Overwhelming scientific evidence shows earth’s climate has always changed, and correlates with the sun, not human fossil fuel use or CO2 emissions.

Smaller variations occurred in the last 10,000 years since the end of the last ice age, with temperatures often warmer than today, long before human emis­sions
