Within the next several decades, ice over the Arctic will completely disappear during the summer. That’s just one of the clear and dramatic predictions to come from models developed by the Climate Ocean and Sea Ice Modeling (COSIM) program at the Department of Energy’s Los Alamos National Laboratory.

Additionally, “The models now predict globally an average surface temperature rise of 2 to 4 degrees Celsius over the next 100 years,” says the program’s project manager, Philip Jones. And the oceans account for more than 70 percent of the Earth’s surface.
