The biggest crisis is on the way, in the pipeline, so to speak.
Draconian measures against the oil and gas industry will lead to fertilizer shortages, as will problems in the delivery of existing fertilizer stocks (supply chain problems). These (the war on Oil & Gas, and supply chain disruptions) are the hallmark of the current Administration in Washington, D.C., and are primarily created by policy.
With the former will come (already has) increased prices on anything and everything that uses "fossil" fuels in its creation and transportation, from beanie wienies to toilet paper to condoms. (yes, it hits the consumer coming and going), because the costs of production and transportation have been artificially raised.
In the farm sector, the cost of tillage and harvesting and transport of crops are up. Spare parts costs, similarly, have increased, and fertilizer is harder to get than in previous years. That translates into fewer acres being cultivated, or lower crop yields, which means higher prices.
The climate most affecting food supplies is political, not the planet, and we're not even seeing the worst of this yet.
