Why Antarctica Is Getting Taller
An anonymous reader quotes a report from Live Science: Bedrock under Antarctica is rising more swiftly than ever recorded -- about 1.6 inches (41 millimeters) upward per year. And thinning ice in Antarctica may be responsible. That's because as ice melts, its weight on the rock below lightens. And over time, when enormous quantities of ice have disappeared, the bedrock rises in response, pushed up by the flow of the viscous mantle below Earth's surface, scientists reported in a new study. These uplifting findings are both bad news and good news for the frozen continent. The good news is that the uplift of supporting bedrock could make the remaining ice sheets more stable. The bad news is that in recent years, the rising earth has probably skewed satellite measurements of ice loss, leading researchers to underestimate the rate of vanishing ice by as much as 10 percent, the scientists reported. The findings were published in the journal Science.Read more of this story at Slashdot.
