More than 50 countries will send expeditions to (and focus their satellites on) Earth´s remotest regions during the fourth International Polar Year, which begins in March. By coordinating observations and analysis, scientists will gather extensive data that could lead to a new understanding of melting ice caps, the depleted ozone layer and thinning permafrost. They will also conduct some of the most detailed surveys of marine ecosystems and polar wildlife ever undertaken.

Although the extra month of Daylight Saving Time, a shift mandated by the Energy Policy Act of 2005, should save the energy equivalent of 100,000 barrels of oil a day, it may also trigger glitches in consumer gadgets and computer networks.
