Study: Temperature Changes Have Determined CO2 Changes Since The Phanerozoic
by Kenneth Richard  1 day ago 
 

Popular claims that carbon dioxide (CO2) changes drive temperature changes currently or throughout the distant past are “based on imagination and climate models full of assumptions.” [emphasis, links added]

A comprehensive new study details a stochastic assessment determination of the sequencing of CO2 variations versus temperature variations since the 1950s, over the last 2,000 years (the Common Era), and throughout the last 541 million years.


The robust conclusion is that the causality direction – with the understanding that causes lead and effects lag – clearly shows the temperature changes lead and CO2 changes lag on yearly, decadal, and centennial/millennial scales.

In other words, “the reverse causality direction [CO2]→T should be excluded.”

Heat the ocean, heat your beer...either way, the solubility of CO2 decreases, and it comes out of solution. Atmospheric levels of CO2 have always been a trailing indicator, it is only in fantasy that future events get credit for what is happening now.

Temperature and carbon dioxide data from the Vostok ice-core [50-52]. Note that temperature rises before carbon dioxide, not vice versa. This figure shows compelling evidence that temperature rise results in a subsequent increase in atmospheric carbon dioxide content, in striking contradiction to the IPCC model-driven assumption that CO 2 causes global temperature increases. The rise or fall of CO 2 follows the increase or decline of Earth's variable heat, absorbed from above and produced from below
