Marine Isotope Stage 11 (Paleogeography 🦕)
Marine Isotope Stage 11 or MIS 11 is a Marine Isotope Stage in the geologic temperature record, covering the interglacial period between 424,000 and 374,000 years ago. It corresponds to the Hoxnian Stage in Britain and the Holsteinian in Central Europe. Interglacial periods which occurred during...

By sheer curiosity
You seem interested for real in #paleology and probably even #paleoclimatology
Could you remind me the map of Earth, and the distribution of waters, the ocean level, at the epochs that you consider manageable: I think your point of view shows some amateurism, but I am not expert
A 113-million-year-old mass extinction event of marine planktic foraminifera was driven by severe ocean acidification caused by massive volcanic carbon dioxide emissions. Microscopic fossil evidence confirms that acidic surface waters dramatically reduced the ability of these organisms to build calcium carbonate shells.

Recent geological research reveals that Earth's temperatures over the past 540 million years were significantly cooler than previously estimated, demonstrating that our planet's climate has been tightly regulated by natural stabilization processes over time.

The rate-mismatch hypothesis posits that global mass extinctions occur when the pace of environmental change outstrips the rate at which biological life can undergo evolutionary adaptation. It provides a mathematical model linking Earth's historic extinction events to the critical disparities between environmental shifts and species' adaptive capabilities.

In today’s episode, we are diving into a fierce academic debate that completely strips away our human hubris: Can modern civilization survive the sheer velocity of current climate change? On one side, historians argue that human ingenuity is an unmatchable force—that we are evolutionary bottleneck survivors who can engineer our way out of any corner.

Our entire modern world—our mega-cities, our massive global supply chains, our rigidly optimized agricultural zones feeding eight billion people—is that colossal boulder. It seems permanent. It feels immovable.
But it is balancing on an incredibly narrow, highly specific set of environmental conditions.
And right now, the system is sliding into deep, systemic instability.

For ten thousand years, as waves crashed, currents shifted, and the land heaved upward, it hasn't budged. It has remained perfectly, inexplicably balanced.
Until now.
#Spikstenen is the perfect visual metaphor for the #Holocene baseline—the remarkably stable climate epoch that allowed human civilization to flourish.
Podcast Intro: The Nail Stone Metaphor
If you travel about twenty-five kilometers north of Nyköping in southern Sweden, out in the quiet landscape of Ripsa, you will stumble across a geological anomaly known as #Spikstenen.

It is the defining geophysical and
evolutionary question of our era.
And the answer is actively being
written into the sediment right now.
We hope this comprehensive
look at the geophysics
and paleoclimatology
empowers you to rigorously
question assumptions,
to look past short-term
economic narratives, and to continually
view our immediate future through the vast,
unforgiving timescale
of Earth's deep history.

Quotes from the podcast's conclusion:
Will our geological
legacy be the species
that understood its own
deep history precisely
enough, that read the
geochemistry well enough
to decentralize and
save its own future?
Or will we merely
register as a short-lived,
hyperthermal anomaly
in the strata, just a
razor-thin, dark band of rapidly deposited
carbon and synthetic plastics, remembered
by the Earth only as a brief,
violent fever it had to break?
The hyperarid core of the Atacama Desert in Chile established its extreme dryness approximately 45 million years ago. This establishes it as one of the longest continuously dry terrestrial environments on Earth.

• Tropical Heat: Sea-surface temperatures in the tropics exceeded 35°C, and perhaps even 40°C, while average land temperatures in the tropics topped 40°C.
• Giant Reptiles: Because they are cold-blooded and thrive in heat, reptiles grew to enormous sizes; the most famous was #Titanoboa, a 15-metre-long snake weighing over a tonne that roamed a humid, tropical world.

A Sweltering Hothouse World
During the PETM, the Earth was transformed into a "world of hell" as global average temperatures shot up by 5°C to 8°C over a period of about 3,000 years. The world was vastly different from today:
• Life at the Poles: The polar regions were ice-free and so warm that palm trees thrived in Siberia and alligators swam in the Arctic Ocean.
The pre-historic mirror of the PETM
The Palaeocene–Eocene Thermal Maximum (PETM), which occurred approximately 56 million years ago, serves as a "prehistoric mirror" for our future because it represents one of the most rapid and intense natural heating events in Earth's history. By studying this period, paleoclimatologists can observe how the planet’s systems—including the oceans, atmosphere, and biosphere—respond to a massive, sudden injection of carbon.
Genomic analysis of extinct cave lions reveals they represent a highly distinct evolutionary lineage that diverged from modern lions over 1.5 million years ago, significantly earlier than previously estimated.

A recent study reveals that a devastating 2012 wildfire in the high-altitude alpine moorland of Africa's Rwenzori Mountains was the first large-scale blaze in the region in at least 12,000 years. This unprecedented event signals a modern threat to unique tropical alpine ecosystems driven by a shifting climate and human activity.

During the Late Miocene epoch, massive volcanic eruptions in the Andes deposited nutrient-rich ash into the Southern Ocean, triggering widespread marine algae blooms that simultaneously fueled the evolution of gigantic whales, caused localized mass mortality events, and significantly cooled the Earth by drawing atmospheric carbon dioxide into the sea.

Analysis of a 16-meter sediment core from Lake Yoa in Chad reveals that the "African Humid Period" (14,800 to 5,500 years ago) was not a continuously wet era, but was instead abruptly interrupted by severe, decadal-scale droughts.
