WebDec 5, 2024 · When broadly viewing the paleoclimate record, one clear trend emerges: when the concentration of carbon dioxide in the atmosphere increases, temperature increases along with it—and vice versa. These values may rise and fall over 100,000 year periods, but they do so at similar rates. WebFeb 14, 2024 · The CO2 warming effect is necessary to explain both how weak orbital forcing can get us out of an ice age and also how an orbital forcing that affects only southern areas can spread through the globe. The paleo record also enables us to compare Co2 forcing with temperature change to calculate climate sensitivity.
