Abstract

There has been recent debate over stratigraphic markers used to demarcate the Anthropocene from the Holocene Epoch. However, many of the proposed markers are found only in limited areas of the world or do not reflect human impacts on the environment. Here we show that spheroidal carbonaceous particles (SCPs), a distinct form of black carbon produced from burning fossil fuels in energy production and heavy industry, provide unambiguous stratigraphic markers of the human activities that have rapidly changed planet Earth over the last century. SCPs are found in terrestrial and marine sediments or ice cores in every continent, including remote areas such as the high Arctic and Antarctica. The rapid increase in SCPs mostly occurs in the mid-twentieth century and is contemporaneous with the ‘Great Acceleration’. It therefore reflects the intensification of fossil fuel usage and can be traced across the globe. We integrate global records of SCPs and propose that the global rapid increase in SCPs in sedimentary records can be used to inform a Global Standard Stratigraphic Age for the Anthropocene. A high-resolution SCP sequence from a lake or peatland may provide the much-needed ‘Golden Spike’ (Global Boundary Stratotype Section and Point).

  • Spherical carbonaceous particles show near-synchronous global increase around 1950 C.E., with peak signatures from the 1960s-1990s.

    “SCPs, first recorded in various sites in the UK from 1830-1860 C.E., show near-synchronous global increase around 1950 C.E., with peak signatures from the 1960's-1990's ( 32, 33 ; Fig. 2B).”

    From The Anthropocene is functionally and stratigraphically distinct from the Holocene (2016) · cites this paper as [33]

    The paper’s main text states that British SCP records commonly begin in AD 1830–1860 and that their rapid increase occurred around AD 1950–1960s. It also describes the rapid increase as a mid-twentieth-century global signature. The passage on peak concentration says its timing varies spatially, but does not establish peaks specifically in the 1960s–1990s. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
