If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.Will humans go extinct in 2050?
By 2050, human systems could reach a "point of no return" in which "the prospect of a largely uninhabitable Earth leads to the breakdown of nations and the international order."Can humans escape extinction?

Perhaps we will have longer arms and legs. In a colder, Ice-Age type climate, could we even become even chubbier, with insulating body hair, like our Neanderthal relatives? We don't know, but, certainly, human genetic variation is increasing.Will dogs become extinct?
