Carbon Dioxide Emissions on the Rise

Emissions of CO2, a greenhouse gas, have risen steadily for the last 30 years.

The burning of fossil fuels releases carbon dioxide into the atmosphere. CO2 is a greenhouse gas, and is primarily responsible for human-induced climate change. The trend: upward—sharply—especially among emerging nations such as China, India, and Brazil.

Colors represent total CO2 emissions by year between 1960 and 2007.

Ecoclimax is defined by Odum (1969) as the culmination state after a succession in a stabilized ecosystem in which maximum biomass (or high information content) and symbiotic function among organisms is kept per unit of available energy flow.
