When I asked climate change expert Tony McMichael back in March how he thought the world would deal with climate change, he said, "It's likely to be an extraordinary century and we're going to have to have our wits about us to get through it."
But the legions of scientists he inspired will have to go on without him. McMichael died in September in his native Australia from complications of pneumonia, leaving behind the fledgling field he founded — determining the health effects of climate change.
