Publisher's Summary: Not long ago, scientists discovered that the Earth's climate is capable of changing abruptly, as if a switch were flipped, instead of slowly over hundreds or thousands of years. In the past, this type of abrupt change may have caused droughts, floods, and even regional cooling. For example, one archeologist says a long deep drought 4,200 years ago caused the collapse of the Old Kingdom of Egypt.Could global warming, which is gradually heating the planet, could bring Earth to another such "tipping point"? To find the answer, geologists are poring over evidence of past climate shifts by drilling for ice cores in Greenland's ice cap for evidence of past climate shifts and climate modelers are using computers to discover whether today's breadbaskets could become tomorrow's deserts.
