Such an event would render swaths of the planet truly uninhabitable and much more land un-farmable. Humanity must abandon the tropics entirely. Every costal city is now 300 feet underwater. Billions die in mass migrations and wars on a scale hitherto unseen. The ecosystem of the planet is ravaged by this rapid change, being unable to evolve quickly enough to adapt. The life that remains is agriculture that directly sustains the few human survivors. Scientific progress halts entirely. The ultra-rich retreat into their enclaves while what remains of humanity regresses into Morlocks. In short, 10 degrees should be regarded as apocalyptic. It would turn back human progress by millennia, and the state of planet would not return to "normal" for several millennia more, if ever. Perhaps for a century or two some outposts in greenland cling to survival but over the longest term, it's not clear if humanity can survive such conditions. Perhaps we can adapt to this terrible "new normal" but our ancestors will tell myths about "The Earth that Was". Their children will marvel at the idea that Earth once had "wildlife". They will tell cautionary tales about their foolish and near-sighted predecessors who had inherited a garden of eden and but destroyed it to fuel their insatiable appetites.
