The world faces a one in six chance of a major volcanic eruption this century, scientists warn, and ‘mankind. they have no intention of dealing with it.’
Such, according to the climate professor Dr. Markus Stoffel, it could cause a ‘climatic upheaval’ similar to the 1815 eruption IndonesiaMount Tambora.
That explosion it released 24 cubic miles of gas, dust, and rock in the atmosphere, causing global warming.
Crops failed, famine spread, disease spread, and thousands died.
Unlike the ‘Year Without a Summer’ that followed the eruption of Tambora, a major eruption in the 21st century will add to the disruption already caused by human dependence. burning oil.
‘The results may be worse than in 1815,’ geologist Dr. Michael Rampino explained. ‘The world is unstable now.’
But the irony is that the global warming that has been released over the past 100 years can make this eruption much cooler.
Another volcanologist Dr. Thomas Aubry’s research shows that a hot, turbulent atmosphere can disperse sulfur dioxide—and the cooling sulfate gas it produces—more quickly, increasing the cooling rate.
This time last year, a volcano on the island of Reykjanes in Iceland erupted and opened a 2.5-kilometer-long crater that spewed out a massive amount of lava every second (above). Earth has a one in six chance of a major volcanic eruption this century, scientists warn
The upcoming event, said climate professor Dr Markus Stoffel, ‘will cause climate chaos’ like the 1815 eruption of Mount Tambora in Indonesia. Above, the astronaut image (above) shows the ‘caldera’ of Mount Tambora ‘caldera’ of Mount Tambora.
A wider spread of solar-reflective aerosols can make them more effective in reducing their chance of colliding and climbing.
‘There is a sweet spot in terms of particle size and brightness,’ said Cambridge astronomer Dr Anja Schmidt – the ‘optimal’ size that is most effective at rescattering sunlight.’
Our future and climate change, according to research written by Dr Aubry Nature Communications in 2021, it will remove 30 percent of the solar energy in some cases of ‘global warming’ that are coming soon.
“We think this could increase water cooling by 15 percent,” Dr Aubry said.
But there are also troubling uncertainties, as Dr Stoffel, who teaches at the University of Geneva, said. CNN.
‘We are just at the beginning to get an idea of what can happen,’ he said.
When it comes to ancient volcanoes, ‘we have very little data,’ Stoffel explained, making it difficult to model their impact.
To pay for it, climate scientists, geologists and other researchers pull up fossils that have been frozen over time inside the glaciers and incorporated into the past. tree rings.
These measurements show that several volcanic eruptions in the past few thousand years temporarily cooled the earth by about 1 to 1.5 degrees Celsius.

The great eruption of 1815 Tambora, for example, brought it down average global temperature is about 1 degree Celsius.
And geological evidence suggests that another major volcanic eruption in Indonesia in 1257, the great Samalas event, may have helped usher in the ‘Little Ice Age,’ for centuries.
The 1991 eruption of Mount Pinatubo in the Philippines, by contrast, is best known for cooling the Earth for several years by about 0.5 degrees Celsius, based on the latest satellite data that can be captured large amounts of sulfur dioxide were released.
Even with these additional sensors and other seismic equipment, scientists still do not know the future of the volcano.
Stoffel said: ‘Which one and when, that is impossible to predict.’
The hope is that research into potential impacts can help people and policymakers better plan, for everything from evacuation to food aid planning in the event of a global crop failure.
The eruption of the 21st century may affect a densely populated and interconnected world where major disruptions may return in deadly and unpredictable ways.
Climate change could also change the behavior of the volcanoes, according to Dr Aubry, who suggested that the melting and melting of the ice on top of the underground magma pool could raise the pressure that prevents it.
Lava from the December 2023 eruption on Iceland’s Reykjanes peninsula (above) could have been fueled by melting glaciers – which reduced the weight that kept the hot magma trapped inside the Earth. ‘So we can expect more eruptions,’ warned the scientists
It’s really raining, it’s raining a lot climate change, could also trigger a ‘steam bomb’ explosion as moisture seeps into cracks near volcanic and non-eruptive volcanoes alike, he said.
“We are currently working to map the mountains most affected by climate change,” Dr Aubry said Pictures of Polytechnique this October.
“In short, we know that this affects areas where the ice is melting fast, like Iceland or Chile, and mountains that are more affected by rain, like in Indonesia,” he said.
Another 2022 study found that about 716 volcanoes worldwide, or 58 percent of those known to be active and above ground, could cause heavy rainfall, Dr Aubry explained, raising the possibility of a dangerous mini-Ice Age.
‘So we can expect a possible explosion,’ he said.
