The Newhouse shelter in Kansas City has helped thousands of abused women and their children over the past 37 years. But last month, the women were forced to move out and the staff started looking for new jobs. The reason was simple. While the need was there, the money was not. Dwindling charitable contributions tied to a broad U.S. economic slowdown mean fewer resources and hard choices for charities across the country.
"People are holding tight to their money," said Newhouse President Leslie Caplan, who estimated charitable contributions were down ＄200,000 this year compared to last year. That, combined with cuts in government grants, has severely squeezed the center’s ＄1.3 million budget.

[单项选择]Rainforests may store much less carbon than we thought. It could be time to dramatically revise our estimates following the discovery that apparently similar forests hold vastly different amounts of the stuff. The finding is important because there are plans for governments worldwide to compensate tropical countries for protecting their forests as "carbon sinks" to curb global warming. If carbon cannot be counted, then dollars cannot be disbursed (支付).
Greg Asner of the Carnegie Institution for Science in Stanford, California, and colleagues say they used satellite mapping, laser probing of forest undergrowth from aircraft and local ground surveys across a large area of Peruvian rainforest to crack the problem of estimating how much carbon is locked up in forests. But the new technique has revealed a large, previously unknown variability in the density of carbon stored in apparently similar forests.

A. be provided with valid data on forest carbon
