Unless warming is slowed, emperor penguins will be marching towards extinction:

Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study from the Woods Hole Oceanographic Institution (WHOI) has found that a warming climate may render them extinct by the end of this century. The study, which was part of an international collaboration between scientists, published Nov. 7, 2019, in the journal Global Change Biology.

"If global climate keeps warming at the current rate, we expect emperor penguins in Antarctica to experience an 86 percent decline by the year 2100," says Stephanie Jenouvrier, a seabird ecologist at WHOI and lead author on the paper. "At that point, it is very unlikely for them to bounce back."

The fate of the penguins is largely tied to the fate of sea ice, which the animals use as a home base for breeding, feeding and molting, she notes. Emperor penguins tend to build their colonies on ice with extremely specific conditions—it must be locked in to the shoreline of the Antarctic continent, but close enough to open seawater to give the birds access to food for themselves and their young. As climate warms, however, that sea ice will gradually disappear, robbing the birds of their habitat, food sources, and ability to raise their chicks.

[...] Under the 1.5 degree [Celsius maximum global temperature increase sought under the Paris Accord] scenario, the study found that only 5 percent of sea ice would be lost by 2100, causing a 19 percent drop in the number of penguin colonies. If the planet warms by 2 degrees, however, those numbers increase dramatically: the loss of sea ice nearly triples, and more than a third of existing colonies disappear. The 'business as usual' scenario is even more dire, Jenouvrier adds, with an almost complete loss of the colonies ensured.

"Under that scenario, the penguins will effectively be marching towards extinction over the next century," she says.

    All the other studies were saying we have record numbers of all kinds of penguins and polar bears. The numbers are so large that the rest of the man made global warming doomist industry, such as the UN-IPCC AR5 report, gave up reporting on their extinction.

    Also independent analysis of the Paris Agreement shows it doesnt affect the temperature of the planet at all, so you cant even get 2 lines into this study without asking the obvious "has this really been Peer Reviewed?" or did they Peer review it themselves?

        They don't look at enough cycles to see the effect. The sun was more active than average for cycles 17-23 (~1933-2009), and less active than average for cycles 12-16 (~1880-1933): https://i.ibb.co/vvdRhnt/sunspots.png [i.ibb.co]

        The drop in activity began last cycle (# 24) and the next one (#25) is expected to be half as active as that: https://www.nasa.gov/feature/ames/solar-activity-forecast-for-next-decade-favorable-for-exploration [nasa.gov]

    Is because emperor penguins are uniquely unable to adapt to their surroundings. Always have been, always will be. Those other penguin species all adapted from their common ancestor, sure, but not those emperor ones, they've always been the same, since forever.

      The problem is the people doing the research are always surprised when an animal shows cleverness superior to their own.

      Eg, these people keep bidding up the price of coastal real estate instead of moving away from the sea they are supposedly worried about rising. If it does rise to the level of flooding I am sure they would just say still and drown unless someone saved them. They expect penguins to be just as stupid.

      It took them millions of years to adapt to those surroundings. Giving them 80 to evolve back into birds might be cutting it a bit short!

        That isn't how evolution works. It is called punctuated equilibrium.

        But these penguins will simply behaviorally adapt in one generation by moving away from where the researchers are bothering them.

        Fish have adapted to massively changed pH levels in rivers downstream of british industry in only decades, and the period of their breeding cycle is comparable to that of penguins. As long as parents are squiring out spawn, you adapt pretty darn quickly to life-threatening situations. Well, the successful ones do, anyway. Read some Gould.

    Just because the penguins only choose ice with specific characteristics, doesn't mean they can't live somewhere else. Naturally, they choose the location most suitable and optimal for their survival. If that location is unavailable, they will live at the next most optimal location. There might be less of them, but I doubt the species is going to die out as a result.
