Abstract:

This talk overviews changepoint issues in climatology. Changepoints (inhomogeneities) are ubiquitous features in climatic time series, arising, for example, when stations relocate or instrumentation is changed. Changepoints confound many inference problems and are very important data features. Here, we show why changepoint information is essential in making accurate trend conclusions. Examples are given where inferences are questionable when changepoints are ignored. The talk will delve into two recent contentious climate issues: 1) the recent increase in Atlantic Basin hurricanes; and 2) the “warming hole” (lack of warming) seen in the Eastern United States.
