A couple years ago this global warming denier gave a talk definitively claiming the record high temperatures of 2023-24 were from this volcano. Wonder if he has changed his tune?

Key Scientific Findings
The eruption of the Hunga Tonga–Hunga Haʻapai volcano in the South Pacific on 15 January 2022 produced the largest underwater explosion ever recorded by modern scientific instruments. It injected vast quantities of water vapor into the stratosphere, increasing global stratospheric water by about 10%, much of which remains in the atmosphere through 2025.

While the eruption perturbed stratospheric ozone in the Southern Hemisphere in the months following the eruption, its overall effects on the Antarctic ozone hole and surface climate were minor.

The report emphasizes that record-high global temperatures in 2023-2024 were not caused by the eruption. Model simulations indicate that Hunga’s surface cooling influence - about 0.05 K - was indistinguishable from natural climate variability.
