Watch the global carbon cycle! The link below takes you to a NASA page that loads a 90 megabyte animated GIF file showing chlorophyll concentration (in the oceans) and Normalized Difference Vegetation Index (NDVI, on land) as the seasons change.

Two Catchment Management Authorities in Australia begin soil carbon programs
Posted by Peter Donovan 14 years, 7 months ago

Both programs are aimed at enhancing soil health and the sustainability of farming, rather than at "offsets" to fossil fuel emissions.
