Reply to comment by Electrolight in Changes in Earth’s orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change by giuliomagnifico
It has to do with timescales.
As an example, consider the world's population. It took only 70 years for the world to triple it's population (and some countries have seen a 6-fold increase in their population in that time).
There is no ethical way of exactly reversing that and reducing the population by a factor of 3 in 70 years. It will take at least 200, if not longer.
To get our carbon levels down to 1970 levels will take us much longer than 50 years. In the meantime the world will continue heating and secondary effects will kick in.

Reply to comment by dontcareitsonlyreddi in Climate change is extending the lifetime of space debris. A new study found that the density of the thermosphere will decrease by 30-35% at an altitude of 250 miles over the next few decades. That loss of drag would increase the lifetime of space debris in LEO by 30% compared to 2000. by clayt6

Reply to comment by Vainpaix in TIL about Saint Josaphat (aka Būdhasaf), a legendary Christian saint whose life is based on Gautama Buddha, the founder of Buddhism. His life story tells of how Josaphat, a son of an Indian kind that persecuted the Christian Church in his kingdom, converted to Christianity. by kweenllama
Christians were by no means a specifically persecuted minority. While it did happen, it was sporadic:

This was definitely not of the order of requiring them to withdraw into caves.
