CANADA: A new study predicting 10 feet of sea level rise by the century’s end isn’t supported by the mainstream scientific community.
A bombshell climate study due out this week warns that sea levels may rise a catastrophic 10 feet (3 meters) by the end of this century, rather than the currently predicted 3 feet (.9 meters). But mainstream climate scientists say the report appears speculative and is not in sync with the leading understanding of melting sea ice.
As a result, the study is unlikely to change leading scientific consensus or affect the current negotiations on a comprehensive global agreement on climate change.
The new study, led by former NASA climate scientist James Hansen (now at Columbia University) is set to be published in the peer-reviewed journal Atmospheric Physics and Chemistry. Hansen and 16 colleagues argue in the paper that increasing melting of the ice sheets over Greenland and Antarctica will lead to a shutdown of the ocean’s currents. That would lead to warm waters trapped under Antarctica, which would increase the melting of ice there (if all the continent’s ice melted, it would raise sea level by around 200 feet).
Hansen’s prediction is more dire than the scenario deemed most likely by the Intergovernmental Panel on Climate Change (IPCC), which foresees no more than 3 feet of sea level rise by century’s end.
