There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the U.S. National Snow and Ice Data Center reported.
Satellite measurements showed 5.2 million square kilometres of ice in the Arctic, falling below the Sept. 21, 2005, record minimum of 5.3 million square kilometres, the agency said...
But, Serreze said in a telephone interview, while some natural variability is involved in the melting "we simply can't explain everything through natural processes."
"It is very strong evidence that we are starting to see an effect of greenhouse warming," he said.
Critics often argue that you can't trust the computer models, associated with global warming. A feather in the cap for denialists, the models are wrong, the situation is actually WORSE:
The puzzling thing, he said, is that the melting is actually occurring faster than computer climate models have predicted.
Several years ago he would have predicted a complete melt of Arctic sea ice in summer would occur by the year 2070 to 2100, Serreze said.
But at the rates now occurring, a complete melt could happen by 2030, he said Friday.
There will still be ice in winter, he said, but it could be gone in summer.
Maybe Canada won't need those icebreakers afterall.
