IS THERE ENVIRONMENTAL REPERCUSSION DEVELOPING FROM THE XL-PIPELINE, HERE IS SCIENTIFIC FACT -- not political agenda facts: There are two reasons Keystone has become a political lightning rod. The most important factor is what development of the oil sands—or tar sands—as they’re called by opponents—means for global warming. Extracting bitumen—a low-grade type of petroleum -- from the region is more akin to mining than conventional oil drilling, and the process of extracting crude or bitumen from oil sands emits roughly 15 percent more greenhouse gas emissions than the production of the average barrel of crude oil used in the United States. NASA climate scientist James E. Hansen, who just retired from his federal job so he could become a full-time climate activist, said if all the oil was extracted from the oil sands it would be “game over” when it came to the effort to stabilize the climate.
