Iowa native James Hansen wishes he wasn't right about global warming

NASA’s top climate scientist in 1988, Hansen warned the world on a record hot June day 30 years ago that global warming was here and worsening. In a scientific study that came out a couple of months later, he even forecast how warm it would get.

The hotter world that Hansen envisioned in 1988 has pretty much come true. Three decades later, most climate scientists interviewed rave about the accuracy of Hansen’s predictions given the technology of the time.

Hansen, a native of Denison, Iowa, and a former World-Herald newspaper carrier, won’t say, “I told you so.”
