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 crops

3. Reduced chill hours required for many plants to bloom normally in the spring

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):

5. Severe crop damage from wind storms - in this case, ~$7.5 Billion in damage from a single storm:

6. Also wind (& heat) related - increasing prevalence of ‘furnace winds’. 

-these are as bad as they sound - they can damage crops in a few short hours:

7.  And another phenomenon that is an intensification of the existing- “flash droughts”

New secondary factors include:

1. Hoarding - even at the national/international scale - something we have disturbingly see with #COVIDー19.

Don't expect your neighbours and allies to come to the rescue:

2. Farmer mental health taking a toll - in the U.S. (bit.ly/3fUDrtn) and internationally, in extreme cases leading to suicide (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: bit.ly/33kW7Nt

b) In the US: flooding, drought and a derecho storm in Iowa

c) in the UK - Farmers have experienced 'pretty much every weather extreme possible' over the past 12 months

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:

“This is the worst year we have ever lived”
