Why is it colder at the South Pole than the North Pole?
A recent report says the Arctic may be ice-free by 2040. The Antarctic is also melting, albeit far slower, and in a less regular pattern. Why do the two poles react so differently in the face of climate change?
Temperatures in the Arctic region have reached record highs in the past days. Climate scientists blame the development on global warming.
Experts across the world are alarmed at how small the area covered by sea ice has become. They are saying the change is unprecedented - and they're calling for action.
