Pacific Hot Spells Shifting as Predicted in [an allegedly] Human-Heated World - NYTimes.com

I asked Lee and McPhaden how a connection to greenhouse-driven warming could be made, given the possibility that the Pacific shift could be the result of long-term oscillations in conditions in the ocean unrelated to the buildup of heat-trapping greenhouse gases in the air.
