New York Times article "Arctic Melt Unnerves the Experts"

Claim:

Scientists can hardly fathom the amount of deterioration in the Arctic Circle this year. The ice has melted so much more than other annual averages, that scientists are beginning to wonder how much longer until more drastic changes occur. Can this phenomenon be ascribed to anything besides overactive, overindulging humans? Unfortunately, scientists would give the disappointing "no" to that answer. A bigger concern, though, is next year's summer and its melting period, because this year the ice deficit is so low.

Evidence:

1. "The Arctic ice cap shrank so much this summer that waves briefly lapped along two long-imagined Arctic shipping routes, the Northwest Passage over Canada and the Northern Sea Route over Russia."
2. "Astonished by the summer’s changes, scientists are studying the forces that exposed one million square miles of open water — six Californias — beyond the average since satellites started measurements in 1979."
3. "...this winter’s freeze is starting from such a huge ice deficit."

Why the claims are warranted:

The first two claims cite scientific evidence that is warranted by the facts that are provided (i.e. "six californias," "beyond the average since satellites started measurements in 1979"). The third fact also contains scientific evidence, but shows to us that it would make sense why this becomes a snowball (pardon the pun) effect. Besides that, we believe these three because they are scientific facts and because this print source (NYTimes) is credible.
