Robust warming projections despite the recent hiatus (original) (raw)

The hiatus in warming has led to questions about the reliability of long-term projections, yet here we show they are statistically unchanged when considering only ensemble members that capture the recent hiatus. This demonstrates the robust nature of twenty-first century warming projections.

We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP, and we thank the climate modelling groups for producing and making available their model output. For CMIP, the US Department of Energy's Program for Climate Model Diagnosis and Intercomparison provides coordinating support and led the development of software infrastructure in partnership with the Global Organization for Earth System Science Portals. The analysis in Figure 1 was inspired by work completed as part of the Australian Academy of Science Climate Change Q&A Report, led by the late Professor Michael Raupach. It is to his memory that this paper is dedicated.
