Meteorologist explains how volcanic eruptions affect the climate
Summary
TLDRA massive volcanic eruption of Hunga Tonga in the South Pacific was captured by weather satellites, causing a global shockwave. The underwater volcano's unique conditions led to intense pressure and a release of water vapor, ash, and sulfur dioxide. While sulfur dioxide can temporarily cool the Earth by reflecting sunlight, this eruption's impact on climate is minimal compared to human activities. The carbon dioxide emissions from such eruptions are negligible in the context of atmospheric warming.
Takeaways
- đ A massive volcanic eruption occurred at Hunga Tonga in the South Pacific Ocean.

Q & A
What event was captured by weather satellites on Friday?
-A massive explosion from a volcano known as Hunga Tonga in the South Pacific Ocean.
What effect did the explosion have on the planet?
-The explosion produced a shockwave that traveled all the way around the entire planet.
Why was the explosion from the Hunga Tonga volcano particularly violent?
-Most of the volcano is underwater, which allowed a lot of water to seep into the magma chamber, vaporizing and producing huge pressure that blew it apart.
Who is Professor Brian Toon and what does he specialize in?
-Professor Brian Toon is a boulder professor who studies the impact of volcanic eruptions on the climate.
What key gas is emitted by volcanoes that can affect the climate?
-The key gas emitted by volcanoes is sulfur dioxide.
How does sulfur dioxide impact the atmosphere when it heats up in sunlight?
-When sulfur dioxide heats up in sunlight, it changes into droplets called sulfuric acid, which can reflect sunlight back to space.
What was observed after big volcanic eruptions that can affect the Earth's temperature?
-After big eruptions, the formation of sulfuric acid droplets can reflect sunlight, leading to a temporary cooling of the Earth.
How did the Mount Pinatubo eruption in 1991 affect the atmosphere's temperature?
-The Mount Pinatubo eruption in 1991 cooled the atmosphere by about 1 degree Fahrenheit for a little more than a year.
How does the recent eruption of Hunga Tonga compare to the Mount Pinatubo eruption in terms of climate impact?
-The recent eruption of Hunga Tonga pales in comparison to the Mount Pinatubo eruption and is not significant enough to have an obvious impact on the climate.
What is the role of carbon dioxide emitted by volcanoes in the atmosphere?
-Volcanoes emit carbon dioxide, a greenhouse gas that causes warming to the atmosphere, but its contribution is minimal compared to other sources.
According to a NASA study, how does the amount of CO2 from the Mount Pinatubo eruption compare to human daily production?
-The amount of CO2 from the Mount Pinatubo eruption is equal to the amount of CO2 that humans produce twice every day.
What is the significance of the Hunga Tonga volcano's CO2 emissions to the atmosphere according to Corey Reppenhagen?
-The concentration of CO2 from the Hunga Tonga volcano would hardly be noticeable and is not of significant interest to the carbon dioxide levels in the atmosphere at present.
Outlines
đ Massive Volcanic Eruption in Hunga Tonga
A significant volcanic eruption occurred at Hunga Tonga in the South Pacific Ocean, as captured by weather satellites on a Friday. The explosion was extraordinarily powerful due to the majority of the volcano being submerged, allowing water to infiltrate the magma chamber and vaporize, leading to immense pressure that caused the eruption. Boulder Professor Brian Toon explains that the eruption propelled water vapor, ash, and gases, including sulfur dioxide, high into the atmosphere, reaching up to 18 miles. Sulfur dioxide, when heated by sunlight, transforms into sulfuric acid droplets that can reflect sunlight back into space, potentially leading to short-term cooling effects on Earth. The 1991 Mount Pinatubo eruption serves as a historical reference, having cooled the atmosphere by about 1 degree Fahrenheit for over a year. However, the recent eruption at Hunga Tonga is not expected to have a significant impact on the climate. Additionally, while volcanoes emit carbon dioxide, a greenhouse gas, the amounts released by such eruptions are minimal compared to human activities, with a NASA study indicating that the Mount Pinatubo eruption released an amount of CO2 equivalent to what humans produce in two days. The Hunga Tonga eruption's carbon dioxide emissions are considered negligible in the context of atmospheric CO2 levels.

Transcripts
Weather satellites captured a
massive explosion from a volcano
known as Hungry Tonga in the
South Pacific Ocean on Friday.
It produced a shockwave that traveled
all the way around the entire planet.
Part of the reason the explosion
was so violent is that most
of the volcano is underwater and you know,
so there's a lot of water is probably
seeped into the magma chamber and vaporized
producing huge pressure that blew it
apart. Boulder Professor Brian Toon
says the volcano launched water vapor.
Ash and gases up into the atmosphere as
high as 18 miles tune studies the impact
of volcanic eruptions on the climate,
the key gas being emitted
is sulfur dioxide, he says.
When it heats up in the sunlight,
it changes into droplets, called
sulfuric acid, and these can
reflect sunlight back to space,
and it's been observed after
big eruptions that this has
happened and it can cool the earth
off. He says.
The Mount Pinatubo eruption in 1991
cooled the atmosphere by about.
1 degree Fahrenheit for a
little more than a year.
But this week's eruption pales in
comparison, so this particular
eruption of Hunga Tonga isn't
even close to being important.
To the climate, in a way that would
be obvious to people he believes careful
measurements will show some slight
cooling in short term temperature data,
but nothing significant.
Volcanoes also emit the
greenhouse gas carbon dioxide,
which causes warming to the atmosphere.
But tune says it's minimal
compared to other sources.
A NASA study shows the amount of CO2 that
came from the Mount Pinatubo eruption,
the largest in over 100 years,
is equal to the amount of CO2 that
humans produce twice every day.
Tune says hunger.
Tongass concentration would
hardly be noticeable.
The volcano is no nothing of any
interest to the carbon dioxide
in the atmosphere at the
present time. Meteorologist
