I don't think you understand what that number means at all.

24K years ago New York was under 4 miles of ice, during summer. If that happened today, do you think the government of Canada and United States would survive such a schenario?How many people would be left alive in North America, 30% of the current population?

How big do you think the change in global temperature was during the last ice age? 30 degrees or 20 degrees?

It was only 6 degrees. That's all it takes.

Average yearly temperature for Hong Kong is 23 degrees, for Dubai it's 26 degrees.

3 degrees is the difference between lush tripics and a desert where you will starve because nothing grows.

A global change of 3 degrees means 12 degree change on land because 70% of the planet is an ocean and it's tempersture doesn't change

Who is seriously claiming catastrophic collapse on the 2-3 degrees increase trajectories?

Literally anyone who studied impact of changing climate on food security. And we will not see a warming of 2 degrees, we are on track for 4 - 6 degrees. The 3 degrees scenario is only projects due to fictitious 'negative emissions' from carbon capture, which will cost many times more than the current revenues of the oil industry. It's pure fantasy.
