U.S. CO2 emissions have been steadily falling for over a decade. [1]

Twice that long on a per-capita basis.

Considering that broad consensus about global warming was only formed in 1980s, that's not a terrible track record.

A far bigger problem than stupidity or procrastination is the industrialization of 3 billion people. There's no great solution to that.
