NASA Satellite Measures Earth's Carbon Metabolism

Roland Piquepaille writes "To celebrate Earth Day, the NASA Earth Observatory recently revealed global measurements of the Earth's metabolism. 'Combining space-based measurements of a range of plant properties collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) with a suite of other satellite and surface-based measurements, NASA scientists produce composite maps of our world's 'net primary production' every 8 days. This new measurement is called net production because it indicates how much carbon dioxide is taken in by vegetation during photosynthesis minus how much is given off during respiration.' Check this column for a summary including the usefulness of such measurements. You'll also find maps showing the seasonal variation of Earth's net primary production."

Now show where carbon get produced!

Show where it gets produced contrasted with where it gets consumed and show the rate of the difference. Combine that with charts showing how typical day to day activities contribute to either column. Now you'll have something that can help the average person make a difference! This is a good start!

Nah, most people will probably just leave it for someone else to take care of, like their children. I mean, making a difference takes effort, and Joe Public is too lazy to put in effort that doesn't directly benefit himself.
