Climate models disagree on why temperature 'wiggles' occur

Most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. They also provide inconsistent explanations of why these wiggles occur in the first place, a new study finds. These inconsistencies may undermine the models' reliability for projecting the short-term pace and extent of future warming, and indicate that we shouldn't over-interpret recent temperature trends. The study analyzed 34 models used in the most recent IPCC assessment report.
