evidence: A recent study conducted by scientists from Oregon State University and the University of St Andrews has revealed that the rate of atmospheric carbon dioxide (CO2) increase is currently ten times faster than at any point in the past 50,000 years. [...] The study, published Monday in the Proceedings of the National Academy of Sciences (PNAS), demonstrates that the rate of CO2 increase today is ten times higher than the previous natural rises observed in history and "largely driven by human emissions." [...] During the last ice age, there were instances where CO2 levels appeared to rise significantly higher than the average. However, previous measurements lacked the precision to reveal the full extent of these rapid changes. The recent study addressed this limitation by conducting detailed measurements during those periods, uncovering an unprecedented rate of CO2 increase. While natural rises in the past took about 7,000 years to achieve a magnitude similar to the current increase, today’s levels are surpassed within a mere five to six years.
