NCC: Tonga volcano eruption will raise global temperatures by 1.5 degrees

The journal Nature Climate Change published a study by Oxford University scientists who estimated global temperature changes due to the Tonga volcanic eruption.
The experts concluded that the impact would be large enough to temporarily raise average global temperatures by 1.5 degrees Celsius above the limit. This limit was set by the Paris Agreement in 2015.
Climatologists detected a warming effect of 0.12 watts per square meter shortly after the explosion. The scientists used transport models to estimate the likely increase in global mean temperature over a 10-year period.
The result is a high probability that average global temperatures will exceed 1.5 degrees Celsius.
In January 2022, due to the eruption of the underwater volcano Hunga Tonga-Hunga-Hunga, Haapai released a huge amount of ash, gas and water into the atmosphere. A huge amount of water thrown out – 146 tons – had a warming effect. Most of the water has reached the stratosphere, therefore, it will take many years for it to settle back to Earth.
