A stack of one trillion one-dollar bills would reach the Moon and back four times. Janet Yellen is proposing to spend a stack, not a fistful, of dollars that would reach to the Moon and back twelve times. That's the scale of spending she's talking about - it is, literally, astronomical. And she wants to spend this money on the nebulous idea of anthropogenic climate change.

U.S. Treasury Secretary Janet Yellen said on Saturday that the global transition to a low-carbon economy requires $3 trillion in new capital each year through 2050, far above current annual financing, but that filling the gap is the biggest economic opportunity of the 21st century.
