Arctic ice shrinks to all-time low; half 1980 size

...satellite tracking."On top of that, we're smashing a record that smashed a record," said data center scientist Walt Meier. Sea ice shrank in 2007 to levels 22 percent below the previous record of 2005.Ice in the Arctic melts in summer and...
Scientists: It's not too late yet for polar bears

...wouldn't say that we can rule out a tipping point, but it does show that a tipping point isn't inevitable," said Walt Meier, a senior scientist at the National Snow and Ice Data Center in Boulder, Colo. But that all hinges on reducing greenhouse...
Arctic sea ice misses record for the fewest miles covered

...last year. "This year's wintertime low extent is another milestone in a strong downward trend," said researcher Walt Meier. "We're still seeing near-record lows (in sea ice) and higher-than-normal temperatures, and we expect this...
Arctic ice melts to second-lowest level in recorded history an area that covers just the region west of the Mississippi River, said Snow and Ice Data Center senior scientist Walt Meier.The University of Bremen in Germany, which uses a different satellite sensor and has been monitoring levels since...
Arctic sea ice melt comes close, but misses record

...though the sea ice didn't retreat this year as much as last summer, "there was no real sign of recovery," said Walt Meier of the snow and ice data center. This year was cooler and other conditions weren't as bad, he said. "We're kind...
