SINGAPORE — A team from the Chinese Academy of Sciences trekked across frigid highlands in Tibet to confirm a significant recent discovery about climate change. They drilled and analyzed five ice cores from various locations on the Tibetan Plateau to find that the concentration of black carbon, or soot, in the ice has increased by two to three times since 1975.
At Zuoqiupu Glacier, on the southern edge of the plateau downwind from the Indian subcontinent, black carbon deposition rose by 30 percent between 1990 and 2003.
What are the implications of these and other related findings in recent years by numerous researchers from different countries and scientific agencies?
