...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...
...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...

It's as though Kramer...

Last year, he became the first person to reach the top of a remote peak in Greenland, naming it "Minarjnik" after his wife, Mrinalini Mani, and his two sons, Arjun and Nikhil...
