...fact, though, that everyone agrees on: the amount of carbon dioxide in the atmosphere is increasing steadily. It is near 360 parts per million today, vs. 315 p.p.m. in 1958 (when modern measurements started) and 270 p.p.m. in preindustrial times (as measured by air bubbles trapped in the Greenland ice sheet...
...with global warming, melting ice from Greenland and the Arctic Ocean could pump fresh water into the North Atlantic; so could the increased rainfall predicted for northern latitudes in a warmer world. Result: the Gulf Stream's water wouldn't get saltier after all and wouldn't sink so easily. Without adequate resupply, the southerly underwater current would stop, and the Gulf Stream would in turn be shut...
...mechanism in the earth's internal motions under the ocean floor. Suddenly, Wegener's disreputable ideas became reputable. Renamed plate tectonics, they gave geology a single unifying theory, explaining everything from earthquakes and volcanoes to the formation of mountain ranges and ocean basins. Sadly, Wegener, who perished on the Greenland icecap in 1930 at age 50, didn't live...
...these cycles occur. According to Bill Gray, a hurricane expert from Colorado State University, one reason may be a phenomenon known as the "Atlantic conveyor." The subject of much recent research, the conveyor is a gigantic oceanic flywheel that transports cold water from the seas off Iceland and Greenland in a majestic, slow current along the bottom of the ocean to Antarctica, where it surfaces several decades later and flows back north, absorbing heat as it passes the equator. The conveyor seems to have kicked into a faster gear lately, bringing warm equatorial water north before it can cool. Hurricanes...
...Travel Channel occasionally makes you want to book a flight, it usually cures your wanderlust safely. Lonely Planet, when hosted by energetic Brit Ian Wright, gives you the parts of the world you'd never see even if you decided to use your vacation time to go to Greenland and Ethiopia. Wright will eat anything, climb anything and bother anyone in the cheeriest way possible. Almost as good is Adventure Bound, where insane Australian former bricklayer Alby Mangels delights in endangering his life in creative ways, like filming the marijuana plantations of Caribbean drug lords. It's as though Kramer...
