Question

Extensive and unusual cold snaps have occurred here recently. Is this evidence that global warming is lessening or not occurring? No—although the long-term trend is for warming, short-term weather patterns can still be variable. No—melting of glaciers and ice caps is making the oceans cooler, which can cause cold snaps. Yes-- if global warming really were occurring, cold snaps wouldn’t happen. Yes—due to global warming, weather patterns should be become less—not more—variable.
