As a professor of chemistry for twenty-six years, I centered my professional life on calculations and experiments. Then in the late 1980s I launched an "encore career" in climate science for diplomacy, including as lead author on five reports by theIt's fair to say that I am deeply versed in the science of climate change and its technological solutions.
. He and his colleagues have developed state-of-the-art methods to measure tree volume, and calculate the weight of trees from their density. Since wood is half carbon by weight, he and I have determined precisely how much carbon mature trees contain between ground and crown. Taller than a 15-story building, Pine 58 has captured nearly 20 tons of carbon dioxide from the atmosphere and stored six tons of elemental carbon in the wood of its trunk, branches, and roots. Additional soil carbon has accumulated as fallen trees, branches, and needles decompose and networks of carbon rich fungi connect tree roots throughout the soil. From root tips to pine cones, this tree is a carbon champion.
