Kyoto II? Fuggedaboutit.

Stop the climate negotiations. There's a better answer. Two words: white roofs.

If stats from a paper by Hashem Akbari of the Lawrence Berkley National Laboratory are correct, re-roofing 100 global cities could stop 44 metric gigatons from entering the atmosphere -- more than all the countries in the world combined emit now.

A white-out never looked so cool.

Morning Brief: Ike poised to strike U.S. Gulf Coast

Top Story

As Hurricane Ike menaces Texas, the U.S. National Weather Service is warning many Gulf Coast residents to evacuate lest they face "certain death." Oil companies are bracing for the worst. Crude oil for October delivery rose to slightly above $102 overnight, however -- hardly a sign of panic.

The storm, currently a Category 2 that may grow into a Category 3, is projected to slam into the coast near Galveston early Saturday morning and continue north through the state. "Greater Houston faces the real possibility of a direct hit," the Houston Chronicle warns, citing the storm's anticipated 100-mph winds. Further south, a 20-foot "storm surge" threatens to breach coastal walls that are only 17 feet high in most places. "Science Guy" Eric Berger is hoping for a near-miss.
