Reduction in Carbon Dioxide Emissions Definitely Needed to Address Global Warming

When fossil fuels are burned, other climate-forcing gases are produced in addition to long-lasting carbon dioxide. Diesel combustion in vehicles or coal in power plants creates soot particles, which also contribute to global warming, albeit only briefly as they disappear quickly from the atmosphere.

Arctic Ocean Traps Far-Infrared Radiation That Could be Contributing to Polar Climate Warming

Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice.

Extreme Events in the Future Pose Hazards to NASA’s Mission, Infrastructure and Workforce

A new study in the latest issue of the Bulletin of the American Meteorological Society provides an in-depth look at how NASA facilities have been affected by climate extremes and climate change in recent years and how the agency is preparing for the future.

Researchers Accurately Measure Concentrations of PCB Pollutants in Ice of Alpine Glacier

As glaciers increasingly melt in the wake of climate change, it is not only the landscape that is affected. Thawing glaciers also release many industrial pollutants stored in the ice into the environment.

Deep Ice Sheet Coring Drill Provides Cores for Climate Study

Wisconsin is famous for its ice fishers — the stalwarts who drill holes through lake ice in the hope of catching a winter dinner. Less well known are the state's big-league ice drillers — specialists who design huge drills and use them to drill deep into ice in Greenland and Antarctica, places where even summer seems like winter.

Antarctic Ozone Hole Reaches Annual Peak Size in September

The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America.

New Technique to Accurately Measure Major Greenhouse Gases

By remotely "combing" the atmosphere with a custom laser-based instrument, researchers from the National Institute of Standards and Technology (NIST), in collaboration with researchers from the National Oceanic and Atmospheric Administration (NOAA), have developed a new technique that can accurately measure—over a sizeable distance—amounts of several of the major "greenhouse" gases implicated in climate change.

Weight of Penguin Chicks Connected to Weather Conditions

Adélie penguins are an indigenous species of the West Antarctic Peninsula (WAP), one of the most rapidly warming areas on Earth. Since 1950, the average annual temperature in the Antarctic Peninsula has increased 2 degrees Celsius on average, and 6 degrees Celsius during winter.

Using a New Regenerative Thermal Oxidizer Chemical Plant Reduces Emissions, Carbon Footprint and Operating Expenses

Pure Terephthalic Acid (PTA) is a white powder-substance used extensively in the production of plastics and polyester products like fibers or films. The material is produced in a pressurized reactor where acetic acid and xylene are combined chemically in the presence of catalyst.

Stricter Fisheries Management Overcomes Detrimental Effects of Climate Change Disturbances

A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño, according to the Wildlife Conservation Society.
