The name Anthropocene is derived from Greek and means the “recent age of man.” Although American biologist Eugene Stoermer coined the term in the late 1980s, Dutch chemist and Nobelist Paul Crutzen is largely credited with bringing public attention to it at a conference in 2000 as well as in a newsletter printed the same year.
In 2008 British geologist Jan Zalasiewicz and his colleagues put forth the first proposal to adopt the Anthropocene Epoch as a formal geological interval.
Many preexisting carbonate formations will dissolve in response to increases in ocean acidity, leaving a signature of striking dark layers of carbonate-depleted rock. By far the most significant evidence of the Anthropocene in rock strata will be caused by a dramatic increase in extinctions occurring during this period.
The Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth's history when human activity started to have a significant impact on the planet's climate and ecosystems.
Anthropocene. a new geological epoch following the Holocene (12,000 years of stable climate). Defined as the current geological age, viewed as the period during which human activity has been the dominant influence on climate and the environment. You just studied 39 terms!
A growing group of scientists argue that the Anthropocene Epoch should follow the Holocene Epoch (11,700 years ago to the present) and begin in the year 1950. The name Anthropocene is derived from Greek and means the “recent age of man.”
The Anthropocene is sometimes used to simply describe the time during which humans have had a substantial impact on our planet. Whether or not we are in a new geological age, we are part of a complex, global system and the evidence of our impact on it has become clear.
Also known as the Holocene, this is the human era on earth. You just studied 14 terms!
The anthropocene is mainly characterised by three factors: the technological progress that sped up after the First Industrial Revolution, the explosive growth in population thanks to improvements in food, health and hygiene, and the multiplication of production and consumption.

In these essays, the Anthropocene is defined as the era in which humans decided that humanity was the most important influence on the world. It is a circuitous definition, the humor and despair of which is not lost on Green (Turtles All the Way Down).
Although the biologist Eugene F. Stoermer is often credited with coining the term anthropocene, it was in informal use in the mid-1970s.
Geologists have detected a worldwide marker laid in the 1950s, which could signal the start of the Anthropocene. During that period, radioactive particles released from nuclear weapons deposited a vivid marker in sediments around the world.
The Anthropocene is a new, present day epoch, in which scientists say we have significantly altered the Earth through human activity. These changes include global warming, habitat loss, changes in the chemical composition of the atmosphere, oceans and soil, and animal extinctions.
Consequences of the Anthropocene These human actions cause, among other consequences, changes in the water cycle, imbalances and destructions in the marine and terrestrial ecosystems, the increase of extreme meteorological phenomena, the acidification of the oceans or the disappearance of the forests.

Anthropocene Epoch, unofficial interval of geologic time, making up the third worldwide division of the Quaternary Period (2.6 million years ago to the present), characterized as the time in which the collective activities of human beings ( Homo sapiens) began to substantially alter Earth’s surface, atmosphere, oceans, ...
Throughout Earth’s history, periods of upheaval characterized by mass extinctions, changes in sea level and ocean chemistry, and relatively rapid changes in prevailing climate patterns are captured in the layers of rock. Often these periods mark the end of one interval and the beginning of another.
Formal geologic time begins at the start of the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day. Modern geologic time scales additionally often include the Hadean Eon, which is…. Quaternary.
