if the climate changes in ways that damage agricultural yields.
There's no evidence whatsoever that the climate is changing in a way that would damage our yields on a global scale. There's a lot of quite convincing evidence on the contrary, feel free to google for biomass increase over the last couple decades.
Apart from evidence, I urge everyone to use basic logic, for a start. CO2 + heat = greenhouse. It's a fricking greenhouse effect, is it not? The crops grow best fricking where? What do you build to increase your yield from a square mile?
I didn't. My first computer was a 8-bit machine.
My first computer didn't even have 8-bits. It had 2, but you couldn't use both at the same time. You had to go up 7 floors to get the other bit and then swap them out.
You were lucky to get that, mine had only one bit and it could only hold zero in it!
