Ok, I get what the article you linked to is saying, but I think it's really uninformative. Those graphs are the derivative of the population. What I would most like to see is the absolute number of people on earth over time and then into the future. The derivative, though important, is not as useful (to me) as the absolute number. Hans Rosling has some good TED talks on it, but I think they are probably out of date by now.

The graph for the actual population projection was basically linked in the article:
