A team of scientists from the Carnegie Institution for Science's Department of Global Ecology and the USDA Forest Service's Pacific Southwest Research Station (PSW) has developed new, more accurate methods for mapping carbon in Hawaii's forests.  The team estimated a total of 28.3 million tons of carbon sequestered in above ground woody vegetation on the island, which is 56 percent lower than estimates by the Intergovernmental Panel on Climate Change that were not intended to resolve carbon variation at fine spatial scales. http://www.sciencedaily.com/releases/2011/03/110314172329.htm
