World's Oceans Could Rise Higher, Sooner, Faster Than Most Thought Possible

New research shows that consensus estimates of sea level increases may be underestimating threat; new predictions would see major coastal cities left uninhabitable by next century

If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible.

According to the new study—which has not yet been peer-reviewed, but was written by former NASA scientist James Hansen and 16 other prominent climate researchers—current predictions about the catastrophic impacts of global warming, the melting of vast ice sheets, and sea level rise do not take into account the feedback loop implications of what will occur if large sections of Greenland and the Antarctic are consumed by the world's oceans.
