Even If Emissions Stop, Carbon Dioxide Could Warm Earth for Centuries

Princeton University-led research suggests that even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years. The researchers found while carbon dioxide steadily dissipates, the absorption of heat the oceans decreases, especially in the polar oceans such as off of Antarctica. This effect has not been accounted for in existing research. (Credit: Eric Galbraith, McGill University) Click to enlarge.
Research suggests that even if carbon-dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years.   Thus, it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.
