"Evaluating climate model performance in the tropics with retrievals of water isotopic composition from Aura TES." Ahead of each major IPCC report, the world's climate modeling centers run a set of scenarios for the future, calculating how different global emissions paths will alter the climate. AbstractThe climate is dynamic and complex, affected by processes happening at the scale of a cloud droplet to the size of the planet. Gavin Schmidt says there’s nothing really wrong with climate models — in fact, “they’ve done a pretty good job of predicting what has happened.” One reason they aren’t more precise, he says, is people.
