Someone I know who worked in the climate sciences once put it so clearly to me. An increase of 1 degree is global, and with 70% of the world being ocean that raises much slower, the temperature rise over land is effectively doubled. So 1c degree is 2c. A 2c world is 4c. That when CO2 was 100 point less than the 280ppm baseline we had an ice age with glaciers down to the 40th(ish) parallels in the Northern Hemisphere. We have now pushed it 150 above the baseline in effectively 150 years and fast accelerating. What seems like something trivial, is actually forcing on an unbelievable scale. Also a fun visualization, roughly speaking 1 part per million in water vapor is what a cloud looks like. If CO2 had the same visual properties as water, it would be pitch black on the ground. People keep looking to the past for answers, and yes it does provide valuable context. But what we are doing now has never happened on this planet, we are blindly rushing into a future that is beyond comprehension. Some things will go worse than expected, some thing will go a lot better, but nobody really knows just yet. Also to the last line "I am glad that I live far away from the effects", alas, this isn't like empires of the past that are geographically limited. Those that can collapse but there is still plenty of untouched lands and civilizations. We now live in a global system, a six continent supply chain. We will all be impacted.
