Recent summer heat waves unprecedented, study says

The summer heat waves over the past decade that killed thousands of people in Europe, scorched the Russian wheat crop, and sent Greenland's glaciers galloping to the sea are without parallel since at least 1400, according to a new study. The findings are based on a statistical analysis of summer seasonal temperatures inferred from tree rings, ice cores, lake sediments, and instrumental records.

New study links current events to climate change

Health roundup: Fans don't help in heat waves


For folks without air conditioning, an electric fan may seem like a life-saver in a steaming summer like this one. But researchers who looked at existing studies say it's possible fans do more harm than good when the temperature soars above 95 degrees. That's because blowing hot air over your body might actually increase heat stress and your risk of heat-related illness -- even if you feel like the fan is cooling you down. Better ideas: get out of your hot house and into a cool mall or library for a few hours; take cool showers.
