Cold Facts On Rising Seas By Andrew Bolt Wednesday, March 28, 2007 at 12:33pm ABC Science Show presenter Robyn Williams panics about global warming: Andrew Bolt: I ask you, Robyn, 100 metres [of sea level rises] in the next century...do you really think that? Robyn Williams: It is possible, yes. It is possible, no, actually. Now Glaciologist Nikolai Osokin of the Russian Academy of Science reassures Williams about global warming: If all ice on the earth melted, the level of the oceans would rise by 64 meters. Many coastal cities would be under water, and so would the Netherlands, a significant part of which lies below sea level. However, the Dutch and the rest of the planet may rest assured: this hypothetical catastrophe could not take place anytime within the next thousand years And is there actually any reason to believe Antartica, which has not warmed and is home of 90 per cent of the world's land-based ice, will melt clean away? The temperature rise of 3-6 degrees Celsius over the next century promised by pessimists could not have a significant influence on the Antarctic, where the average temperature is less than 40 degrees below zero.

The National Aeronautics and Space Administration has developed 3-D computer animation showing the retreat of the west Antarctic ice sheet over 20,000 years, speeded up into a few minutes of dramatic video footage. "The purpose of the visual is to emphasize the changes that have taken place," said Robert Bindschadler, a glaciologist at the NASA Goddard Space Flight Center in Maryland. "During the last 20,000 years, the west Antarctic ice sheet lost two-thirds of its mass and raised the sea level 10 meters. It still contains enough ice to raise the sea level by another 5 meters if it were to lose the remainder of its mass,' Bindschadler said. During the last 30 years, scientists have become increasingly concerned about the effects global warming might have on the west Antarctic ice sheet. Specifically, some researchers have expressed concern that rapid melting of the sheet could contribute to a catastrophic rise in sea levels around the world. The majority of the west Antarctic ice sheet sits atop dry land, while the east Antarctic ice sheet is grounded below sea level. Changes in the east Antarctic sheet would have little effect on sea levels since the ice displaces water, but a complete melt of west Antarctic ice would pour new water into the oceans. Scientists say the ice sheet has lost two-thirds of its mass Bindschadler said there is evidence that the west Antarctic ice sheet may have melted and reformed several times during the past 11 million years. The computer animation begins with Antarctica at the peak of the last Ice Age about 20,000 years ago, and shows the gradual shrinking of the west ice sheet. "About 12,000 years ago, it began a dramatic retreat," Bindschadler said. "We're not sure if the retreat is still taking place -- that's one of the main questions we're trying to answer." |
