Spheroidal Carbonaceous Particles
Spheroidal carbonaceous particles (SCPs) is a form of black carbon produced from burning fossil fuels in energy production and heavy industry that is thought to provide stratigraphic markers of the human activities that have changed Earth since the 20th century and thus the anthropocene with the unprecedented rise in the industrial carbon intensity. Humans have modified the carbon cycle, leaving footprints of carbon in the air and the outer earth crust. SCPs – just as other pollution markers of modern human industrial activity like plutonium or microplastics, are found in terrestrial and marine sediments or ice cores in every continent and they have turned up there isochronous A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term ''isochronous'' is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval ( ...ly since the 1950s.

Black Carbon
Black carbon (BC) is the light-absorbing refractory form of Chemical_element, elemental carbon remaining after pyrolysis (e.g., charcoal) or produced by incomplete combustion (e.g., soot). Tihomir Novakov originated the term black carbon in the 1970s, after identifying black carbon as fine Particulates, particulate matter (PM ≤ 2.5 μm aerodynamic diameter) in aerosols. Aerosol black carbon occurs in several linked forms. Formed through the incomplete combustion of fossil fuels, biofuel, and biomass, black carbon is one of the main types of soot particle in both human impact on the environment, anthropogenic and naturally occurring soot. As soot, black carbon causes disease and premature death. Because of these human health impacts, many countries have worked to reduce their emissions. In climatology, aerosol black carbon is a climate forcing agent contributing to Climate change, global warming. Black carbon warms the Earth by absorbing sunlight and heating the atmosp ...
