The trends we are facing will put the average temperature at a level only seen once during our period of dominance. By the end of the century we face a temperature last reached 1-2 million years before our ancestors stood up for the first time. As a species, this is uncharted territory and was from a time when our very early ancestors were prey, not predators. That should be sobering to consider.
