Missing Sea Ice
Here is a graph of the sea ice in the Northern Ocean published today, at least using information from the federal government (the National Snow and Ice Date Center up the road a bit in Boulder, CO). It says there is just below 8 million square kilometers of ice just now. That's worse than the 'average' between 1979 and 2000 but better than last year (which was alarmingly low).
The next graph is from the University of Illinois and it shows only about 5.3 million square kilometers. Where did more than two and a half million kilometers of sea ice go? Notice too that the government had 14.4 at the beginning of April, while the college showed less than 13.4. Both show about a million square kilometer more ice now than at this time last year. Let's see if the satellite photo composite shows that difference.
Yeah, it looks like there is a lot more ice, especially along the northern coast of Siberia. Two months of ice melting northern warmth to go before the sea ice begins to form again in early Autumn.
