After a 20 year absence from Capitol Hill, former Secretary of State George Shultz returned last Friday to urge members of Congress to act on climate change.

The day Hurricane Sandy slammed into the East Coast, I was in Mali, a country in West Africa’s Sahel region. As a native New Yorker, I was stunned and dismayed to see pictures of the flooded streets and tunnels of Manhattan, of destroyed homes and schools on Staten Island, and of thousands of my fellow New Yorkers displaced and in shelters. But I was even more struck by the indiscriminate nature of what I was witnessing both in Mali (one of the world’s poorest countries) and the United States (one of its richest): massive humanitarian emergencies resulting from more extreme weather.

In a darkly-lit house on a dusty, garbage-strewn street on the outskirts of Bamako, an elderly couple and a man in a white robe are seated on the floor. Amadou, the owner of the home, is approximately 70 years old and a retired gardener. He says that since rebels took over northern Mali last April, 16 members of his extended family have come to live with him, having been forced to flee their hometown of Timbuktu.
