...Shoemaker and his colleagues see it, a giant comet broke apart as it whipped around the sun. Over time, chunks of the comet separated but remained strung out in the same orbit. Then 65 million years ago, as the earth passed through the comet's orbit, it collided with the largest chunk, causing the Great Extinction. Perhaps only a year or two later, as the earth again entered the trail of cometary debris, it met a second, smaller chunk. Where did the second impact occur? This time no search is necessary. Shoemaker points to a well-known crater...
...upper atmosphere is subject to countless fluctuations, mathematicians say the theoretical limit for a reasonably accurate forecast is less than two weeks. But within this time frame, a number of innovations have enhanced the meteorologist's prophetic powers. Supercomputers build mathematical models that show the interaction of wind, sun, temperature and humidity across the entire globe. And Doppler radar -- the technology at the heart of the Norman station -- is adept at spotting the destructive midsize squalls that have traditionally taken forecasters by surprise. By bouncing microwaves off the tiny droplets in the center of a cloud and picking...

Couched at the top of one of countless waterfalls that bathe the southeastern foothills of the Peruvian Andes, I enjoy the cool breath of the cascade, which takes the edge off the equatorial sun. From nearby promontories, an observer can look upward to the cloud forests that cling to the mountainous rim of the Amazon basin, or down into the steamy lowland rain forests that extend thousands of miles to the east. As far as the eye can see and beyond, there are no villages, roads or towns. Lying below is the Manu, a 7,000-sq.-mi. area...
