Emperor penguin ESA listing in 2022 used Antarctic sea ice models known to be flawed

While Arctic sea ice has declined remarkably since 1979, Antarctic ice has been unexpectedly stable. Experts acknowledge that existing climate models–which assume that CO2 emissions drive global sea ice loss–had predicted Antarctic sea ice would have declined over the last several decades–and would decline even more in the future. They’ve finally admitted they were wrong.

John Turner (British Antarctic Survey) and Josifino Comiso (NASA) in a NATURE paper in 2017:

Current climate models struggle to simulate the seasonal and regional variability seen in Antarctic sea ice.

Emperor penguins join polar bears on ESA list of threatened species based on flawed climate models

Yesterday, the US Fish and Wildlife Service announced it will classify the Emperor penguin as ‘threatened’ with extinction under its Endangered Species Act (ESA) based on what are known to be flawed climate models, to take effect next month. This is despite the fact that Emperor penguin numbers increased between 2009 and 2019, an IUCN Red List reassessment in 2019 did not reverse its 2018 decision (still listing it as ‘near-threatened’, not ‘vulnerable’), and member-nations refused earlier this year to enact an Antarctic Treaty to protect the birds. Conservation activists of all stripes are filled with glee at this bettter-than-nothing decision for a species nowhere near extinction because it means more money for them.

Bottom line: An article by the US National Public Radio (25 October 2022) admits the real reason for this listing:

Though emperor penguins are not found naturally in the U.S., the endangered species protections will help increase funding for conservation efforts. U.S. agencies will also now be required to evaluate how fisheries and greenhouse gas-emitting projects will affect the population…
