New study: U.S. power plant emissions down

New study: U.S. power plant emissions down

Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in the journal Earth’s Future, a journal of the American Geophysical Union. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.

CIRES, NOAA observe significant methane leaks in a Utah natural gas field

CIRES, NOAA observe significant methane leaks in a Utah natural gas field

On a perfect winter day in Utah’s Uintah County in 2012, CIRES scientists and NOAA colleagues tested out a new way to measure methane emissions from a natural gas production field. Their results, accepted for publication in Geophysical Research Letters, constitute a proof-of-concept that could help both researchers and regulators better determine how much of the greenhouse gas and other air pollutants leak from oil and gas fields.

Greenhouse gases continue climbing; 2012 a record year

Greenhouse gases continue climbing; 2012 a record year

NOAA’s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many heat-trapping gases like carbon dioxide and methane, shows 2012 continued the steady upward trend that began with the Industrial Revolution of the 1880s.  Last year, CO2 at the peak of its cycle reached 400 ppm for one month at all eight Arctic sites for the first time.

NOAA real-time beach and water quality data now available for Lake St. Clair

NOAA real-time beach and water quality data now available for Lake St. Clair

Independence Day is right around the corner, and Michigan's Lake St. Clair residents and tourists are gearing up for a holiday weekend filled with fishing, swimming and boating activities. Beach managers can now view NOAA water quality predictions in real-time, instead of waiting 24 hours as before, to make timely decisions to safeguard public health and avoid unnecessary beach closures.

Carbon Dioxide at NOAA’s Mauna Loa Observatory reaches new milestone: Tops 400 ppm

Carbon Dioxide at NOAA’s Mauna Loa Observatory reaches new milestone: Tops 400 ppm

On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958.

The origins of cirrus: Earth’s highest clouds have dusty core

The origins of cirrus: Earth’s highest clouds have dusty core

Scientists have found that wispy cirrus clouds have cores of dust and metallic particles, answering questions about how these clouds form and giving insight into their climatic implications in the future.

Arctic nearly free of summer sea ice during first half of 21st century

Arctic nearly free of summer sea ice during first half of 21st century

For scientists studying summer sea ice in the Arctic, it’s not a question of “if” there will be nearly ice-free summers, but “when.” A new study says it could be before 2050.

Thin, low Arctic clouds played an important role in the massive 2012 Greenland ice melt

Thin, low Arctic clouds played an important role in the massive 2012 Greenland ice melt

Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.

New NOAA study estimates future loss of labor capacity as climate warms

New NOAA study estimates future loss of labor capacity as climate warms

A new NOAA study projects that heat-stress related labor capacity losses will double globally by 2050 with a warming climate. The impact will be felt the most by those who work outside or in hot environments.

NOAA research finds new way to identify which El Niño events will have biggest impact on U.S. winter weather

NOAA research finds new way to identify which El Niño events will have biggest impact on U.S. winter weather

New research from NOAA and the University of Washington suggests that using satellites to detect heat from deep convective cloud tops may be a way to detect El Niño and could help forecasters predict the unusual weather it causes.
