Analysis of phytoplankton fossil carbon isotope fractions indicates substantial atmospheric CO2 decline in the last 15M years, suggesting a climate sensitivity far higher than previous IPCC models

Analysis of Pacific Ocean sediments shows doubling atmospheric CO2 might raise Earth’s temperature by 7 to 14 degrees, exceeding IPCC predictions

Continuous sterane and phytane δ13C record reveals a substantial pCO2 decline since the mid-Miocene, suggesting climate sensitivity far higher than previous IPCC models
