The idea that humanity, or even civilization is only 20,000 years old is hilarious at this point.Only showing the temperature change since the last ice age may be deceiving. Throughout much of Earth's geologic history, the global mean temperature was between 8°C and 15°C warmer than it is today with polar areas free of ice. These relatively warm periods were interrupted by cooler ice ages.
