London, UK, July 2, –With the retreat of the glaciers at the end of the last major ice age began the current official geological epoch — the Holocene.

The qualitative and quantitative measure of the degree no pun intended with reference to rises in sea surface temperatures of this human impact has become increasingly sophisticated and accurate with advances in orbiting Earth observing EO technology. This technology which, as well as gathering data for well-established areas of remote sensing research, examples being meteorology and land-use monitoring, has in the time of pandemic enabled valuable data collection from measurement of reductions in atmospheric concentrations of polluting gas emissions over usually gridlocked cities, and observations on, even highly localized, population movements and social distancing regulations observance. I wrote more on this in my column here back in May this year.

Filmmakers record an atomic bomb blast in Nevada in A panel of scientists voted this week to designate a new geologic epoch — the Anthropocene — to mark the profound ways in which humans have altered the planet. That decision, by the member Anthropocene Working Group AWG , marks an important step towards formally defining a new slice of the geologic record — an idea that has generated intense debate within the scientific community over the past few years.
The panel plans to submit a formal proposal for the new epoch by to the International Commission on Stratigraphy, which oversees the official geologic time chart. Twenty-nine members of the AWG supported the Anthropocene designation and voted in favour of starting the new epoch in the mid-twentieth century, when a rapidly rising human population accelerated the pace of industrial production, the use of agricultural chemicals and other human activities.
At the same time, the first atomic-bomb blasts littered the globe with radioactive debris that became embedded in sediments and glacial ice, becoming part of the geologic record. But the vote demonstrates that the group has mostly coalesced around the geological unit.

Over the last century, humans have littered the oceans with plastic, pumped CO2 into the air and raked fertilisers across the land. Even so, the Anthropocene is far from becoming a formal piece of the geological jigsaw. While the idea has been seized enthusiastically by many in the fields of science and beyond, there are some who question the validity of naming a new epoch after humanity. Antonio Stoppani is often cited as the first person to suggest that the current geological epoch should be defined by the influence of humans.

The Anthropocene epoch
The sediments of the Holocene, both continental and marine, cover the largest area of the globe of any epoch in the geologic record, but the Holocene is unique because it is coincident with the late and post-Stone Age history of humankind. The influence of humans is of world extent and is so profound that it seems appropriate to have a special geologic name for this time. The term Holocene was proposed in and was formally submitted to the International Geological Congress at Bologna , Italy, in It was officially endorsed by the U.
Commission on Stratigraphic Nomenclature in
The Holocene record contains diverse geomorphological, biological, climatological and archaeological evidence, within sequences that are often continuous and extremely well-preserved at decadal, annual and even seasonal resolution. Yet until recently little attention had been paid to a formal subdivision of the Holocene.

New data were obtained from the radiological dating of sericite in beresites from seven ore fields in Northern Transbaykalia, and literary sources were analyzed. On the basis of these data it was concluded that the ore mineralization in the activated structures of pre-Palaeozoic folding near the Muyskiy and Charskiy projections of the basement on the Siberian platform belongs to the Late Palaeozoic epoch of tectono-magmatic activation. Within the gold-bearing metallogenetic zone of the southern pre-Palaeozoic folded frame of the Siberian platform there is a rejuvenation in the age of the gold mineralisation from Later Riphean in the west to Late Palaeozoic in the central part and Late Mesozoic in the east.

Have human beings permanently changed the planet? That seemingly simple question has sparked a new battle between geologists and environmental advocates over what to call the time period we live in. But that label is outdated, some experts say. Anthropocene has become an environmental buzzword ever since the atmospheric chemist and Nobel laureate Paul Crutzen popularized it in

The most common issues with Epoch. I don’t know if sitejabber will print this review, but I love this paper! Epoch gives a more realistic reports and I love the diversity of the paper, especially the lifestyle and health section. Very great health articles which I’ve saved many of! I was going to cancel after the intro rate, but I like the paper so much that I kept it up!
I just bought a iPad case off catch paid in full. I thought it was strange so looked the name up. And after seeing some of the comments on here I cancelled my card. I definitely didn’t sign up with epoch or buy anything from them never heard of them until yesterday. I guess the business I purchased the case from uses epoch. Epoch issues a credit immediately, however, it may take up to 5 business days for the credit to appear on your statement.
