...Pegasus missile from under their right wing and send it roaring up into the sky. At 31 km, more than double civil aviation altitude, a black, windowless, pilotless sliver of finned metal shaped like a flattened dart will separate from the Pegasus' nose and scream down into the ocean. NASA estimates the X-43 will reach a cruising speed of Mach 7, seven times the speed of sound, or 2 km per second, in the few moments before it hits water. By August 2002, nasa wants to be at Mach 10. Then it'll start thinking about runways and cutting...
Reunion island, a cone of volcanic rock that rises out of the Indian Ocean some 750 km east of Madagascar, is over 9,500 km away from Paris but - in theory, at least - is just as French as the Champs Elysées or the Côte d'Azur. Since 1946 the island has been a French département, like the country's 99 other local administrative units. Yet you don't have to spend long in the shadow of Réunion's active volcano to realize that the island is a long way from Lyons. Despite...
...English merchant Robert Thorne first proposed the idea in 1527: sail from Western Europe across the top of the continent to the Far East. This northern passage would be far quicker than the one then used, around the southern tip of Africa. But few sailors dared risk the Arctic Ocean's freezing temperatures, ice-clogged seas and blinding fog. Now, though, Thorne's idea is being taken more seriously, owing to global warming. The sea ice along the northern coast of Siberia is retreating, and last year a team of international scientists reported that ice-free routes have emerged during...
...Climate Change makes plain, the trend toward a warmer world has unquestionably begun. Worldwide temperatures have climbed more than 1[degree]F over the past century, and the 1990s were the hottest decade on record. After analyzing data going back at least two decades on everything from air and ocean temperatures to the spread and retreat of wildlife, the IPCC asserts that this slow but steady warming has had an impact on no fewer than 420 physical processes and animal and plant species on all continents...
...contrast, if melting ice caps dilute the salt content of the sea, major ocean currents like the Gulf Stream could slow or even stop, and so would their warming effects on northern regions. More snowfall reflecting more sunlight back into space could actually cause a net cooling. Global warming could, paradoxically, throw the planet into another...
