Just because there have been changes in the past does not mean that this is like all of the others. This is happening at an accelerated rate that is much higher speed than the evolution rate of plants and animals. The result will be a mass extinction of species. That has happened in the past and overall life does recover but many species are gone and things are very different afterward. No one wants to be alive during a mass extinction but they all would hope to survive. There is no guarantee that humans would survive this extinction. Even if the climate changes do not directly kill us off, it will stress our societies to a possible breaking point, with the risk of famine, war, and general societal breakdown.
