...levels - after all, greenhouses pump in extra CO2 to encourage growth - but they fail to note that hotter summers and increasing droughts could threaten agriculture. They assert that sea levels can rise only 1.5 ft. over the coming century, ignoring the very real risk of accelerated melting of the Greenland and Antarctic ice sheets, which would multiply that number. They downplay the risks of carbon dioxide as a greenhouse gas. And they make a habit of referring to any climate scientist who expresses fear over a warmer future as a "doomsayer" - a bit of a loaded term...
Some of the best evidence linking rising carbon dioxide levels to a warmer world comes from the coldest places on earth. Samples of ancient air extracted from deep inside the Antarctic and Greenland ice caps make it clear that CO2 is scarce in the atmosphere during ice ages and relatively abundant during warmer interglacial periods - like...
Another study released this week by the World Wildlife Fund (WWF) examines that problem and its potential future effects - and it's not pretty. The WWF researchers found that Arctic sea ice is melting at a faster rate than expected, and that the massive land sheets in Greenland and parts of Antarctic are vulnerable. The report predicts that global sea level will rise more than 3 ft. by 2100, significantly higher than scientists had previously believed. "What we're finding is truly sobering," says Martin Sommerkorn, the senior adviser for the WWF's Arctic Program. (See the top 10 green...
...freezing to death very quickly - say, a mountaineer who's lost. He still has plenty of food, but it's so cold that his body can't change the food into glycogen long enough to keep him warm and functional. Eventually his body temperature crashes very quickly. (Read about Greenland's melting...
...calories each day. Oh, 5,000 or 6,000 calories a day, sure. With the cold in the Arctic, you do have a really huge calorie need. Even just dug in and trying to survive, you would need probably 3,000-plus calories a day. (See pictures of frozen Greenland...
