But even here, his statement is an exaggeration, since scientists who study the cryosphere are predicting that the Arctic Ocean could be ice free in 20 years. (Some scientists predict sooner.) This would be ominous enough, since it could theoretically push the climate system across a tipping point, leading to dramatic, sudden changes.
