...monsoon is not the only climate cycle that human activity could alter. Atmospheric scientist John M. Wallace of the University of Washington believes that rising concentrations of greenhouse gases are already beginning to have an impact on another important cycle, known as the North Atlantic or Arctic Oscillation. In this case it's not the warming these gases create in the lower atmosphere that is key, but the cooling they cause in the stratosphere, where molecules of carbon dioxide and the like emit heat to space rather than trapping it in the upper atmosphere. This stratospheric cooling, Wallace and others...
...roll like barrels on a wave. Water, power and transportation lines will be cut. The subway that runs under the bay could be a death trap. By the time the dust settles, more than 100,000 people will be homeless. Economic losses will total at least $35 billion. The human cost will be immeasurable...
...Human nature stays constant enough that it's easy to answer this one. Yes, someone will build a perpetual-motion machine in the next few years. Or, more likely, dozens of perpetual-motion machines, as starry-eyed inventors have been doing since medieval times. Not a single one will work, but they'll keep trying. Nothing is more seductive, after all, than the idea of a free lunch...
...this, the third installment of TIME's 100 questions for the 21st century, we focus on the great unsolved riddles of space and time and human consciousness. Our journey is necessarily brief--we don't have enough fuel to travel more than 25 years or so into the future. But our guides are patient and remarkably lucid. We come back excited by how much can be foretold--about cloning, evolution, earthquakes and space travel--and humbled by how much is yet unknown...
...whether we will travel to the stars, the answer is probably yes, but it will take a long time. Maybe 500 years. If you ask whether any human being will travel to the stars within the 21st century, the answer is certainly no. The difference between traveling to the nearest star and traveling around our own solar system is about the same as the difference between swimming across the Atlantic and swimming across the Potomac. To get across the Atlantic you need to have a boat or an aircraft. To get to the nearest star you need to have...
