Looming Warming Spurt Could Reshape Climate Debate
By John Upton Humanity is about to experience a historically unprecedented spike in temperatures. That’s the ominous conclusion of a vast and growing body of research that links sweeping Pacific Ocean cycles with rates of warming at the planet’s surface — warming rates that could affect how communities and nations respond to threats posed by climate change. Papers in two leading journals this week reaffirmed that the warming effects of a substantial chunk of our greenhouse gas pollution have been avoided on land for the last 15 to 20 years because of a phase in a decades-long cycle of ocean winds and currents. With Pacific trade winds expected to slacken in the years ahead, the studies warn that seas will begin absorbing less of global warming’s energy, and that some of the heat they’ve been holding onto will rise to the surface. Extreme heat can exacerbate drought. Credit: Kecko /Flickr “Their results make sense to me, and are consistent w...
