Hansen's Retirement From NASA Spurs Look at His Legacy

摘要

For decades, American climate scientist James Hansen published important papers on global warming and shared his data at influential congressional hearings-along with his policy prescriptions. He tussled with White House officials over his right to speak his mind, lobbied leaders the world over, and testified in defense of jailed activists. The 72-year-old has also been arrested five times in protests against the continued burning of fossil fuels or to demand that the United States put a price on carbon emissions.
