Night-warming effect over large wind farmsLast Updated on 2012-05-01 00:00:00
Study indicates that land surface temperatures have warmed in the vicinity of large wind farms in west-central Texas, especially at night,
Scientists Find Night-Warming Effect
Over Large Wind Farms in Texas
Wind turbines interact with atmospheric boundary layer near the surface
Large wind farms in certain areas in the United States appear to affect local land surface temperatures, according to a paper published today in the journal Nature Climate Change. The study, led by Liming Zhou, an atmospheric scientist at the State University of New York- (SUNY) Albany, provides insights about the possible effects of wind farms. The results could be important for developing efficient adaptation and management strategies to ensure long-term sustainability of wind power.

Wintertime droughts are increasingly common in the Mediterranean region, and human-caused climate change is partly responsible, according to a new analysis by NOAA scientists and colleagues at the Cooperative Institute for Research in Environmental Sciences (CIRES). In the last 20 years, 10 of the driest 12 winters have taken place in the lands surrounding the Mediterranean Sea.
“The magnitude and frequency of the drying that has occurred is too great to be explained by natural variability alone,” said Martin Hoerling, Ph.D. of NOAA’s Earth System Research Laboratory in Boulder, Colo., lead author of a paper published online in the Journal of Climate ... More »
Targeting other climate change gasesLast Updated on 2011-08-04 00:00:00NOAA study: Slowing climate change by
targeting gases other than carbon dioxide
The direct warming influence of all long-lived greenhouse gases in the atmosphere today attributable to human activities. CO2’s warming influence of 1.7 watts/m2 is equivalent to the heat from nearly 9 trillion 100-watt incandescent light bulbs placed across Earth’s surface. The combined influence of the non-CO2 greenhouse gases is equivalent to the heat from about 5 trillion bulbs. The category “other”includes a few very long-lived chemicals that can exert a climate influence for millennia.

Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions... More »
IPCC Working Group ILast Updated on 2011-06-29 00:00:00
IPCC Working Group I assesses the scientific aspects of the climate system and climate change for the Intergovernmental Panel on Climate Change (IPCC). It is responsible for producing reports as part of IPCC's multi-volume Assessments. IPCC Assessments with Working Group I reports were released in 1990, 1995, 2001, and 2007. The next Working Group I report (for Assessment Report 5 or "AR5") is scheduled to be finalized in September 2013. IPCC Working Group I is composed of an international group of scientists. Writing team membership for the Working Group II contribution to the AR5 consists of 259 Coordinating Lead Authors, Lead Authors, and Review Editors.
The reports of IPCC Working Groups have been among the most influential scientific reports on climate change
The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 by the... More »
Black Carbon and Climate ChangeLast Updated on 2011-04-21 00:00:00
This data visualization (image) uses data from NASA’s GEOS-5 Goddard Chemistry Aerosol and Transport (GOCART) climate model to show atmospheric concentrations of black carbon on 26 September 2009. More than three-quarters of the world’s black carbon is thought to come from developing countries, discharged from cookstoves, open burning, and older diesel engines. Aerosol optical thickness ranges nonlinearly from 0.002 (transparent) to 0.02 (purple) to 0.2 (white). Animations of global black soot transport are available at http://tinyurl.com/64nbykb and http://tinyurl.com/69w9s6z.
