The Intertwined Food and Climate Emergency: Heeding ScienceEnvironment • September 21, 2025 • Judith DeutschThis is an astonishing world. These disasters are less than what is in store because of thermal inertia, the lag in the Earth’s adjustment to carbon dioxide (CO2) concentration. Unique at this historical time is the speed at which carbon dioxide is being emitted, unlike the slow build-up in previous mass extinctions. Loss of topsoil’s absorption of carbon dioxide may contribute as much as 2 gigatonnes of carbon annually, around 20% of global emissions. Who knew that being against ‘CO2 is plant food’ is the same as committing genocide?” (Some science writing is entertaining!)
