The analysis

The retrieved papers provide robust empirical evidence that human activities leave detectable, long-lasting physical structures, chemical residues, and sedimentary anomalies in geological archives such as ice cores, lake and marine sediments, and the subsurface. These findings directly support the claim that geological records contain detectable anthropogenic signatures.
