouse gas-trapping potential of mine waste and start making money from it.

Future Warming on Higher End of Climate Projections

Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by scientists at the National Center for Atmospheric Research (NCAR).

Plants and Soils Could Intensify Climate Change

Scientists from the American Meteorological Society (AMS) and the University of California, Berkley have demonstrated that plants and soils could release large amounts of carbon dioxide as global climate warms.

Carbon Dioxide Could Prevent a Future Ice Age

According to research from the University of Gothenburg, Sweden, emissions of fossil carbon and the resulting increase in temperature could prevent the earth from having a future ice age.

Warmer Temperatures Cause Aquatic Animals to Shrink

According to a new study, warmer temperatures cause greater reduction in the sizes of adult aquatic animals than in land-dwelling species.

Carbon in Soil Plays a Role in Global Change

A research team has discovered that a source of carbon emissions could help scientists understand past and future global change.

Global Warming Hinders Species' Recovery After Mass Extinction

Researchers have discovered that global warming is the reason plants and animals had a hard time recovering from the largest mass extinction in Earth’s history 250 million years ago.

Mountain Meadows Dwindling in the Pacific Northwest

Some high mountain meadows in the Pacific Northwest are declining rapidly due to climate change as reduced snowpacks, longer growing seasons, and other factors allow trees to invade ecosystems that once were carpeted with grasses, shrubs and wildflowers.
