"Unleashing Fury: The Impact of the 2022 Tonga Volcanic Eruption on Global Climate"

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai in Tonga caused a temporary warming effect over the Pacific, potentially pushing global temperatures beyond the 1.5 degree Celsius threshold set by the United Nations. While volcanic eruptions typically have a cooling effect due to the release of sulfur, this eruption carried an unusually large amount of water vapor into the stratosphere, acting as a greenhouse gas and raising temperatures. This study predicts an additional 7% probability of exceeding the 1.5 degree Celsius threshold, emphasizing the need to address human contributions to climate change.
