Adventures in estimating climate sensitivity
Climate sensitivity (usually defined as the equilibrium warming in response to doubled CO2) is one of the most important and uncertain parameters in climate science. I will review the history of estimates of the quantity and explain why internal variability makes it hard to estimate this quantity from observations. I will then show a new estimate that uses observations of internal variability of the climate system and which is less impacted by internal variability. Our analysis yields and estimate that ECS is likely 2.4-4.6 K.
