In 2009, the Department of Interior interpreted “foreseeable future” as the timeframe over which the Services can “reasonably rely on predictions about the future in making determinations about the future conservation status of the species” (Department of Interior, 2009). The species has existed over geological time, surviving previous glacial and interglacial periods probably by migrating to suitable habitat as conditions change (Younger et al. The short‐distance dispersal scenario allows for regional movements among colonies, while long‐distance dispersal creates a more connected meta‐population across the entire range (see Jenouvrier et al. C] which conservatively assumes that sea ice concentrations will remain at a steady level for 50years from 2050 to 2100 (Figure ​ (Figure3).

are in close agreement with historical total cumulative CO 2 emissions and the best match out to 2050 under current and stated policies (Schwalm et al. in our metapopulation model to capture these potential dynamics observed over geological and historical scales (Cole et al. we also consider nine dispersal scenarios combining different dispersal rates, behaviors, and distances. Regional number of breeding pairs of emperor penguins from 2009 to 2100 projected for two climate scenarios (plain lines 4. The Community Earth System Model (CESM) large ensemble project: A community resource for studying climate change in the presence of internal climate variability.Second, we classified each year as extreme or not, by comparing the sea ice concentration in that year to T si. To diagnose uncertainties related to natural climate variability—a noise from unforced variability generated internally within the climate system (e.

The study was designed to assess the 3Rs (Figures ​ (Figures8, 8, ​ ,9, 9, ​ ,10) 10) and inform policymakers about whether the emperor penguin warrants listing under the ESA and we discuss recommendations and ESA protections for emperor penguin.Natural systems provide the ecosystem services that support people and sustain their livelihoods, as well as supporting the wildlife that form an intrinsic part of these systems. Here we present important concepts related to the protection of species endangered by climate change, using as an example the emperor penguin, a flagship species threatened by sea ice decline.
