# Zeke Hausfather Back to [[Topics/Climate Change Science and Policy Debate/Climate Change Science and Policy Debate|Climate Change Science and Policy Debate]] · [[Topics/Climate Change Science and Policy Debate/Research and Evidence|Research and Evidence]] **Role:** Climate scientist (Berkeley Earth; Stripe); co-author of the 2020 Nature comment calling RCP8.5 a misleading 'business as usual'. - Research scientist at Berkeley Earth and climate research lead at Stripe; writes for Carbon Brief and *The Climate Brink* ⚠️ (roles from memory). - **Hausfather & Peters 2020**, "Emissions – the 'business as usual' story is misleading", *Nature* 577:618 ([doi](https://doi.org/10.1038/d41586-020-00177-3)). It argued that RCP8.5 / SSP5-8.5 had become increasingly implausible as a no-policy baseline, and that ~3°C was a more likely current-policy outcome. - That paper is the scientific basis for the "implausible" language Clack quotes. Hausfather is clear that it does **not** mean warming is harmless. - He has also written on the Berkeley Earth temperature record, which independently confirms NASA/NOAA warming.
