Science, optimism, and the resilience of polar bears in an ever-changing Arctic

Optimism in conservation science — which the Smithsonian says we desperately need (Earth Optimism Summit 21-23 April 2017, apparently a huge success) — means it’s time to acknowledge and celebrate real conservation success stories. The Smithsonian folks probably won’t say it but I will — one of those successes is the recovery of polar bears.

Why not focus on the numerous images of fat, healthy bears rather than the anomalous starving ones?

It’s time to let go of imagined future catastrophes based on pessimistic failures of adaptation (Amstrup et al. 2007, 2008; Atwood et al. 2016; Stirling and Derocher 2012) and acknowledge that polar bears and Arctic seals, just like Pacific walrus (MacCracken et al. 2017; US Fish & Wildlife Service 2017), are resilient species with adaptive capabilities we are only just beginning to comprehend (Crawford and Quakenbush 2013; Crawford et al. 2015; Escajeda et al. 2018; Rode et al. 2014; Stirling and Lunn 1997; Stirling et al. 1975a; Vibe 1965).
