Converting methane into carbon dioxide could help turn the tide of climate change, according to Stanford scientists who propose that turning one greenhouse gas into another may be a profitable way to combat global warming. While the idea of intentionally releasing carbon dioxide into the atmosphere may seem counter-intuitive, swapping methane for carbon dioxide is a significant net benefit for the climate, according to the study published in the journal Nature Sustainability. "If perfected, this technology could return the atmosphere to pre-industrial concentrations of methane and other gases," said Rob Jackson from Stanford University in the US. In 2018, methane -- about 60 per cent of which is generated by humans -- reached atmospheric concentrations two and a half times greater than pre-industrial levels, previous studies have shown. Although the amount of carbon dioxide in the atmosphere is much greater, methane is 84 times more potent in terms of warming the climate system over ..
