More overwhelming evidence that Pachauri and Pelosi should radically redesign the US economy?: Temperature for a year or two near 14 narwhals warmer than expected

Arctic Whales Assist Scientists Taking Ocean Temperatures
The data recorded by the creatures on their mile-deep dives in 2006 and 2007 showed a continuing temperature increase, the National Oceanic and Atmospheric Administration and the American Geophysical Union reported today (Oct. 27).
During a study into the feasibility of using these whales as lab helpers, researchers found that temperatures were nearly 1.8 degrees Fahrenheit (1 degree Celsius) warmer on average than what climatology data said. Whale-collected temperatures also demonstrated that the winter-surface isothermal layer (a layer of constant temperature) was thinner by 160 to 260 feet (50 to 80 meters) than in the climatology data.
Scientists themselves have had limited opportunities to measure the temperatures of Baffin Bay during winter because of dense ice, harsh conditions and the cost of mounting such missions. Instead researchers over the past decade have been using climatology data (long-term historical average observations) rather than direct ocean measurements.
