H. James Simpson, a geochemist who pioneered important studies of water pollutants in the Hudson River and abroad, died May 10. He had been affiliated with Columbia University’s Lamont-Doherty Earth Observatory for 50 years. The cause was Parkinson’s disease, said his family; he was 72.

The United Nations has awarded Taro Takahashi, a geochemist at Lamont-Doherty Earth Observatory, its highest honor for environmental leadership, the Champions of the Earth award, for his research on the oceans’ uptake of carbon dioxide and its implications for global warming. He was presented with a trophy and a $40,000 prize on Thursday, April 22, in a ceremony in South Korea.

The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions...

Proposed Method Would Speed Natural Reactions a Million Times
Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.
