Since roughly 1880 the Earth has warmed by 1 deg C, many times faster than any warming episode in the past 65 million years of Earth’s geological history. We will need to remove hundreds of gigatons of carbon dioxide (CO2) from the atmosphere by the end of the twenty-first century to keep global warming below 2°C within the constraints of the global carbon budget. In a recently published paper we explore the Tweed River valley in north-eastern New South Wales as a 'natural laboratory' to test the idea that carbon captured during the erosion and weathering of volcanic rocks could be a viable mitigation strategy against global warming.
