Reining in global carbon dioxide emissions would reduce the risk of major changes in the Antarctic but still not prevent them. Once we start losing Antarctic sea ice, we set in a self-perpetuating process. Even if we stabilise the climate, we will still lose Antarctic sea ice over many centuries to come.
"To keep Earth habitable, humanity must recognize the value of Antarctica and seek to save it from irreversible damage.
Far from being a remote, isolated continent, Antarctica is integral to Earth’s climate and life-support systems.
Its vast ice sheet stores more than 90% of the planet’s surface fresh water and influences sea levels, circulation of the atmosphere and how much sunlight the planet reflects.
Around Antarctica, the Southern Ocean acts as the lungs of the deep sea, accounting for roughly 40% of the global ocean’s uptake of carbon dioxide emissions generated by human activities, shaping how seawater mixes and distributes nutrients to support marine life around the globe."

Now we have...

A few random marine facts I’ve learned:
- some southern sea otters eat so much purple sea urchin that their skulls turn purple
- the whales in Monterey bay don’t need to do bubble net feeding because there is so much food, unlike the situation for whales elsewhere
- California sea lions work with humpback whales where the sea lions corral the fish, the whales open their mouths and feed, and any fish that comes out stunned is picked up by the sea lions
- a sea urchin’s mouth is also called Aristotle’s Lantern (watch a video)
- Mola Mola eventually evolved the ability to retract their eyeballs into their sockets so that when they were lying on the surface, having their parasites cleaned by gulls, they won’t peck out their eyes too
- the orca in Monterey don’t eat the whales, but they like to nip at them. So some whales have rake marks on their bodies that continue to look obvious and visible even if they got them as calves
- whale milk has the consistency described as like if cottage cheese was also toothpaste, and is ejected directly into calves’ mouths with minimal loss in seawater
- sunflower sea stars are carnivores
