Climate activist Heidi Cullen told viewers of ABC News this week that recent 'extreme weather' was related to global warming, stating, "When you crank up the heat, when you globally warm the planet, you're going to see more extreme events." What she failed to mention is that the 'extreme weather' is due to La Nina, a cooling of the Pacific Ocean along the equator. Alarmists claim global warming leads to fewer La Ninas, and results instead in a "permanent El Nino" state of warming in the Pacific. This claim has also been repeatedly debunked in the peer-reviewed literature. The claim that warming leads to more extreme events such as storms has also been repeatedly debunked.
