How the U.S. compares 23.6% Top 8 countries make 44% of CO2

CO2 concentrations at the Mauna Loa Observatory in Hawaii (as of May 2009) http://www.esrl.noaa.gov/gmd/ccgg/trends/co2_data_mlo.html

What about before 1960?

How do we remove this CO2? Carbon sink: is a reservoir of carbon that accumulates and stores carbon for an indefinite period. The main sinks are: Absorption of carbon dioxide by the oceans Photosynthesis by plants and algae to turn the carbon into plant matter Injection of CO2 emissions deep into geological subsurface

Breakdown

What is a carbon footprint? Carbon footprint (FP): is “the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product” (UK Carbon Trust 2008). Everyone in this room has a FP

Let’s determine your C-FP
