Mark Hertsgaard

Mark Hertsgaard has investigated global warming for outlets including the New Yorker, NPR, Time, Vanity Fair, and the Nation. But the full truth did not hit home until he became a father and, soon thereafter, learned that climate change had already arrived―a century earlier than forecast―with impacts bound to worsen for decades to come. He is author of Generation HOT: Living Through the Next Fifty Years on Earth.
