Really?Large portions of India, Pakistan, Egypt, West Africa, Australia and the midwestern USA.
A 5C rise will result in days with wet bulb temperatures of over 35C, which is lethal to any human or large animal that can't get into an air conditioned space. At that combination of temperature and humidity, a person resting in the shade next to a fan still overheats and dies. Conditions like that would only be seen on the hottest days, but it would only take one such day to kill everyone.
And even if you can AC the people, the crops still die. For example, corn dies after a few hours at 110F. And all the livestock dies, and much of the wildlife.
Yet life on the planet was greatest when it was even warmer than a 5C rise (which even cultists are not predicting). Animals that weighed hundreds of tons were walking around enjoying themselves.
Or are you going to now deny the fossil record?
BTW- corn won't germinate unless the ground is 55F, and will happily grow at 110 if provided water.
