It’s already making things hard. Unless you live in a cave (and even if you do, quite probably, IDK) you’ll have noticed an increase in the frequency of what’s euphemistically called “extreme weather events”. These things are bad for us, but even worse for crops, and they’re going to keep on getting worse.
The world has lost /is losing a lot of food this past year alone. Saw an article that Georgia (US) lost 90% of it’s peaches this season, folks/farms from the Midwest and Canada either couldn’t plant at all due to lack of rain or what was planted has died already.
The dam that was blown up in Ukraine ruined a huge area of farming that has global significance as they exported a lot of grains and oil seeds.
Spain is facing over 60% crop failures and the third year without honey.
Cotton crops from Texas and Spain also at a huge loss.
I am sure there’s more, this is just off the top of my head. It’ll take a little bit for it all to show up, but we are definitely going to be feeling the effects of this by next year I’m sure.
Well, it highly depends on how hard we try to stop climate change.
If you want a serious answer, read the IPCC report.
“The apocalypse is not something which is coming. The apocalypse has arrived in major portions of the planet and it’s only because we live within a bubble of incredible privilege and social insulation that we still have the luxury of anticipating the apocalypse.” by Terence McKenna

I mean, eventually, a runaway greenhouse effect would be the end of life on the planet.
End of most life. We are already in the sixth mass extinction event, the Holocene extinction, which is characterized by an extinction rate that is 100 to 1000 times higher than the normal background extinction rate and is also 10 to 100 times higher than the extinction rate of any prior major extinction event in the history of this planet. (Source) It is, however, unlikely that all life will cease to exist since there will always remain habitable zones on the planet. A true runaway greenhouse effect like the one that likely happened to Venus is (very very probably) not possible, because there is literally not enough CO2 on this planet to push Earth into complete inhabitability (Source) It will happen to the Earth naturally in about a billion years though since the sun will have become ten percent brighter by then, which will first turn the oceans into water vapor (accelerating warming via runaway greenhouse effect) and finally turn the entire planet into one big desert with surface temperatures of over 900 degrees Celsius.
