IB ESS 5.1.21 (HL) Carbon release from soils
Practise explaining how soils release carbon as methane or carbon dioxide and how warming, farming and drainage can amplify change.
How this is tested
- explain how wetland drainage or agriculture can increase methane or CO2 release from soils
- link soil carbon release to positive feedback and possible climate tipping points
