evidence: The claim appeared in multiple outlets, including Watts Up With That, the Daily Signal, and a Facebook post published by I Love Carbon Dioxide in April 2020. While human additions of CO2 are small relative to natural processes, atmospheric CO2 measurements are currently much higher than pre-industrialization CO2 levels and not within the "margin of error of current estimates," as described by the reviewers below[1,2]. The ocean does release CO2, but scientific evidence demonstrates that oceans have absorbed approximately 23% of global anthropogenic CO2 emissions since the Industrial Revolution, thus serving as a net sink rather than a source of CO2[3,4]. This claim also fails to recognize that human-induced CO2 emissions have caused imbalances in the global carbon cycle. [...] Secondly, the claim that the increase results as "the Planet emerges from the last ice age" is wrong for multiple reasons. Firstly, ice-core atmospheric CO2 records suggest that such a strong increase (from 280ppm to 412 ppm) is unprecedented in the last 800,000 years. Secondly, these records also show that the speed at which atmospheric CO2 increases is unprecedented in the ice-core record history.
