Scientists Document No Clear Warming Role For CO2 During The Last Deglaciation – Or The Last 10,000 Years

By Kenneth Richard on 4. April 2019

A new paper indicates the rise in CO2 concentration occurred well after the Northern Hemisphere’s ocean circulation changes drove the abrupt warming (~11,700 years ago) that ended the last ice age – a lag that effectively leaves no causal role for CO2 during deglaciation.

Ice core evidence from Antarctica also affirms no causal link for CO2 during deglaciation.

The Holocene record itself also contradicts the narrative that says CO2 increases drive climate warming. For the last ~10,000 years, ocean temperatures, surface temperatures, and sea levels fell as CO2 concentrations rose.

When the oceans warmed, they released the less soluble CO2 into the atmosphere. Anyone who has ever noticed a warming carbonated beverage goes 'flat' has seen this. CO2 is a trailing indicator, not a forcing component.
