Supposedly, the Hunga Tonga-Hunga volcano that erupted in 2022 is the cause of this heat

The current heat wave is being relentlessly blamed on increasing levels of carbon dioxide in the atmosphere, but there is a much more plausible explanation, one that is virtually endorsed by two of the world's leading scientific organizations. It turns out that levels of water vapor in the atmosphere have dramatically increased over the last year and a half, and water vapor is well recognized as a greenhouse gas, whose heightened presence leads to higher temperatures, a mechanism that dwarfs any effect CO2 may have.

So why has atmospheric water vapor increased so dramatically? Because of a historic, gigantic volcanic eruption last year that I — probably along with you — had never heard of. The mass media ignored it because it took place 490 feet underwater in the South Pacific. Don't take it from me; take it from NASA (and please do follow the link to see time-lapse satellite imagery of the underwater eruption and subsequent plume of gases and water injected into the atmosphere):

When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in the South Pacific Ocean also blasted an enormous plume of water vapor into Earth’s stratosphere – enough to fill more than 58,000 Olympic-size swimming pools. The sheer amount of water vapor could be enough to temporarily affect Earth’s global average temperature.

The eruption of the submarine Hunga volcano in January 2022 was associated with a powerful blast that injected volcanic material to altitudes up to 58 km. From a combination of various types of satellite and ground-based observations supported by transport modeling, we show evidence for an unprecedented increase in the global stratospheric water mass by 13% relative to climatological levels, and a 5-fold increase of stratospheric aerosol load, the highest in the last three decades. Owing to the extreme injection altitude, the volcanic plume circumnavigated the Earth in only 1 week and dispersed nearly pole-to-pole in three months. The unique nature and magnitude of the global stratospheric perturbation by the Hunga eruption ranks it among the most remarkable climatic events in the modern observation era, with a range of potential long-lasting repercussions for stratospheric composition and climate.
