Poles apart, the Arctic and Antarctic exhibit very different records for sea ice
People might think they’re twins, but the North Pole and the South Pole are really more like distant cousins who, at family reunions, can’t believe they are related.
To visit the North Pole, you have to take a helicopter or plane that lands you on an ice runway just a few meters thick. Beneath your feet stretch several miles of water. Better hope the ice doesn’t crack.
To visit the South Pole, you land on another ice runway, but one solidly anchored to the bedrock beneath. This is why the National Science Foundation can build a huge permanent research station here. No chance you could fall through and drown.
