^ On a related note, more Non-science and nonsense;
March for Science draws smaller crowds than last year, but attendees are still passionate

Crowds turned out in cities around the world Saturday for the second annual March for Science.

Saturday's crowds were notably smaller than those that showed up for the first march in April 2017, but attendees expressed as much optimism and hope as they did last year.

According to the non-partisan March for Science organization, the main event was set to take place in Washington, while more than 230 satellite events were scheduled around the world in different forms, be they marches, rallies or science exhibitions.
...
Participants aimed to hold public officials accountable and push them to implement policy based on scientific evidence, according to the march's website.
...
Mittleman, who works in science communications, told CNN she was advocating for "so many things!"

The foremost issue for her was how the United States and the world are being impacted by climate change, and she wanted to see more action taken to fight it.

"I also believe science education in school and beyond is vital to create future generations of scientists and develop innovative research and cure various diseases," Mittleman said. "Also to help with the communication of facts and research to help educate people that may not have the resources they need to understand science and its impact on everyone."
...

More science education and this sort of oxy-moron would be reduced.

Why is the global climatic cataclysm of the sixth century virtually unheard of?

Because there's no money in it now.

... specifically, the money in form of funds and grants for "climate research" looks to be largely slanted to finance that which will prove humans cause "Climate Change/Global Warming" rather than to more objectively understand and know climate and factors affecting it.

Was There a Civilization On Earth Before Humans?
A look at the available evidence
...
We never got back to aliens. Instead, that first conversation launched a new study we’ve recently published in the International Journal of Astrobiology. Though neither of us could see it at that moment, Gavin’s penetrating question opened a window not just onto Earth’s past, but also onto our own future.

We’re used to imagining extinct civilizations in terms of the sunken statues and subterranean ruins. These kinds of artifacts of previous societies are fine if you’re only interested in timescales of a few thousands of years. But once you roll the clock back to tens of millions or hundreds of millions of years, things get more complicated.

When it comes to direct evidence of an industrial civilization—things like cities, factories, and roads—the geologic record doesn’t go back past what’s called the Quaternary period 2.6 million years ago. For example, the oldest large-scale stretch of ancient surface lies in the Negev Desert. It’s “just” 1.8 million years old—older surfaces are mostly visible in cross section via something like a cliff face or rock cuts. Go back much farther than the Quaternary and everything has been turned over and crushed to dust.

And, if we’re going back this far, we’re not talking about human civilizations anymore. Homo sapiens didn’t make their appearance on the planet until just 300,000 years or so ago. That means the question shifts to other species, which is why Gavin called the idea the Silurian hypothesis, after an old Dr. Who episode with intelligent reptiles.

So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.

Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist? The best way to answer this question is to figure out what evidence we’d leave behind if human civilization collapsed at its current stage of development.
...
https://www.theatlantic.com/science/...zation/557180/

How this relates to Climate Change, etc.; the below hints at ...
...
The big question is how long any of these traces of our civilization will last. In our study, we found each had the possibility of making it into future sediments. Ironically, however, the most promising marker of humanity’s presence as an advanced civilization is a by-product of one activity that may threaten it most.

When we burn fossil fuels, we’re releasing carbon back into the atmosphere that was once part of living tissues. This ancient carbon is depleted in one of that element’s three naturally occurring varieties, or isotopes. The more fossil fuels we burn, the more the balance of these carbon isotopes shifts. Atmospheric scientists call this shift the Suess effect, and the change in isotopic ratios of carbon due to fossil-fuel use is easy to see over the last century. Increases in temperature also leave isotopic signals. These shifts should be apparent to any future scientist who chemically analyzes exposed layers of rock from our era. Along with these spikes, this Anthropocene layer might also hold brief peaks in nitrogen, plastic nanoparticles, and even synthetic steroids. So if these are traces our civilization is bound to leave to the future, might the same “signals” exist right now in rocks just waiting to tell us of civilizations long gone?

Fifty-six million years ago, Earth passed through the Paleocene-Eocene Thermal Maximum (PETM). During the PETM, the planet’s average temperature climbed as high as 15 degrees Fahrenheit above what we experience today. It was a world almost without ice, as typical summer temperatures at the poles reached close to a balmy 70 degrees Fahrenheit. Looking at the isotopic record from the PETM, scientists see both carbon and oxygen isotope ratios spiking in exactly the way we expect to see in the Anthropocene record. There are also other events like the PETM in the Earth’s history that show traces like our hypothetical Anthropocene signal. These include an event a few million years after the PETM dubbed the Eocene Layers of Mysterious Origin, and massive events in the Cretaceous that left the ocean without oxygen for many millennia (or even longer).
...
Etc.

I figured that, but thought it should be made clear for the others reading here.
