saying you don't believe in it is like saying you don't believe in gravity or the existence of other planets. it isn't something you believe in or not.....it is something you understand or don't understand.
natural sources of CO2 occur within the carbon cycle where billions of tons of atmospheric CO2 are removed from the atmosphere by oceans and growing plants, also known as ‘sinks,’ and are emitted back into the atmosphere annually through natural processes also known as ‘sources.’ when in balance, the total carbon dioxide emissions and removals from the entire carbon cycle are roughly equal.
since the 1700’s, human activities, such as the burning of oil, coal and gas, and deforestation, have increased CO2 concentrations in the atmosphere. in 2005, global atmospheric concentrations of CO2 were 35% higher than they were before the Industrial Revolution.
so just out of curiosity what are you basing your 5% figure on?
anyway.......great movie.
