Tonga Underwater Volcano Eruption May Have Had a Larger Warming Effect Than Reported

CR Editor’s Note: This volcanic eruption water vapor estimate analysis given on Twitter by meteorologist Ryan Maue shows that the recent eruption of an underwater volcano near Tonga may have resulted in a larger warming effect than scientists originally reported. 

Initial scientific estimates were 50 million metric tons of water injected into the stratosphere by the Hunga Tonga-Hunga Ha’apai submarine volcano. [emphasis, links added]

These estimates are likely off by a factor of three.

New research suggests 150 million metric tons or almost 40 trillion gallons of water vapor was injected into the upper atmosphere.

A lot of it is still up there floating around.

The 40 trillion gallons of water vapor in the stratosphere represents an unprecedented amount injected into the stratosphere.

Volcanic eruptions like Pinatubo blast SO2 into the stratosphere, creating a cooling climate shroud for 1-2 years.

But, Hunga Tonga had only 2% of the SO2 as Pinatubo but a gargantuan amount of water vapor, which is well known to WARM the Earth.

The question is how much?

The global warming caused by Hunga-Tonga is significant. The eruption of Hunga-Tonga increased the water vapor mass in the stratosphere by 13%, and it will remain there for many years to come.

“The unique nature and magnitude of the global stratospheric perturbation by the Hunga eruption rank it among the most remarkable climatic events in the modern observation era.”

In early March 2023, scientists reported the likelihood of warming from the volcanic injection of water vapor into the stratosphere pushing Earth closer to the 1.5°C Paris Agreement threshold.

Based upon the last few months, it seems the effect of [the volcano] on global temperatures may have been greatly underestimated.

It’s straightforward how to run a radiative transfer model to determine the impacts of adding 150M metric tons of water to the stratosphere.

But, detailed climate model simulations are needed to disentangle the atmospheric circulation changes that lead to non-linear feedback.

The climate is “abnormal” right now, aside from the developing El Niño and background climate change.

    While the Globalist Depopulation Cabal use net zero to close farms, stop use of oil, coal and natural gas–all to reduce CO2 the gas of life–we know it’s all about reducing population not climate change! if this stunning volume of water injected into the atmosphere results in more warming it might drive these global nuts to more Draconian restrictions! Restricting CO2 restricts us while no one can control water vapor. Ah yes, back to the point it’s all about reducing population…………..

    Of course this information will not make it into the news. Nor will the so-called “climate scientists” will take this into account for their models and update anything related to the eruption.

    There has been a lot of noise about this year being the “warmest ever.” The clear implication is we need to make big sacrifices to reduce our emissions. Events like the Tonga Eruption will be ignored even though increasing the water vapor mass in the stratosphere by 13% is extremely significant.
