THOUGHT EXPERIMENT: Some 70% of people, depends how you ask, accept the global emergency. Climate system destabilisation is one aspect, declining biodiversity and increasing pollution is another. I ask: what would actually *break* if humanity responded decisively? 1/

I previously 👇 documented 20 mechanisms through which climate change is 𝘢𝘭𝘳𝘦𝘢𝘥𝘺 disrupting food production.
Below I am adding to the list including several newly documented mechanisms.

Several primary impacts relate to altered soil & plant chemistry & biology:
1. Disruption of the phosphorous cycle - the second most vital element for plants after nitrogen
2. Decreased content of key nutrients in major
3. Reduced chill hours required for many plants to bloom normally in the
Other additional primary impacts include:
4. Fossil fuel pollution impacts on crops - this is not a result of climate change per se, but is included since it is due to the same root cause (fossil fuel use):
