There are so many other confounding things going on: hunting, not hunting, hunting or not of animals that prey on a species, hunting or not of animals that compete for food with a species, reintroductions of animals that prey on or compete, increased food due to climate change, new ranges opening up due to climate change, other species invading new territories, being either predators or new food sources. There are threats misattributed to cc, like the bees — probably killed by sprays that are now stopped, and bees are back, climate change notwithstanding.

Penguins and ice seem to go together, but Antarctica is huge, the ice shelves are massive, and penguins seem to do just fine on land of which there is plenty under the ice — they just don’t photograph so well on land.
