Toward a More Reflective Planet

The last time the atmosphere held as much carbon dioxide as it does today was about three million years ago – a time when sea levels were 10-30 meters higher than they are now. Climate models have long struggled to duplicate those large fluctuations in sea levels – until now. Indeed, for the first time, a high-quality model of Antarctic ice and climate has been able to simulate these large swings. That is smart science, but it brings devastating news.
