"SINGAPORE - Even greater efforts to strip carbon dioxide from the atmosphere will fail to avert climate change catastrophe as rising global temperatures threaten to cross a key threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit), scientists said on Wednesday.
The Intergovernmental Panel on Climate Change (IPCC) has said carbon dioxide removal (CDR) could help slow warming by reducing greenhouse gas already accumulated in the atmosphere, and even temperatures, especially if 1.5 C is exceeded.
However, even if removing carbon dioxide works, it can do nothing to mitigate other aspects of climate change, from sea level rises to changes in ocean circulation, scientists said in research published in the journal Nature on Wednesday.
"Even if you've brought temperatures back down again, the world we will be looking at will not be the same," said Carl-Friedrich Schleussner of Austria's International Institute of Applied Systems Analysis, one of the paper's authors."
