World's Largest Outdoor Climate-Change Experiment

22 July 2005 - 8:00am

Despite opposition from local residents, an eight-year long experiment deliberately pollutes thousands of trees to study the impact of future global warming.

"Started in 1997 on U.S. Forest Service land about 150 miles northwest of Green Bay, it is one of four such outdoor projects that the Department of Energy is funding. The pollution that scientists are recreating is one and a half times that found in northern Wisconsin, "or about the same levels on a clear day in Los Angeles," Karnosky said...

Some environmentalists and local residents are protesting the project -- not because of the research, but because of where it is taking place."

As an alternative to burial, cremation is no longer green enough, say some environmentalists, because it releases smoke and mercury into the atmosphere.
