Around 250 million years ago, Earth faced a profound crisis known as the Permian-Triassic extinction, or “The Great Dying,” which tragically diminished nearly all life on our planet, marking its most severe biological challenge. This heart-wrenching event, uncovered through recent research, offers vital lessons for humanity today as we navigate rapid climate change, biodiversity loss, and environmental challenges.
By understanding the causes of this ancient catastrophe, we are inspired to unite in compassion and action, fostering a shared commitment to protect and nurture our planet’s precious ecosystems, ensuring a vibrant, thriving future for all life.
Earth Was Almost Lifeless 250 Million Years Ago

The Permian-Triassic extinction, far more than a fleeting moment in Earth’s story, was a profound turning point that reshaped the tapestry of life with deep and lasting impact. As our world today faces rising temperatures and CO2 levels echoing that distant past, we are called to unite in compassion to avoid repeating history’s mistakes, with the well-being of all life at stake.
Armed with greater knowledge, we have the power to act with care and urgency. Let the lessons of “The Great Dying” inspire us to nurture our planet, fostering a hopeful, sustainable future for generations to come, rather than a forewarning of loss.
What Exactly Happened?
Around 252 million years ago, at the boundary of the Permian and Triassic periods, a sequence of volcanic eruptions in what is now Siberia released vast amounts of carbon dioxide (CO2) and methane into the atmosphere. These greenhouse gases dramatically altered the Earth’s climate, raising temperatures by as much as 10 degrees Celsius globally.
The impact wasn’t just limited to warming. The climate became highly erratic, and weather patterns destabilized. Oceans turned acidic, deoxygenated, and ultimately became a toxic environment for marine life. These environmental stressors caused food chains to collapse, beginning with microscopic plankton and extending all the way up to large predators. This wasn’t just an extinction event; it was a planetary reboot.
The Smoking Gun: The Siberian Traps
What are they?
The Siberian Traps are one of the largest volcanic provinces in the world. Covering over 7 million square kilometers, they were formed by intense volcanic activity that spewed molten rock, ash, and gases over hundreds of thousands of years.
Why they matter:
The eruptions pumped trillions of tons of greenhouse gases into the air. The resulting feedback loops included:
- Warming oceans, which released even more CO2 and methane from the seabed
- Ocean acidification that hindered shell formation in marine organisms
- Mass coral bleaching and collapse of reef ecosystems
- A drop in oxygen levels that suffocated marine and freshwater species
This was climate change on steroids—and it happened in less than a few hundred thousand years.
Life on the Brink
Picture Earth as a planet in chaos:
- Forests died, turning landscapes into barren deserts
- Coral reefs vanished, eliminating shelter for countless sea creatures
- Insects and microbial life surged in some areas, but complex ecosystems crumbled
- Food webs collapsed, from the ocean floor to land animals
Scientists estimate that only a tiny fraction of Earth’s species made it through the bottleneck. Among the survivors were microbial mats, burrowing creatures, and heat-tolerant animals like Lystrosaurus, which thrived in the aftermath.
For up to 10 million years, life on Earth remained in a prolonged state of recovery, marked by low biodiversity and fragile ecosystems. The planet took its time rebuilding.
The Climate Connection
The parallels between this ancient event and today’s climate crisis are spine-chilling:
- CO2 levels are rising today at rates rivaling those during the Permian extinction
- Coral reefs are disappearing due to warming and acidification
- Extreme weather events are increasing, destabilizing both natural and human systems
- Biodiversity is plummeting with extinction rates 1,000 times the natural background rate
Many scientists believe we are entering or already in the Sixth Mass Extinction. The Great Dying stands as our closest historical mirror.
Lessons for the Modern World
1. Climate Matters
The planet’s climate isn’t just background noise. When it shifts too fast, ecosystems can’t keep up, and mass die-offs follow.
2. Carbon is Powerful
Carbon dioxide may be invisible, but its effects are visible everywhere: rising seas, mega storms, and record heat.
3. Limits of Resilience
Yes, Earth can recover. But it takes millions of years. Humanity doesn’t have that kind of time.
4. Small Changes Add Up
What seems like slow climate drift can build up until Earth crosses tipping points. That’s when things spiral fast and unpredictably.

What Scientists Are Doing
To better understand this catastrophic event and its relevance today, researchers are:
- Drilling into ancient marine sediments to examine chemical signatures
- Using climate models to simulate conditions that led to ecosystem collapse
- Dating lava flows from the Siberian Traps to correlate with extinction layers
- Comparing fossil records before, during, and after the extinction window
- Monitoring today’s coral reefs, ice cores, and atmospheric data to detect alarming parallels
Interdisciplinary teams are bringing together geology, biology, climate science, and computer modeling to paint the clearest picture possible.

FAQs
Q1: Was the Permian extinction caused by an asteroid?
A: No. This extinction was driven mainly by prolonged volcanic activity and massive CO2 emissions.
Q2: Could something similar happen again?
A: Yes. Rapid carbon release today mimics the environmental triggers of the Permian extinction.
Q3: How long did it take for life to recover?
A: Estimates range from 3 to 10 million years for full ecosystem recovery.
Q4: Did any animals survive?
A: Yes. A few tough species like Lystrosaurus and some marine sponges made it through the chaos.
Q5: Why does this matter to us today?
A: Because the mechanisms of extinction from 250 million years ago are being repeated by human activity now.
