Annual Greenhouse Gas Index (AGGI) Indicates Sharp Rise in Carbon Dioxide and Methane in 2007
April 23, 2008
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.

ARCPAC Studies Link Between Arctic Pollution and Climate
April 9, 2008
NOAA scientists fly 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.

Sacramento: The Nation's Next Urban Flood Disaster?
March 2008
West Coast winter storms may lack the "star power" of East Coast hurricanes.
They aren't named at birth or routinely tracked by the media. But the impact
of these western cyclones, spawned over Earth's largest ocean and nourished
by long ribbons of moisture from the tropics, can be even more devastating
than their famous cousins back East.
Widespread power outages, flooding, and debris flows can follow,
rivaling the destruction of major hurricanes.

NOAA Invests $3 Million for Unmanned Aircraft System Testing
Pilotless Craft Gather Data for Hurricane Forecasts, Climate, West Coast Flood Warnings
January 22, 2008
Unmanned aircraft bearing automated sensors may soon help NOAA scientists
better predict a hurricane's intensity and track, how fast Arctic summer
ice will melt, and whether soggy Pacific storms will flood West Coast cities.
"This technology has the potential to revolutionize our monitoring of the
entire Earth," said Marty Ralph, a research meteorologist at
ESRL.

HMT Ready for Once-in-a-Decade Storm
January 2008
The NOAA Hydrometeorological Testbed is a national strategy that works
regionally to enhance weather forecasts and accelerate weather research
into operations. HMT combines state-of-the-art
observing systems and numerical modeling to develop tools for forecasters
who make decisions about watches and warnings for high-precipitation events, like the one beginning Jan. 3 that is expected to last four days. Such events
can cause flooding, bollix up transportation of all types and cause landslides
and other threats to people and property.
