Debunking the 'Heat Only Rises' Claim
AAP FactCheck examines the claim that atmospheric carbon dioxide cannot warm the earth's surface because "heat only goes up".
Experts assert that while warm air rises, this does not preclude atmospheric carbon dioxide from warming the earth's surface.
Having reached the air, CO2 no longer has any possible heating effect. Have you forgotten what we learned at school, that heat goes UP??
However, scientists explain that heat is transferred in all directions, including downwards, through radiation, which is how CO2 warms the planet.
This process can be observed using scientific instruments, contradicting the claim that any warming from CO2 would only occur "in the sky".
AAP FactCheck concludes that the claim defies climate science, as CO2 transfers heat in all directions.
