There is finally some good news from environmental scientists studying climate change: as the earth gets warmer, ancient redwood trees are thriving. The huge trees that dot the California coast and the Sierra Nevada mountains soak up carbon dioxide from burning fossil fuels, keeping the potentially harmful greenhouse gas out of the atmosphere. Despite the warming climate, redwood trees are growing faster than at anytime over the last century, according to a report issued today by the Redwoods and Climate Change Initiative.
