Direct Greenhouse Gas Emissions
Between the period 1970 to 2004, GHG emissions (measured in CO2-equivalent) increased at an average rate of 1.6% per year, with CO2 emissions from the use of fossil fuels growing at a rate of 1.9% per year. Total anthropogenic emissions at the end of 2009 were estimated at 49.5 gigatonnes CO2-equivalent. These emissions include CO2 from fossil fuel use and from land use, as well as emissions of methane, nitrous oxide and other GHGs covered by the Kyoto Protocol.
At present, the two primary sources of CO2 emissions are from burning coal used for electricity generation and petroleum used for motor transport.

“There is not enough exercise in this way of life. I try to make up by active gymnastics before I dress when I get up, by walking rapidly in the lower hall and the greenhouse after each meal for perhaps five to ten minutes, and a good hand rubbing before going to bed. I eat moderately; drink one cup of coffee at breakfast and one cup of tea at lunch and no other stimulant. My health is now, and usually, excellent.”
—Rutherford Birchard Hayes (1822–1893)
“A new father quickly learns that his child invariably comes to the bathroom at precisely the times when he’s in there, as if he needed company. The only way for this father to be certain of bathroom privacy is to shave at the gas station.”
—Bill Cosby (20th century)
