According to the IPCC's sixth assessment report avoiding catastrophes is the unlikely possibility. Heck, just this month the Argentinian heatwave has cut their wheat and soybean harvests by almost a third. Edit: Corn, too.

  Strawman of some kind, so I'm not gonna give you an in-depth response. Across all of the possible temperature distributions that Earth's surface could have, there is some temperature distribution that is optimal for the flourishing of human civilization as we know it. The Earth has been, in the recent past, fairly close to that distribution but one of the consequences of changing the CO2 fraction of the atmosphere from around 0.025% to well over 0.04% is a change in albedo that changes Earth's surface temperature distribution towards an equilibrium that is not remotely near the optimum.

    where's the strawman? you said that a heatwave ruined crops in Argentina, and it logically follows that said heatwave is the direct result of human actions negatively affecting the planet's climate, as it's the only possible cause of such a disastrous event.

Crop yields have been on a century long increase (we produce about 5x more corn per acre than 100 years ago) in part due to CO2 fertilization, in part due to improvements in technology: https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fertilization-greening-earth/ https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fer... https://www.agry.purdue.edu/ext/corn/news/timeless/images/US_Corn_Yld_Trend.png https://www.agry.purdue.edu/ext/corn/news/timeless/images/US... https://www.nass.usda.gov/Charts_and_Maps/Field_Crops/soyyld.php https://www.nass.usda.gov/Charts_and_Maps/Field_Crops/soyyld... You'll notice from the charts year to year variability happens (droughts, heat waves, freezes, etc) but the long term trend is up and to the right.

  Thank you. And... as a note. The following statement has been down-modded in the past (this is truly an "uncomfortable truth"): If we go with no-CO2/no fossil fuel policy, we will reduce farming production, leading to famine and the likely death of (many) people. Of interest is that solar, wind, geothermal and nuclear cannot help.
