Photos don’t lie: See the dramatic expansion of Canadian tar sands

Cross-posted from Climate Progress . Extraction of Alberta's energy-intensive tar sands has expanded steadily in recent years, with about 232 square miles now exposed by mining operations. That expansion is expected to double over the next decade, which could mean the destruction of 740,000 acres of boreal forest and a 30-percent increase in carbon emissions from Canada's oil and gas sector. New satellite images show the dramatic expansion that has taken place from 2001 through 2011: Photos: Robert Simmon, NASA/Landsat/USGS So what's the actual impact on the ground? Here's what happens when you turn a carbon sink like the Boreal Forest into a carbon-spewing pit of tar sands: Photos: Peter Essick, National Geographic
