Fossil fuels drove most of the growth & were almost 80% of supply in 2000.
Atmospheric CO2 measured at Mauna Loa, Hawaii.
Source: NOAA Climate Monitoring and Diagnostic Laboratory
Direct measurements of CO2 show continued rise
Concentration reached 380 ppmv in 2005
Fossil-fuel origin of most of the increase is confirmed by reduction in C-14 concentration.
The last 400 and next 100 years of global temperature
Mid-range scenarios are heading for T‘s last seen 30 million years ago.
