The Fervent Debate Over the Best Way to Confront Global Warming
In the late 1950s, Ian Burton, then a geographer at the University of Chicago, learned about a troubling conundrum with levees. These expensive and engineering-intensive strategies — which the U.S. Army Corps of Engineers favored for reining in floods along big river floodplains — worked well for holding back intermediate amounts of water. But they gave people a false sense of safety. After a levee went up, sometimes more people actually built and moved onto the land behind it. Then, if an oversized flood eventually poured over or broke through the levee, the disaster could damage more property and cause more havoc than it might have before engineers began meddling.

What began as a theory in the 1890s — that industrial emissions of carbon dioxide could increase global temperatures — had progressed to a scientific fact a century later. Scientists across a range of disciplines are studying the impact of the still-growing concentration of carbon dioxide and other so-called “greenhouse gases” in the atmosphere as they call for industrial and governmental policies to slow, then halt, the warming of the planet.
