Here are two talks that Nobel laureate and inventor of the PCR test Kary Mullis gave in 2010, which clarify his belief that the supposed science underpinning the climate change narrative is "trash." Mullis, who had no qualms about speaking his mind, notes in the talks that humanity has had a negligible impact on Earth's surface and atmospheric temperatures, and that real, experimental evidence (as opposed to computer modeling) has shown that, despite an increase in atmospheric CO2, Earth has not been warming with any significance.
