"A new NASA-led study seven years in the making has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit, therefore reducing global warming. This finding resolves a long-standing debate about a key component of the overall carbon balance of the Amazon basin."

During photosynthesis, plants emit what is called fluorescence - a form of light invisible to the naked eye but detectable by satellites orbiting hundreds of miles above Earth. NASA scientists established a method to turn this satellite data into global maps of the subtle phenomenon in more detail than ever before.

CO2 map

A downloadable US forest map assembled from space-based radar, satellite sensors, computer models, and a massive amount of ground-based data. It is possibly the highest resolution and most detailed view of forest structure and carbon storage ever assembled for any country. "Trees are one of Earth's largest banks for storing the carbon that gets emitted by natural processes and human activities. Forests cover about 30 percent of the planet's surface, and as much as 45 percent of the carbon stored on land is tied up in forests."

"Have you ever wondered what the tree population and density of the United States looks like? This amazing map shows just that. Created by Josef Kellndorfer and Wayne Walker of Woods Hole Research Center in conjunction with the U. S. Geological Survey Science Center's Earth Resources Observation and Science (EROS) Center and the US Forest Service, the map was generated based on a series of data sources including readings collected from space-based radars, satellite sensors, computer models, and simply counting trees the old-fashioned way. The map was created for NASA to help determine how the world's forests have the potential to store more carbon in the future."

"[Noreen] Thomas [a farmer] enjoys this view from hundreds of miles above Earth's surface -- not just for the beauty, but the utility. She is among a growing group of Midwest farmers who rely on satellite imagery from Landsat to maximize their harvest and minimize damage to their fields. It's become another crucial tool like their tractors and sprinklers."

A new video series from the National Research Council summarizes what scientists have learned about global warming and climate change.

I think all of the CB people that attended the workshop will agree... you have got to check out CHANGE Viewer ASAP... The Climate Change and Human Health project is designed to provide educators with the resources to engage high school students in critical thinking about climate change and the potential impact on human health across the planet. Activities developed for this project all use an interactive geospatial globe called CHANGE Viewer, to view and access climate and human related datasets.

Amazing images of wildfires, hurricanes, status of the gulf oil spill, etc. Definitely worth checking out!

"The MODIS Rapid Response System generates daily near-real-time imagery of the oil in the Gulf of Mexico, including GIS compatible formats. Images are available in photo-like, true and false color from both the Terra and Aqua satellites at 2km, 1km, 500m, and 250m resolutions."

NASA's Global Climate Change website hosts an extensive collection of global warming resources, including videos, infographics, quizzes, and interactives.
