Here's a global warming question.

If you were ready to dismiss it in the face of record ice buildup over the winter (a misnomer since so much had previously melted it was inevitable it would fill that space back up during winter) now that it's ALL GONE and melting faster than ever does that mean it's back on again?

But now it is down to levels seen last June, at the beginning of a summer that broke records for sea ice loss.

 

Scientists on the project say that much of the ice is so thin that it melts easily, and the Arctic may be ice-free in summer within five to 10 years.

"We had a bit more ice in the winter, although we were still way below the long-term average," said Julienne Stroeve from NSIDC in Boulder, Colorado.

 

"So we had a partial recovery; but the real issue is that most of the pack ice has become really thin, and if we have a regular summer now, it can just melt away," she told BBC News.

 

In March, Nasa reported that the area covered by sea ice was slightly larger than in 2007, but much of it consisted of thin floes that had formed during the previous winter. These are much less robust than thicker, less saline floes that have already survived for several years.

Wow, is this a normal cycle?

Global warming is cyclical. In the early 1900's, scientists thought we were going through global warming. In the 70's, scientists thought we were going through global cooling. Now, scientists think we are going through global warming. I expect in 20 years scientists will, yet again, change their minds.
