NOAA Earth System Research Laboratory http://www.esrl.noaa.gov/ News from the NOAA Earth System Research Laboratory Thu, 24 Apr 2008 20:23:15 GMT Annual Greenhouse Gas Index (AGGI) Indicates Sharp Rise in Carbon Dioxide and Methane in 2007 http://www.esrl.noaa.gov/media/2008/aggi.html In 2007 global levels of atmospheric carbon dioxide, the primary driver of global climate change, increased by 0.6 percent, or 19 billion tons. Additionally methane rose by 27 million tons after nearly a decade with little or no increase. NOAA scientists released these and other findings today as part of the Annual Greenhouse Gas Index (AGGI), which tracks data from 60 sites around the world.

NOAA scientists and staff will host a reception for the young scientists/artists on Wednesday, April 23.

Rebecca Morss of the National Center for Atmospheric Research. Weather forecasts are inherently uncertain, and meteorologists have substantial information about weather forecast uncertainty that is not readily available to most forecast users. This uncertainty information has potential to benefit users by helping them make more informed forecast-related decisions. Yet effectively communicating uncertainty to non-meteorologists remains challenging.

Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23.
