From glaciers on opposite sides of the world, some in the Andes, others in the Himalayas, he has built a strong case that the tropics were far colder 20,000 years ago, at the height of the last ice age, than most scientists thought possible...

Kilimanjaro, he reported, sports 80% less ice cover today than it did in 1912; a third of that loss has happened within the past decade.
