In the Arctic, temperatures are rising faster than anywhere else on Earth. One reason for this is the melting of snow, as white snow has a special property!
Ninety percent of the sunlight is reflected by the snow, keeping the Arctic cool. As more snow melts, less sunlight is reflected, and the Arctic becomes warmer. This creates a vicious cycle where both effects reinforce each other. In the next 50 years, there will be completely ice-free summers in the Arctic.
