Why is this Woman Smiling?
Congratulations to the team of scientists led by Darrell Kaufman (Northern Arizona University) on their recent article in the journal Science. The piece (available to subscribers and summarized here) reports that a 2000-year-long cooling trend in the Arctic had been reversed in the 20th century, with four of the five warmest decades in 2000 years occurring between 1950and 2000. The news made headlines in major publications and blogs. The project was funded by the National Science Foundation, and CPS has happily supported Kaufman team visits to lakes around Alaska for lake sediment cores, proxy for paleoclimate information, for years.
NOAA announced plans to sample air in Alaska to determine the natural sources of methane and carbon dioxide—the two most important heat-trapping gases—using a Coast Guard C-130 aircraft. The effort aims to identify the concentrations and sources of major green house gas emissions and make plans for reducing them to stave off global warming.
"Them killer whales, first time people seen them here in the harbor," says Eddie Gruben, 89, of tiny Tuktoyaktuk, NW Territories, Canada. Read about the challenges facing "Tuk" and myriad other polar communities facing a warming Arctic in this Los Angeles Times article.
