Our forests not a net carbon sink
Repeating climate myths doesn’t make them come true. F. Larry Martin suggests, without scientific evidence, that our forests make Canada a net carbon sink (Dec. 10) — so, no need to reduce our extravagant energy use, energy waste and emissions.According to Martin, “Ottawa has not scientifically established that Canada is a net contributor to adverse climate change.” As Natural Resources Canada’s graphs clearly show, Canada’s managed forests were net carbon sinks until 2001. Since then, they have been net sources — adding to our man-made totals, not subtracting.In years when Canada’s forests were carbon sinks, the amount of carbon they absorbed was nowhere near our man-made emissions. This trend will only get worse with warming.In 2007, the Harper government decided to leave Canada’s forests out of its Kyoto equation, because they would be a liability, not an asset.Martin’s argument is null and void. Forests are a natural carbon sink in balance with natural carbon sources. Burning fossil fuels adds long-sequestered carbon to the carbon cycle.Can islanders and coastal dwellers claim the ocean as a carbon offset, too?Absurd argument.Geoffrey Pounder, Rocky Mountain House, Alta.
