This is like the death cults claiming The World Will End At Exactly... - and it doesn't, and the whole thing fizzles out.
1.5C will suck. 2C will suck more. Etc. But it's not like there's some magical point where it won't suck.
The thing is, there were no humans at the time and life was a bit different.
We're talking some 50 year timespan to terrible effects, that means most everyone here will be affected. They may be affected more or less. Current trajectory is on more, bordering on deadly. The time for low impact has passed, thanks to people like you dismissing actual scientists as alarmist. We've known this for 40+ years now. It's become public knowledge at least 25 years ago.
The climate system has a lot of inertia, century scale at times, once pushed too hard humanity might not be able to stop it, no matter what we do.

It's already happening, as your links show. Double-digit percentage crop loss in some areas, which has already resulted in empty supermarket shelves for some staples[0]. And food prices are already reaching record highs. It won't be long before heat bubbles hit the wrong places at the wrong times and kneecap the world's food supply.
In the meantime, the human population is still rising sharply[1], with 2 billion more mouths to feed coming before the population curve will start to level out. Things aren't looking good.

On a small note, I wasn't aware of the pasta situation. I was surprised earlier this week when there was no pasta at the local Costco, sadly that explains it.
