The eco scam. Sure it all might be true, but as long as it can be beneficial it will be a scam.

In December 2021, an eruption began on Hunga Tonga–Hunga Haʻapai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean. The eruption reached a very large and powerful climax nearly four weeks later, on 15 January 2022

The eruption produced a massive eruption column, reaching elevations of 57 kilometres (35 mi) and thus reaching into the mesosphere.[73] This is the highest recorded eruption column since Krakatoa’s in 1883, which extended up to 80 km (50 mi) high. The column developed multiple "umbrella"-like clouds, a higher one in the stratosphere and a lower at about 17 km (11 mi) elevation,[74] and generated a terrestrial gamma-ray flash.[75] The column injected a large quantity of water into the stratosphere, where it disturbed the local temperature balance and caused the formation of anomalous winds.[76]

Large volcanic eruptions can inject large amounts of sulfur dioxide into the stratosphere, causing the formation of aerosol layers that reflect sunlight and can cause a cooling of the climate. In contrast, during the Hunga Tonga–Hunga Haʻapai eruption this sulfur was accompanied by large amounts of water vapour, which by acting as a greenhouse gas overrode the aerosol effect and caused a net warming of the climate system.[77] One study estimated a 7% increase in the probability that global warming will exceed 1.5 °C (2.7 °F) in at least one of the next five years,[78] although greenhouse gas emissions and climate policy to mitigate them remain the major determinant of this risk.[79] Another study estimated that the water vapor will stay in the stratosphere for up to eight years, and influence winter weather in both hemispheres.[80] More recent studies have indicated that the eruption had a slight cooling effect.
