anthropocene
The term ‘Anthropocene’ was coined in recognition that human activities have ended the relatively stable environment of the Holocene epoch. However, its widespread adoption across the humanities, arts and sciences has led to diverse and sometimes incompatible definitions. In this Perspective, we argue for a stabilized definition of the Anthropocene epoch to help address contemporary environmental challenges, and explore various applications of the Anthropocene across disciplines. The Anthropocene epoch, with a proposed start point in 1952, underscores that human-driven global-scale environmental disruption differs from earlier human impacts of the Holocene, which did not cause such profound destabilization. This clear distinction enables quantitative and qualitative comparisons between the Holocene and Anthropocene epochs, as already utilized, for instance, within the planetary boundaries framework. As the Anthropocene Earth system transformation is systemic, political responses also need be systemic, rather
A new study finds two persistent mental shortcuts—not ignorance—are why people keep overrating recycling and underrating flying less.
While the term “Anthropocene” is well established across scientific disciplines and social spheres, interpretations are diverse. Taking account of the 2024 rejection by a geological commission to accept the Anthropocene as a geological epoch and the related scientific debate, here we offer a future-oriented perspective from the viewpoint of Earth system science. We describe different pathways in the Anthropocene up to the year 3,000, systematically characterizing them according to impacts and causes. We discuss the enormous global consequences of anthropogenic pressures on the Earth system and quantify the corresponding long-term commitment to change. Regarding the causes, we conservatively explore best-case and middle-of-the road emission scenarios, in combination with climate sensitivities drawn from within the IPCC likely range. We also discuss implications for Earth system resilience that could result in what we call worst case scenarios for Anthropocene outcomes. We conclude that, beyond the slow pace of
How Cynicism Became the New Psychological Performance
As civilization advanced, humans developed tools that allowed us to shield ourselves from the natural cycles that once defined our lives. Fire helped us escape the cold. Irrigation let us shape landscapes around our needs. Walls and weapons kept predators at bay. Over time, these inventions accumulated into infrastructure, then ideology. The more protected we became, the more separated we felt...
Scientists have been debating the start of the Anthropocene Epoch for 15 years. I was part of those discussions, and I agree with the vote rejecting it.
This volume addresses political action in Anthropocene and tension between the Promethean project of modernity and post-Promethean approach.
This Handbook explains the complexity of the concept of the Anthropocene, scientific and a political concept and also an ideological concept.
Plutonium spike in Canadian lake sediments marks dawn of new epoch in which humanity dominates planet
Presently, there is a scientific debate about which epoch we are in. The discussion centers around the Holocene vs Anthropocene question.
The Anthropocene defines Earth's most recent geologic time period as being human-influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric and other earth system processes are now altered by humans. The word combines the root "anthropo", meaning "human" with the root "-cene", the standard suffix for "epoch" in geologic time. The Anthropocene is distinguished as a new period either after or within the Holocene, the current epoch, which began approximately 10,000 years ago (about 8000 BC) with the end of the last glacial period.
A major concern for the world’s ecosystems is the possibility of collapse, where landscapes and the societies they support change abruptly. Accelerating stress levels, increasing frequencies of extreme events and strengthening intersystem connections suggest that conventional modelling approaches based on incremental changes in a single stress may provide poor estimates of the impact of climate and human activities on ecosystems. We conduct xperiments on four models that simulate abrupt changes in the Chilika lagoon fshery, the Easter Island community, forest dieback and lake water quality—representing ecosystems with a range of anthropogenic interactions. Collapses occur sooner under increasing levels of primary stress but additional stresses and/or the inclusion of noise in all four models bring the collapses substantially closer to today by ~38–81%. We discuss the implications for further research and the need for humanity to be vigilant for signs that ecosystems are degrading even more rapidly than previo
Only if there is a fundamental change in the way we manage land we can reach the targets of climate-change mitigation, avert the dramatic loss of biodiversity and make the global food system sustainable.
The Anthropocene Working Group is voting on a so-called Golden Spike, a sedimentary layer somewhere on Earth that best exemplifies the global impact of humans on planet Earth. It's the last, big task in formally defining the Anthropocene, which is being proposed as a new age in geologic time.
Although interest in colonisation has grown throughout the West in recent years, it is mostly limited to historical colonialism. Little attention is paid to the ways in which we colonise the future. However, this is done with the same ruthlessness and short-sightedness with which regions around the world were invaded in earlier times. During the 50th edition of the Huizinga Lecture, David Van Reybrouck focuses on the way in which humanity is currently plundering and enslaving future generations. And further, the violence is not limited to human but affects all life on earth.
The rapid decline of Earth’s most numerous animals is a major threat to the biosphere
Humanity is now a ‘geological superpower’ and declaring a new epoch is critical to tackling its impact, scientists say
Scientists are to pick a location that sums up the current Anthropocene epoch when Homo sapiens made its mark
The specific fallout products released following a nuclear detonation depend on the characteristics of the device detonated and the nature of the detonation. Generally, these products can be organized by the following three categories, based on their mode of generation...
Résumé fr - Alain Vézina - Au cours des 11 700 dernières années, pendant lesquelles la civilisation humaine s'est développée, la Terre a vécu dans ce que les géologues appellent l'époque holocène. Aujourd'hui, la science nous dit que l'époque de l'Holocène s'est achevée sur l'échelle des temps géologiques et qu'elle a été remplacée par une nouvelle époque, plus dangereuse, l'Anthropocène, qui a débuté vers 1950. L'époque de l'Anthropocène se caractérise par une "faille anthropique" dans les cycles biologiques du système terrestre, marquant un changement de réalité dans lequel les activités humaines sont désormais la principale force géologique ayant un impact sur la terre dans son ensemble, générant en même temps une crise existentielle pour la population mondiale. Qu'est-ce qui a provoqué ce changement massif dans l'histoire de la Terre ? Dans cette étude exhaustive, John Bellamy Foster nous apprend qu'un système mondialisé d'accumulation du capital a incité l'humanité à faire son propre ni
