Climate models are inconsistent in explanations and underestimate variability

Polar BearA new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth’s atmosphere warms. The models also provide inconsistent explanations of why this variability occurs in the first place.

These discrepancies may undermine the models’ reliability for projecting the short-term pace as well as the extent of future warming, the study’s authors warn. As such, we shouldn’t over-interpret recent temperature trends.
