Scientists Identify 1831’s Mystery Volcano That Cooled the Earth

[Social Media]

 

In 1831, an immense volcanic eruption altered Earth’s climate, causing temperatures in the Northern Hemisphere to drop by an average of 1 degree Celsius. Nearly 200 years later, scientists have finally pinpointed the source of this mysterious eruption: Zavaritskii volcano on Simushir Island, part of the Kuril Islands archipelago in the northwest Pacific Ocean.

 

This event, one of the most powerful eruptions of the 19th century, released vast quantities of sulfur dioxide into the stratosphere. It coincided with the final stages of the Little Ice Age, a period of notable cooling that lasted from the early 1400s to around 1850. Despite the eruption's climatic impact, the volcano responsible remained unidentified for decades due to limited historical records and its remote location.

 

 

Dr. William Hutchison, a principal research fellow at the University of St. Andrews, explained the challenges of uncovering Zavaritskii’s eruptive history. "For many of Earth’s volcanoes, particularly those in remote areas, we have a very poor understanding of their eruptive history,” he said. “Zavaritskii is located on an extremely remote island between Japan and Russia. No one lives there, and historical records are limited to a handful of diaries from ships that passed these islands every few years.”

 

 

The breakthrough came through an innovative analysis of ice cores from Greenland. Layers of sulfur isotopes, volcanic ash, and glass shards deposited between 1831 and 1834 pointed to a midlatitude volcano in the Northern Hemisphere. Geochemical analysis and computer modeling ultimately led researchers to Zavaritskii, a volcano whose last known eruption had been in 800 BC. “The moment in the lab analyzing the two ashes together — one from the volcano and one from the ice core — was a genuine eureka moment,” Hutchison shared.

 

While earlier studies misattributed the 1831 eruption to tropical volcanoes like Babuyan Claro in the Philippines, new findings highlight the Kuril Islands as a source of significant climatic disruptions. Dr. Stefan Brönnimann, a climatologist at the University of Bern, emphasized the importance of this discovery. “This eruption had global climatic impacts but was wrongly attributed to a tropical volcano for a long time period. The research now shows that the eruption took place on the Kurils, not in the tropics.”

 

The impact of the eruption extended far beyond the Northern Hemisphere's cooler temperatures. The resulting environmental changes contributed to widespread famine and hardship across India, Japan, and Europe. “It seems plausible that volcanic climate cooling led to crop failure and famine,” Hutchison said. “A focus of ongoing research is to understand to what extent these famines were caused by volcanic climate cooling or by other socio-political factors.”

 

The identification of Zavaritskii adds to a broader understanding of the role of volcanic activity in shaping Earth’s climate. Alongside other eruptions, such as Tambora in Indonesia in 1815 and Cosegüina in Nicaragua in 1835, it underscores the significant impact of volcanic eruptions during the Little Ice Age. 

 

Hutchison stressed the importance of monitoring isolated volcanoes like Zavaritskii, as future eruptions could have devastating global consequences. “We don’t really have a coordinated international community to kick into gear when the next big one happens,” he warned. “That is something we need to think about as both scientists and as a society.”

 

By shedding light on the mysterious 1831 eruption, this research highlights the delicate interplay between natural events and human history and the need for vigilance in the face of Earth’s unpredictable geological forces.

So, what they're saying is that the climate changes independent of human forces.

 

But we need to spend redistribute $trillions of dollars.

So, this caused a 1 degree drop.  So the recent rises are just a rebalancing after this natural disaster?

Right, nature regulates itself. Volcanic activities are the earth thermostats. Amazingly the chains of volcanoes are well distributed on each continent in order to spread its mineral benefits (as well as a reminder of its mighty power).

Such an immense reservoir of energy.

It was a brief change. As the aerosols dissipated the cliimate returned to normal. Nnlike particles in the atmosphere generated by volcanoaes, carbon dioxide, methane, nitrous oxide, and other greenhouse gases don't fall to earth in relatively short order.

Your comment would make sense if the baseline used to measure average atmospheric temperature, dates from the year of that drop. But it doesn't so your comment is false.

What is it about rates that anthropogenic climate change denialists don't understand. No one questions that climate changes over time. It's the rate of change that's the issue.

That is why there are 6 documented Glacial and Inter-Glacial periods

If you look again at my comment you’ll see it has a question mark at the end. So, that means my comment was a question not a statement. If it was a statement then your reply would be valid, whether I agree or not. As it was a question then your reply is rude. Well, the last part anyhow. The rest seems a valid scientific response which I thank you for.

Well now if it goes hotter  faster than what some people may think and try to brainwash on us than naturally it will cool down faster so I evens out doesn't it.

What's seems to be the problem with that?

Your not happy with that?

Nature seems to be quite capable of looking  after itself.

Get Real , Please stop trying to brainwash people.

Better to give up, it is a dead end. Its like discussing with flat earthers and anti vaxxers.

I remember when there was a Congresswoman who said not to worry about the extinction of one species because another will come along to replace it.

Yours is that kind of thinkiing.

Why would it "naturally" come down just as fast as it went up. You think this situation is analagous to shooting an arrow straight up into the air? This is pre-scientific thinking. The laws of physics probably will see the temperature eventually come down after the level of greenhouse gasses comes down.

As for brainwashing people...you mean people who won't engage with the science and instead offer conspiracy theories?

No. This rate of change is way outside the norm. Temperatures have been quite stable for the about 2000 years. And suddenly , in line with climatologists predictions, temperatures begin to soar. What an amazing coincidence.

To be more accurate, we are in a post glacial period. Whether the glaciers extend themselves once again is not a certainty. But even if they eventually do, what's your point?

As for the Little Ice Age:

The Little Ice Age Wasn’t Global, but Current Climate Change Is

None of the cold and warm epochs from the past 2,000 years were global events, but the current period of climate change is more intense and is happening simultaneously across the entire planet...

“Statistically, the spatial coherence of the warming in the last century is totally different from the spatial coherence of any other period in the past,” says study coauthor Juan José Gómez-Navarro, an environmental physicist at the University of Murcia in Spain.
