CO2 levels affect the planet’s climate, the more CO2 in the atmosphere, the hotter the planet becomes. No studies I could find imply that CO2 follows temperature. The only puzzle scientists had in whether CO2 directly effected climate change was because of an ice age that seemed to coincide with high CO2 levels. But newer studies have showed that the ice age occurred 10 million years earlier than previously thought, during low CO2 levels in the atmosphere. Even with normal fluctuation in CO2, today’s levels are higher than ever before, about 30% more. And remember that CO2 is not the only greenhouse gas, methane, though not as plentiful as CO2, is 120% higher than ever, and is 20 times more effective at trapping heat than CO2, resulting in temperature increase, and consequent sea level rise.
CO2 levels do fluctuate naturally, however human activity has caused the levels to rise to a much higher level than ever experienced before. What Al Gore was tryng to prove in this chart was that CO2 levels affected the temperature, not the other way around.
There is no question that CO2 affects global temperature, and the idea is certainly nothing new. The idea that the Earth’s atmosphere traps heat was first postulated by Joseph Fourier in the 1820’s, and the idea that carbon emissions by humans woud warm the planet was put forward by Svante Arrhenius around the turn of the 20th century. It’s basic physics.
