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 (www.nature.com)

When we again weigh each sensitivity by the percent-area for the Earth, our global average ECS is 7.2 °C per doubling of CO2, much higher than the most recent IPCC estimates of 2.3 to 4.5 °C and consistent with some of the latest state-of-the-art models which suggest ca. 5.2 °C

2.3c means crop failures and food shortages globally. 5.2c means the end of our civilisation. 7.2c means the end of our species.

Was just reading the abstract to see how fucked humanity is, and this one says we are super fucked.
