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 https://eurekalert.org/pub_releases/2020-09/ru-gwt091120.php

2. Decreased content of key nutrients in major crops https://www.sciencedaily.com/releases/2019/07/190718085308.htm
3. Reduced chill hours required for many plants to bloom normally in the spring https://www.npr.org/sections/thesalt/2020/02/17/805688641/warm-winters-threaten-nut-trees-can-science-help-them-chill-out
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): https://twitter.com/JimBair62221006/status/1307120001116188673

5. Severe crop damage from wind storms - in this case, ~$7.5 Billion in damage from a single storm: https://bit.ly/2V9Rbqz
6. Also wind (& heat) related - increasing prevalence of ‘furnace winds’.

7. And another phenomenon that is an intensification of the existing- “flash droughts” https://twitter.com/JimBair62221006/status/1244013330244620288
New secondary factors include:
1. Hoarding - even at the national/international scale - something we have disturbingly see with #COVIDー19.

2. Farmer mental health taking a toll - in the U.S. ( https://bit.ly/3fUDrtn ) and internationally, in extreme cases leading to suicide ( https://bit.ly/39uhXlw )
Most worryingly, we are now seeing a rapid increase in frequency of extreme weather, whereby farmers are being devastated by 2, 3 or sometimes more incidents in short succession. Recent examples:
a) South Korea hit by a succession of typhoons: https://bit.ly/33kW7Nt

b) In the US: flooding, drought and a derecho storm in Iowa https://bit.ly/2V80pn0
c) in the UK - Farmers have experienced 'pretty much every weather extreme possible' over the past 12 months https://bit.ly/2VdBEps
d) some Australian vineyards have faced "frost, flood, insect attack, bushfire & one of the worst droughts on record— all in the last 18 months"

e) Central America hit by back-to-back hurricanes after being 'pounded by year-after-year of crop-destroying droughts' thoroughly devastating food-security. Throw COVID in, and:
