Great news! Humankind’s greatest-ever engineering project is nearing completion. Soon we will have warmed the Earth enough to get rid of all those pesky ice sheets and other frozen areas. The finish line is in sight.
If we all work together for the next thousand years, we’ll finally reach our goal!
Arctic sea ice is getting thinner and younger. Satellite data and sonar records from submarines show how the ice coverage in the north is getting more and more seasonal. In the past, ice would build up year over year, getting thicker and stronger. But seasonal ice disappears each summer, meaning more open ocean in the summer, and less of the Sun’s energy being reflected back into space.
