Earth's recent climate spiral.

[The Grand Nudger]

Global food production will be disrupted

CO2 is a fertilizer and plants benefit from warmer wetter climate.

Profoundly wrong.  Firstly, co2 isn't a fertilizer...but supposing that it was, most people know that too much of any given fertilizer is not, in fact, good for plants.  Further, in the standard model, food production actually depends on moderate temperatures and dry soil conditions.  Warm and wet is a recipe for mildew, mold, fungus, soil parasites, anaerobic conditions and bacteria, insects, and mechanical failures...and, all of this, is before we talk about damage to critical on and off farm infrastructure as well as standing crop and the markets in which they sell from the events that would follow a warmer and wetter climate.  50 years ago it was decided that if you couldn't irrigate it, you shouldn't grow it.  That became the rule.  50 years from now it will be decided that if you can't cover it, don't grow it.  

In the coming decades, even if we were to stall agw right where it is now, conventional ag will need to relocate while making massive investments in climate controlled growing facilities, where the leading edge of ag is right now.  This is great for small producers like me who aren't tied to huge pieces of largely unsellable real estate and who came into the sector with hydro and polypro- but it's not great for markets or the food supply.  Doesn't really matter if it's great for "plants". Kudzu is a plant.

the backdrop to this will be more frequent and more intense weather events.

Wikipedia says that high hurricane frequency is caused by cleaner air.

Hurricanes are caused by the convection of warm moist air.  

Now, IDK what nuts you listen to, but if you're listening to one set of nuts saying it will be the end of the world

In my experience almost all climate alarmists claim that it will be the end of the world.

They might have folks like you in mind when they say as much.  Food for thought.
