James Hansen, the NASA scientist credited with raising the earliest and most consistent alarm over the dangers of human-caused global warming and climate change has announced that he’s leaving his government job so that he can put his full energies into the climate movement he helped spur.
After almost half a century working for the government, he told the New York Times on Tuesday he now considered it appropriate to step outside so he could more fully join the political and legal fight to limit greenhouse gases and runaway climate change.
“As a government employee, you can’t testify against the government,” he told the Times in an interview.
