The Australian has a good follow-up today on the Antarctic ice cap, but this section gave me a slight chuckle:
The Antarctic also has an ozone hole above it, which could be acting as a pressure valve, allowing heat to escape the icecap. “It could be that when the ozone hole is fixed, there will be more warming,” Allison says.
Does this mean we can use chlorofluorocarbons again? Create ozone holes to save the planet!
