...understand its pedigree. Depth is time, and the lower you go, the further back in history you travel. As ice formed in Greenland, year after cold year, bits of atmosphere were trapped in the layers. Drilling into the ice and fishing out samples--ice cores--that contain tiny bubbles of that ancient air can reveal the temperature, the concentration of greenhouse gases, even the ambient dust from the year that layer was formed. It's like tree rings but for climatic history. "In order to predict the future, we have to understand the past," says Minik Rosing, a geologist...

For concerned parents, limiting BPA exposure for children isn't that hard. Watch out for the number 7 on the bottom of plastic containers, which often means they contain BPA; avoid canned foods for children; and don't microwave plastic food containers that contain the chemical, as heat can make it easier for BPA to leach. Ultimately, though, it may not even matter what the FDA does - a new report by the Investor Environmental...
