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

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

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. ...

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: ...

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.
