Simple: reflecting sunlight does nothing to remove CO2 from the atmosphere, or to reduce the amount going into the atmosphere. The CO2 is the problem, not the temperature. The temperature is a measure of the CO2 problem. Force the temperature, and it ceases to become an accurate measure.

As CO2 continues to build up, ocean pH decreases, reflecting increasing acidification. As pH decreases, the base of the ocean food chain begins to collapse. When the ocean food chain collapses, the main protein source for much of humanity vanishes. Global war follows, and civilization collapse. Slightly lower temperature is unnoticed.

Higher temperatures is the FIRST and WORST problem. Mitigating the damage already done would be very nice.

We still need the energy transition though.

Higher temperature is unpleasant. Famine kills.

Higher temperatures lead to famine, and also directly to death, and ecosystem collapse.

So all the experts who talk about the 2 degree celsius goal did set the goal on the wrong measure? Please be more convincing than just restating your previous hypothesis.

As far as I understand the situation, the increased average temperature is the problem. Not because every day would be exactly n degrees warmer/hotter, but because it leads to way more variance in the atmosphere, i.e. storms, hot and cold extreme wheather etc. The CO2 itself might also induce problems. But they do not dominate the situation.

Failing to control CO2 leads inexorably to global collapse of civilization, regardless of temperature.

Civilization would also collapse as a consequence of extreme temperature.

Temperature increase is easier to limit, but redirecting resources to limiting temperature accelerates CO2 increase, thus collapse from that.

Directing resources to reducing CO2 also limits temperature rise.

Extreme fever can kill the patient. Plunging the patient in ice water cuts fever, but fails to save the patient. Antibiotics may take longer to reduce fever, but offers the possibility of saving the patient.

But betting everything on one horse, company, or intervention is rarely a good strategy. I think Nicolas Nassim Taleb makes compelling arguments in his books, starting from the Black Swan.
