New research challenges the link between the 2022 Hunga Tonga volcano eruption and the record-breaking global temperatures in 2023 and 2024.
There have been a lot of mysteries lying around the climatic impact of the 2022 Hunga Tonga volcano eruption. However, new research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler revealed that the eruption actually contributed to cooling the Earth, similar to other major volcanic events.
However, Hunga Tonga’s eruption presented a unique scenario: As a submarine volcano, it introduced an unprecedented amount of water vapor into the stratosphere, increasing total stratospheric water content by about 10%.Their researchers analyzed satellite data observations of aerosols and water vapor, among other variables, to estimate the energy balance of the Earth’s climate system.
“Our paper casts doubt on the explanation that the eruption caused the extreme warmth of 2023 and 2024,” Dessler explained. Instead, we need to focus primarily on greenhouse gases from human activities as the main cause of the warming, with a big assist from the ongoing El Niño.”According to Dessler, this research has important implications for both scientists and the general public.
While this paper answers several important questions, Dessler acknowledges that it simultaneously introduces new ones.

Aerosols shown to increase size of cloud cells, causing greater radiative cooling under polluted conditionsAerosols, often emitted alongside greenhouse gases, can brighten clouds and cause significant cooling. However, the uncertainty associated with aerosol–cloud interactions (ACIs) is large and potentially significant enough to mask a sizable portion of greenhouse gas-related warming.
