Jeffrey Sachs is an economist who burst upon the international scene when he became advisory to Gorbachev on the transition from communism to...something else. He then had the same role with Poland and a couple other countries. Then, be became arrested by the spectacle of poverty in Africa and, as is his wont, decided to come up with the whole solution and "them them to do it." Somewhere along the line, came climate change/global warming, which he added to his plans for the world. By all accounts, he is a very dedicated, incredibly energetic, and, it is said, brilliant and charismatic man. As to what the great scheme for Africa amounted to, there is the book by Munk and my briefest of comments...

Sounds like the old, “If I was absolute dictator of the world, everything would be great” mantra of the left.

Poverty has been decreasing, not because of a anti-poverty plan but because technology makes it easier for people to get knowledge and tools and easier for buyers and sellers to reach one another.

I think the problem of global warming will solved in a similar fashion. If we set up ways to pay for the costs of greenhouse gas emissions and deforestation, smart people will invent ways to power the world without harming the environment.
