ScienceDaily (May 15, 2008) — U.S. Secretary of the Interior Dirk Kempthorne announced May 14 that he is accepting the recommendation of U.S. Fish and Wildlife Service Director Dale Hall to list the polar bear as a threatened species under the Endangered Species Act (ESA). The listing, the government says, is based on the best available science, which shows that loss of sea ice threatens and will likely continue to threaten polar bear habitat.
... a lack of sea ice that, strangely enough, suddenly doesn't exist anymore.
On a global basis, world sea ice in April 2008 reached levels that were “unprecedented” for the month of April in over 25 years. Levels are the third highest (for April) since the commencement of records in 1979, exceeded only by levels in 1979 and 1982. This continues a pattern established earlier in 2008, as global sea ice in March 2008 was also the third highest March on record, while January 2008 sea ice was the second highest January on record.
Does anyone have an explanation? Incidentally, while (prior to this year) northern hemisphere sea ice had been declining at 2.8% ... per decade ... southern hemisphere sea ice has been increasing at 4.2% per decade. Will we be removing the designation if over the next year or two sea ice remains at higher levels? Right, silly question.
This just in: The earth's climate changes, and always has.
