5. What does polar ice do to the sunlight that strikes it? How does this help reduce global warming? What is happened to the sunlight energy that strikes ocean water? How does this speed up the melting of ice?
Shiny polar ice reflects 90 percent of the sunlight that strikes it back into space. Liquid water, on the other hand, retains 90 percent of the energy it receives. The more energy it absorbs, the hotter it gets. [ The hotter the water, the faster the ice melts. The melting ice frees a relatively warm layer of Atlantic water, which, as Ruth Curry from Woods Hole Oceanographic Institute told
"Time," rises into the atmosphere and releases more heat.
