A group of US scientists have warned that a UN panel on climate change underestimated the scale of sea-level increases this century resulting from global warming, the Independent reported on Tuesday.
The six scientists cautioned that the Earth is in “imminent peril” in a 29-page article published in the July 15 issue of the Philosophical Transactions of the Royal Society A. “Recent greenhouse gas emissions place the Earth perilously close to dramatic climate change that could run out of control, with great dangers for humans and other creatures,” wrote the group led by James Hansen, the director of Nasaâ€™s Goddard Institute for Space Studies.
They predict in their paper, “Climate change and trace gases” that sea levels may rise by several metres by 2100, according to the Independent. That compares to a forecast from the UN Intergovernmental Panel on Climate Change published in a February report that predicts sea levels increasing between 18 and 59 centimetres. They also implicitly criticise the UN IPCC for underestimating the scale of sea-level rises this century as a result of melting glaciers and polar ice sheets.
The other scientists involved in the paper were Makiko Sato, Pushker Kharecha and Gary Russell, also of the Goddard Institute, David Lea of the University of California at Santa Barbara and Mark Siddall of the Lamont-Doherty Earth Observatory at Columbia University in New York.
They say that the Earth today stands in imminent peril and nothing short of a planetary rescue will save it from the environmental cataclysm of dangerous climate change.
The six scientists from some of the leading scientific institutions in the United States have issued what amounts to an unambiguous warning to the world: civilisation itself is threatened by global warming.
They describe in detail why they believe that humanity can no longer afford to ignore the “gravest threat” of climate change.
