Hastily constructed presentation on carbon emissions T.J. Blasing - PowerPoint PPT Presentation

Hastily constructed presentation on carbon emissions T.J. Blasing For NOAA ESRL meeting, May 15 2008 Brought to you by:

Marland & friends National Carbon Assessments Fossil Carbon Embodied Carbon Standing Woody Biomass

Have already done Annual C emissions for each state Monthly C emissions for USA total Jay Gregg and Bob Andres will Expand to Monthly C emissions for each state Monthly C emissions for other countries Collaboration with Vulcan Carbon tracker Sulfur tracker
