Since the 1990s, local residents from around the Arctic have reported changes in weather predictability. Examination of environmental measurements have not, until now, helped describe what the local inhabitants have been reporting, in part because prior studies did not focus directly on the persistence aspect of weather. Here we show that there is evidence of changes in persistence in weather over the last two decades for Baker Lake, Nunavut, Canada. Hourly data indicate that for local spring, the persistence of temperature has changed dramatically in the last 15 years with some years showing a strong drop in day-to-day persistence in the local spring afternoons, somewhat at odds with changes in persistence on a more global scale. Changes in daily persistence may have implications for human health, agriculture, and ecosystems worldwide. More importantly, the approach of merging indigenous knowledge with scientific methods may offer unexpected benefits for both. (C) 2010 Elsevier Ltd. All rights reserved.
