It's not so simple. 1.5C was decided on after assuming 2C would be fine after (warranted) political pressure from more at risk countries. What are the risks is really more about climate sensitivity than a specific temperature, think of it as how much can change given a warming of X degrees. Recently there is growing scientific evidence that dangers we thought were only possible at high temp scenarios, say 3-4C, are possible at 2C or might even be underway. Meaning that the climate is more sensitive than had been projected. This means that not only according to the study linked above are we closer 1.5C + 2C, but we also have more to fear from passing those temps because more can go wrong at lower levels of warming. Every tenth of a degree matters and we should stop obsessing over 1.5C or 2C and work on mitigating as much as possible and preparing for whats coming and slow emissions and pollution as much as possible
