[ Watch the Video ] NOAA´s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s. Started in 2004, the AGGI reached 1.29 in 2010. That means the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased by 29 percent since 1990, the...

Cigarette smoking, forest fires and woodburning can release a chemical that may be at least partly responsible for human health problems related to smoke exposure, according to a new study by NOAA researchers and their colleagues. Using a custom mass spectrometer designed by the researchers, the NOAA-led team was able get the first look at levels of the chemical, isocyanic acid, in the atmosphere. Isocyanic acid has been difficult to detect with conventional measurement techniques. "We found...

The deadly heat wave that crippled Russia last summer was due to a natural atmospheric phenomenon often associated with weather extremes and not directly caused by global warming, according to a new study by the National Oceanic and Atmospheric Association (NOAA). And while the scientists could not attribute the intensity of the Russian heat wave to climate change, they did find that extreme heat waves are likely to become more frequent in the region in the coming decades. The researchers...

NOAA scientists are now flying through springtime Arctic pollution to find out why the region is warming "” and summertime sea ice is melting "” faster than predicted. Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23."The Arctic is changing before our eyes," said A.R. Ravishankara, director of the chemistry division at NOAA's Earth System Research Laboratory in Boulder, Colo. "Capturing in...
