The President has delayed the Keystone Pipeline Project for almost as long as he's been in office. That pipeline would have brought oil from Canada for refinement throughout the central and southern United States; and it now seems to be in jeopardy. The Canadian government has just approved a trans-Canada pipeline that would move the oil that was originally destined for the Keystone Pipeline to their Pacific ports for shipments to Asia; primarily China.
So, instead of counting on our friendly neighbor to the north to supply us with oil, that neighbor has been forced to help China instead. And, that oil, that would have been more cleanly refined in the U.S., will probably be processed in a country whose CO2 emission laws hardly exist. As a result, Obama is actually responsible for creating more CO2 pollution than if it had been processed here in the US. Is this what going it alone on Climate Change is all about?
