Potential threat is overlooked

While much public attention rightly focuses on carbon dioxide and methane as greenhouse gases, another potent threat often goes overlooked - nitrous oxide.

- Professor Dave Evans

This gas, largely produced by agricultural practices, has nearly 275 times the global warming potential of carbon dioxide and remains in the atmosphere for over a century. Emissions of nitrous oxide from human activities went up 40 per cent in the four decades from 1980 to 2020.
