There is a popular notion in the media that human-induced global warming will result in the onset of a new ice age. In their Perspective, Weaver and Hillaire-Marcel refute this view, explaining that global warming is unlikely to dramatically alter the North Atlantic ocean circulation. They also emphasize that elevated levels of atmospheric carbon dioxide lead to summer temperatures that do not allow glacier formation and growth.
