Numbers

Age of universe, approx 15 Billion years (15,000,000,000).
Age of planet earth, approx 4.5 Billion years (4,500,000,000).
Age of Homo sapiens, approx 500 thousand years (500,000).
Reliance on fossil fuels started approx 3 hundred years ago.
Known oil reserves approx 40 years. Cost of exploration rising.
World energy consumption surged 4.3 per cent last year, the biggest percentage rise since 1984 and the largest volume increase ever.
World energy consumption is expected to increase 40% to 50% by the year 2010, and the global mix of fuels - renewables (18%), nuclear (4%), and fossil (78%) - -is projected to remain substantially the same as today; thus global carbon dioxide emissions would also increase 50% to 60%.
CO2 inflection point, the point past which damage to the environment is irreversible and permanent, expected within the next 50 years.
