Climate Tipping Point Coming Faster Than IPCC Thought


Two reports released recently—one from the UN’s Environmental Programme and the other by the World Bank—warn that dramatic, irreversible climate shifts are coming faster than the Intergovernmental Panel on Climate Change (IPCC) anticipated. In the IPCC’s last report, published in 2007, it expected that global sea levels could rise up to two feet: the UN document says it may be more like six feet. More disturbingly, it says that “we may have already passed tipping points that are irreversible within the time span of our current civilization.”

Although we’ve covered tipping points in previous issues of Mother Jones, it’s still disturbing to hear the UN say they may have already been tipped, and not in our favor. For those who are interested, the World Bank report goes into further detail about tipping points as seen in the Andes, coral reefs, Gulf of Mexico wetlands, and Amazonian forests that may or may not be too far gone to do anything about.

FACT:
