Yet another region of the globe has failed to cooperate with anthropogenic \u201cglobal\u201d warming narrative.<\/strong><\/h4>\n\n\n\n

According to climate models constructed on the presumption that CO2 concentration changes are the driver of climate, Central Africa should have been warming in recent centuries in tandem with the rise of atmospheric CO2.<\/p>\n\n\n\n

However, scientists (M\u00e9not et al., 2025<\/a><\/strong>) using brGDGT (branched glycerol dialkyl glycerol tetraether) proxies to reconstruct paleo temperature trends have determined the Cameroon region test site is likely colder today than any other time in the last 7000 years.<\/p>\n\n\n\n

Mean annual air temperatures (MAAT) are 22\u00b0C at the study site today. About 7000 years ago, when CO2 concentrations were ~265 ppm, MAATs were 24.5 to 25.5\u00b0C, or at least 2.5\u00b0C warmer today.<\/p>\n\n\n\n

As CO2 levels rose throughout the Mid- to Late-Holocene, temperatures continued to decline. This negatively correlated trend is the opposite of model predictions.<\/p>\n\n\n\n

\u201cA 2.5\u00b0C temperature drop in 7000 years exceeds current model predictions.\u201d<\/em><\/p>\n\n\n\n
