How hot is Antarctica? Constraining crustal heat production
This item is only available electronically. Antarctica is more influential in relation to sea level rise and has a lower level of outcrop than any other continent on the planet. The main factor in Antarctica’s influence on sea level is its reaction to the warming oceans surrounding it, and this is i...
