Did humans almost become extinct?

The AP with Fox News hosting reports:

Human beings may have had a brush with extinction about 70,000 years ago, an extensive genetic study suggests.

The human population at that time had been gradually reduced to small isolated groups across eastern and southern Africa, apparently because of massive droughts lasting tens of thousands of years, according to an analysis released Thursday.

The report notes that a separate study by researchers at Stanford University estimated the number of early humans may have shrunk as low as 2,000 before numbers began to rapidly expand again in the period known as the Late Stone Age. …

Questions:

Have Al Gore and Barbra Streisand confirmed such a thing almost happened?

Do they know whether greenhouse gas emissions were involved?

What do the Dixie Chicks say?

Back when the human population “may have shrunk as low as 2,000,” were there candidates like Barack Obama who offered “change we can believe in?”

If there was a crude phone precursor, did someone like Hillary answer it at 3 AM?

And could they solve problems like seating the Florida and Michigan delegations at what passed for the Democrats' convention tens of thousands of years ago?
