protecting shared resources
When sea ice melts during the polar spring the air temperatures increase, the sea ice begins to melt, with the result that the bright white, highly reflective surface of the ice is slowly replaced by open water, which is darker in color and absorbs more energy (heat). The heat absorbed by the water raises ocean and air temperatures further, leading to more rapid melting of the remaining sea ice. This occurrence is an example of
