The Great Acceleration is the dramatic, continuous and roughly simultaneous surge across a large range of measures of human activity, first recorded in the mid-20th century and continuing into the early 21st century.[1][2] Within the concept of the proposed epoch of the Anthropocene, these measures are specifically those of humanity's impact on Earth's geology and its ecosystems. Within the Anthropocene epoch, the Great Acceleration can be variously classified as its only age to date, one of its many ages (depending on the epoch's proposed start date), or its defining feature that is thus not an age, as well as other classifications.[3][4]
Environmental historianJ. R. McNeill has argued that the Great Acceleration is idiosyncratic of the current age and is set to halt in the near future; that it has never happened before and will never happen again.[5] However, climate change scientist and chemist Will Steffen's team have found evidence to be inconclusive to either confirm or refute such a claim.
Related to Great Acceleration is the concept of accelerating change. While not explicitly commenting on whether the Great Acceleration as a whole is set to continue into the near future, the common implication is that the particular trend of accelerating progress will not cease until technological singularity is achieved, at which point technological growth becomes uncontrollable and irreversible, resulting in unfathomable changes to the Earth and possibly even the universe itself.[5] Therefore, while adherents of the theory of accelerating change do not comment on the short-term fate of the Great Acceleration, they do hold that its eventual fate is continuation, which also contradicts McNeill's conclusions.
The International Geosphere-Biosphere Programme (IGBP) has divided and analyzed data from years 1750 to 2010 into two broad categories, each with 12 subcategories.[8] The first category of socioeconomic trend data illustrates the impact on the second, the earth system trend data.
