In an alarming yet little-noticed series of recent studies, scientists have concluded that Canada’s precious forests, stressed from damage caused by global warming, insect infestations and persistent fires, have crossed an ominous line and are now pumping out more climate-changing carbon dioxide than they are sequestering.
This fact might be the best illustration I’ve seen of the unexpected consequences of climate change. “Inexorably rising temperatures are slowly drying out forest lands, leaving trees more susceptible to fires, which release huge amounts of carbon into the atmosphere.” What a catastrophic chain of events. How frightening to imagine that global warming is powerful and sinister enough to co-opt the very forces that ordinarily keep it in check.
