Researchers studying the effects of ancient climate patterns on Antarctic waters have reached an alarming conclusion: The inhabitants of those seas were able to cling to life by the thinnest of margins during past ice ages, but they might not be able to weather the temperature increases predicted for the next century. In particular danger are the birds and mammals occupying the top of the food chain, such as emperor penguins and sea lions.
