So what do you think a future species archaeologists' will make of the Anthropocene Epoch when they dig down?

There is little doubt now that we have entered a new geological age, believes an international scientific panel.
The team, which has been tasked with defining the so-called Anthropocene, says humanity's impacts on Earth will be visible in sediments and rocks millions of years into the future.
The researchers are working towards a formal classification of the new epoch.
An open question is the formal start date, which some panel members think could be the 1950s."

"Amused To Death"

Doctor Doctor what is wrong with me
This supermarket life is getting long
What is the heart life of a colour TV
What is the shelf life of a teenage queen
Ooh western woman
Ooh western girl
News hound sniffs the air
When Jessica Hahn goes down
He latches on to that symbol
Of detachment
Attracted by the peeling away of feeling
The celebrity of the abused shell the belle
Ooh western woman
Ooh western girl
And the children of Melrose
Strut their stuff
Is absolute zero cold enough
And out in the valley warm and clean
The little ones sit by their TV screens
No thoughts to think
No tears to cry
All sucked dry
Down to the very last breath
Bartender what is wrong with me
Why I am so out of breath
The captain said excuse me ma'am
This species has amused itself to death
Amused itself to death
Amused itself to death
We watched the tragedy unfold
We did as we were told
We bought and sold
It was the greatest show on earth
But then it was over
We oohed and aahed
We drove our racing cars
We ate our last few jars of caviar
And somewhere out there in the stars
A keen-eyed look-out
Spied a flickering light
Our last hurrah
And when they found our shadows
Groups 'round the TV sets
They ran down every lead
They repeated every test
They checked out all the data in their lists
And then the alien anthropologists
Admitted they were still perplexed
But on eliminating every other reason
For our sad demise
They logged the only explanation left
This species has amused itself to death
No tears to cry
No feelings left
This species has amused itself to death
Amused itself to death

It's pretty obvious Jeff and we're just getting started. An with too many brains and not enough wisdom.

I have read that enough concrete has been made to pave the whole earth's surface with one kilo per square meter. Leave out the oceans……….

But the bacteria will likely survive.

I think, as a geologist, that the clear marker will be nuclear testing. Lots of other things may have volume, but radiation is forever( or just about)

Don't forget the thin layer of plastic sludge. The reset of the carbon cycle is more like 100,000 years, and the oil will be gone forever.

With that gloomy thought (thanks Adam;)) here's something from 1979 to brighten up your morning...

That's an interesting graph in #4, but the 'global carrying capacity' line is purest nonsense.

Half of the concrete ever made, was produced in the last 20 years. Enough for 1 kilo for every square meter of the Earths surface!

Marks of the Anthropocene: 7 signs we have made our own epoch


Even if humanity is long gone (https://www.newscientist.com/article/mg21128221-900-existence-will-we-die-out) in tens of millions of years, there will still be a clear sign of us and the way we lived left preserved in our planet’s geological record.
There is now overwhelming evidence that our impact on Earth constitutes its own distinct geological epoch, dating from the middle of the 20th century. Here are the seven signs that will clearly identify the Anthropocene epoch (https://www.newscientist.com/article/mg22429940-200-is-earth-in-a-new-geological-phase-thanks-to-us) for future geologists.
1.Nuclear weapons

Our war efforts have left their mark on geology. When the first nuclear weapon was detonated on 16 July 1945 in New Mexico, it deposited radionuclides – atoms with excess nuclear energy – across a wide area. Since 1952, more explosive thermonuclear weapons have been tested, leaving a global signature of isotopes such as carbon-14 and plutonium-239.
2. Fossil fuels

The products of burning fossil fuels will also be an obvious giveaway of the Anthropocene. Current rates of carbon emission (https://www.newscientist.com/article/dn28469-carbon-emissions-hit-new-high-and-temperature-rise-soars-to-1-c)are thought to be higher than at any time in the last 65 million years. The concentration of carbon dioxide in the atmosphere has risen sharply since 1850 and now exceeds 400 parts per million, which will be recorded in anyAntarctic ice cores (https://www.newscientist.com/article/mg21028105-100-the-hunt-is-on-for-million-year-old-ice-core) that manage to survive global warming. Burning fossil fuels has also increased the ratio of carbon-12 to carbon-13 isotopes, which will be detectable in tree rings, limestone, and fossilised bones and shells. Our fuel consumption also spreads small, unburned particles of carbon in the air, which can become captured in sediments and glacial ice.
3. New materials

One of the biggest signs of our time will be the presence of three things we use every day: concrete, plastics and aluminium. Aluminium (https://www.newscientist.com/article/mg22530102-300-cheap-wonder-metals-will-make-a-faster-cleaner-world) in its elemental form was unknown before the 19th century, but we have now produced around 500 million tonnes of it. Concrete (https://www.newscientist.com/article/mg22229720-100-the-idyllic-tropical-island-now-covered-in-concrete) has been around for longer – it was invented by the Romans – but in the 20th century it became our most widely used building material. We have now produced about 50 billion tonnes of the stuff – enough to spread a kilogram on every square metre of Earth – and more than half of that was made in the last 20 years. Plastics (https://www.newscientist.com/article/dn28242-plastic-in-the-food-chain-artificial-debris-found-in-fish), initially developed in the 1900s, have grown rapidly since the 1950s, and we now produce 500 million tonnes a year. Sediments containing any of these materials will be a clear sign of the Anthropocene.
4. Changed geology

Every time we destroy a patch of rainforest, this changes the future of Earth’s geology. So far, we have transformed more than 50 per cent of Earth’s land area for our own purposes. Deforestation (https://www.newscientist.com/article/dn27056-amazon-deforestation-soars-after-a-decade-of-stability), farming, drilling, mining, landfills, dam-building and coastal reclamation are all having widespread effects on sedimentary processes, disrupting how layers of rock are laid down, which will be detectable thousands of years in the future.
5. Fertilisers

Our attempts to feed a burgeoning population will leave clear indicators, too. Levels of nitrogen and phosphorus (https://www.newscientist.com/article/dn18575-earths-nine-life-support-systems-nitrogen-and-phosphorus-cycles) in soils have doubled in the last century because of our increased use of fertilisers. We produce 23.5 million tonnes of phosphorus a year, twice the rate seen during the previous epoch, the Holocene. Human activity has had perhaps the biggest impact on the nitrogen cycle for 2.5 billion years, increasing the amount of reactive nitrogen (https://www.newscientist.com/article/mg21428666-200-why-we-should-care-about-our-nitrogen-footprint)by 120 per cent compared to the Holocene.
6. Global warming

Anthropogenic climate change will be easily distinguishable in the future. Last century, Earth’s temperature rose (https://www.newscientist.com/article/dn26122-no-more-pause-warming-will-be-non-stop-from-now-on)by between 0.6 and 0.9 °C, more than the amount of natural variability seen in the Holocene, which has been calculated based on the oxygen isotopes in Greenland’s ice cores. Average global sea levels are higher than at any point in the past 115,000 years and are rising rapidly (https://www.newscientist.com/article/mg22630253-300-latest-numbers-show-at-least-5-metres-sea-level-rise-locked-in), which may also be detectable in future.
7. Mass extinction

For as long as life has existed, organisms have gone extinct, but mass extinctions (https://www.newscientist.com/article/mg20928022-100-mass-extinctions-a-brief-history-of-catastrophe) sparked by massive global changes (https://www.newscientist.com/article/mg20928022-200-mass-extinctions-the-terrible-two)mark the end and beginning of several geological periods. Some estimates predict that we are on our way to the sixth mass extinction (https://www.newscientist.com/article/dn4797-earth-faces-sixth-mass-extinction)event in Earth’s history, with three-quarters of species set to be wiped out in the coming centuries. Palaeontologists of the future will notice the sudden disappearance of many species from the fossil record as the Anthropocene gets under way.

the 1950's might be said to be the beginning of the atomic age or the end of WWII
