In a recent comment, a reader posted a graphic in which CO2 and sea-level rise appear to be correlated throughout the last 700,000 years.
Why Don’t Global Surface Temperature Trends Match Atmospheric CO2 Increases?
Question submitted to Scripps Oceanography science magazine explorations now by Ruben M., Watsonville, Calif. Great question Ruben! The surface temperature we experience every day is not expected to perfectly track CO2 because CO2 isn’t the only factor driving climate change. Still, it is quite an important factor, and the overall rise in temperature does roughly follow the overall rise in CO2. … Read More
