Carbon dioxide forcing alone insufficient to explain Palaeocene-Eocene Thermal Maximum warming
Abstract
About 55 million years ago global surface temperatures increased by 5-9 ∘C within a few thousand years, following a pulse of carbon released to the atmosphere. Analysis of existing data with a carbon cycle model indicates that this carbon pulse was too small to cause the full amount of warming at accepted values for climate sensitivity.
