About this episode
How reliable are the measurements behind climate claims? In this episode of Sanity Check, David R. Legates examines the data systems used to estimate Earth’s energy imbalance—particularly ocean temperature measurements from Argo floats. While widely treated as authoritative, these measurements rely on sparse sampling, interpolation, and assumptions that introduce significant uncertainty.
The result: the margin of error may exceed the signal itself, raising serious questions about the precision of current climate estimates and the confidence placed in them.
