New Study Projects World Population of 11B by 2100
vinces99 (2792707) writes Using modern statistical tools, a new study led by the University of Washington and the United Nations finds that world population is likely to keep growing throughout the 21st century. The number of people on Earth is likely to reach 11 billion by 2100, the study concludes, about 2 billion higher than widely cited previous estimates. The paper published online Sept. 18 in the journal Science includes the most up-to-date numbers for future world population, and describes a new method for creating such estimates. "The consensus over the past 20 years or so was that world population, which is currently around 7 billion, would go up to 9 billion and level off or probably decline," said corresponding author Adrian Raftery, a UW professor of statistics and of sociology. ... The paper explains the most recent United Nations population data released in July. This is the first U.N. population report to use modern statistics, known as Bayesian statistics, that combines all available information to generate better predictions.
Most of the anticipated growth is in Africa, where population is projected to quadruple from around 1 billion today to 4 billion by the end of the century. The main reason is that birth rates in sub-Saharan Africa have not been going down as fast as had been expected. There is an 80 percent chance that the population in Africa at the end of the century will be between 3.5 billion and 5.1 billion people.

You forgot to check 'Post Anonymously'. Don't you just hate it when that happens?
Chuuch. Preach. Tabernacle.
The irony is that you can only really accomplish the needed sustainability if you do NOT try to accomplish the former.
Communism and to a lesser extent Socialism always attack the rich and promise the spoils to "the people". In the end the people always end up with nearly nothing (see Venezuela).
Whereas that evil vile capitalism has only ever just pulled millions upon millions of people out of poverty, worldwide, over the past 60 years.
Go facepalm yourself.
Faster! Faster! Faster would be better!
The CO2 being produced through breathing is a net neutral.
Plants are carbon neutral. They have been since the carboniferous era.
CO2 from using power will be the issue, unless we start a aggressive plan to stop using CO2 emitting technology for power.
By aggressive, I mean 75 years.
