...more clearly visible - it is actually a new phenomenon. In a new study published in the Sept. 4 Science, researchers led by Darrell Kaufman at Northern Arizona University and the National Center for Atmospheric Research constructed a climate record of the Arctic over the past 2,000 years, and found that the region had been cooling for almost all of that time period. Summer temperatures in the Arctic cooled by an average of 0.2 degrees C each thousand years, thanks chiefly to wobbles in the Earth's orbit around the sun that gradually reduced the amount of sunlight hitting...
...then something else happened - us. The Science researchers found that during the 20th century, as human beings began pouring greenhouse gases into the atmosphere, the Arctic stopped cooling and started warming. Even though the Arctic is still gradually getting less sunlight, it's still getting hotter - summer temperatures in the Arctic are 1.4 degrees C higher than they would have been if the cooling had continued unabated, according to the study. The most recent decade recorded - from 1999 to 2008 - was the warmest of the past 2,000 years. The recent warming trend has been so strong that researchers...
Another study released this week by the World Wildlife Fund (WWF) examines that problem and its potential future effects - and it's not pretty. The WWF researchers found that Arctic sea ice is melting at a faster rate than expected, and that the massive land sheets in Greenland and parts of Antarctic are vulnerable. The report predicts that global sea level will rise more than 3 ft. by 2100, significantly higher than scientists had previously believed. "What we're finding is truly sobering," says Martin Sommerkorn, the senior adviser for the WWF's Arctic Program. (See the top 10 green...
...1930s poll revealed, the second-most popular woman in America (just behind Eleanor Roosevelt). Although her show was clearly about a Jewish family, the Goldbergs’ laughter and struggle were accessible and comforting to immigrants throughout the nation, even in the depths of the Great Depression. The humor found in stumbling over English words, the hope of a better future for one’s children, the communal compassion that grew out of many tenement neighborhoods—these were familiar pictures of the American experience for those of the first generation, and Kempner contextualizes this environment with rich...
...recent poll conducted by the Levada Center, a Moscow-based NGO, found that Russians are increasingly pessimistic about their southern fringe. Denis Volkov, a researcher at the center, noted that the survey showed 46% of Russians have faith in the authorities to bring peace to the North Caucasus. Five years ago, that figure was above 60%. Malashenko says there is no end in sight: "We should be prepared for a continuation of this state of latent civil...
