Climate Change: the hot planetary boundary

Either we disrupt the economic system of a gradual path to transition from fossil fuels, extreme weather disrupts us, or most likely we deal with a mix of both disruptions. We are living through many trends that simply cannot continue, and while there is competition for which trend reaching a tipping point will cause the greatest disruption over the next decade, the environment and rising CO2 levels will play a key role by 2030. While some righteous environmentalists protest for everyone to embrace austerity and simply just stop burning fossil fuels, what is required is replacement infrastructure reliant on fossil fuels. In practice we can't switch off until positive action replaces the need for fossil fuels, which is progressing too slowly in a failing effort to avoid disrupting economies and the establishment. Reality is both the extreme weather events that further motivate action and those actions themselves will cause disruption, which will both combine with the disruption from AI and the collapse of economic Ponzi schemes.

I started out wondering how much temperatures have risen so far, what is the best estimate for when will reach +1.5°C , and how bad is +1.5°C anyway. I expected that finding the first two answers would be easy, but it was not. I found the answers, and why they were not easy to find. I found that with warming at +1.0 in Paris in 2015, +1.5 logically seemed 50 years away, but in 2021 just 6 years later, we are halfway there at +1.25°C. Much changed during the Covid-19 distraction, and at this rate +1.5°C is set to be here by 2026, not the 2050 predicted at Paris.
