Note that the original Paris 1.5°C target referred to keeping under 1.5°C for the entire period from 2015 to 2100, requiring sustained action between 2020 and 2030 to have any hope of setting that trajectory. We are so, so far away from that goal. The maximum by 2100 is going to be at least 2.2°C for sure, but 2.5°C and beyond are more likely.
