Holocene vs. Anthropocene

27 0
24.04.2024

Recently, the International Union of Geological Sciences (IUGS) refused to recognise the current geological time as the Anthropocene (Human) Epoch because adding an Anthropocene Epoch ~ and terminating the Holocene Epoch ~ was not supported by geological standards used to define epochs. This decision was unpalatable to many scientists and laymen, because undeniably humans are now the dominant geologic force on the earth’s surface.

However, the IUGS did recognise that the term Anthropocene described a distinct and definite time. The IUGS said: “Despite its rejection as a formal unit of the geologic timescale, the Anthropocene will remain … an invaluable descriptor of human impact on the Earth system.” This alternative view is more persuasive because human activities of digging mines, construction of dams, expansion of cities and clearing of forests for agriculture and urbanisation ~ will all be visible in the geological record. Also, associated phenomena of pollution, global warming, climate change, and habitat destruction, leading to mass extinction of plant and animal species are definitely an ‘event’ ~ an informal term geologists use for profound changes to the earth system.

Scientific quibbles aside, it cannot be denied that human activities have made planet earth inhospitable for humans. Six leading international datasets used for monitoring global temperatures, consolidated by World Meteorological Organization (WMO) show that the annual average global temperature was 1.45 ± 0.12 °C above pre-industrial levels (1850-1900) in 2023. Global temperatures in every month between June and December set new monthly records, with July and August being the two hottest months in recorded history. This trend has continued; global temperatures rose to 1.66 °C above average during January 2024, making it the hottest January on record. Recently, a number of extreme climate events were noticed:

* Temperatures are rising worldwide, because increasing greenhouse gas emissions trap more heat in the atmosphere. According to the World Meteorological Organisation, the last eight years have been the hottest on record. After widespread heatwaves in 2022, April 2023 again saw heatwaves impacting all of Asia, including India and China. According to Scientific American, July 2023 was the hottest month in the last 120,000 years, with........
