While such a scenario is certainly possible, it's not something that can be achieved by humanity by solely leverage on its current capacities to transform earth environment. See for example https://www.sciencetimes.com/articles/47070/20231113/earth-s-oceans-boil-away-what-factors-make-planet-lose.htm https://www.sciencetimes.com/articles/47070/20231113/earth-s... So, to answer your question, in the part where humanity can certainly change the world to its own detrimental, but is currently not able to really put it in a state where absolutely no life form is conceivable anymore, and that even putting it a state where some hunters gatherers would not be able to survive is not a 100% garantie outcome of current trends. though I would rather consider the current trend rather awful if you ask.
