Regardless of the cause, though, the unexpected loss of ice is bad news. Bad news for penguins, who’ll lose large chunks of their habitat, but also bad news for other ecosystems in less intuitive ways: the shape of the ice in the Antarctic affects various ocean currents, and if they change, marine animals in several regions will no longerIt’s also bad news in terms of climate change. More ice means that more heat from the sun is reflected away; if there’s more ocean, that heat gets absorbed.
So, after many years of it being an exception, the Antarctic ice might just have fallen in line with other regions of the world and started to show signals of climate change. The case for cutting
