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 gasses 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.

“We’ve never seen anything like it,” said Luis Millán, an atmospheric scientist at NASA’s Jet Propulsion Laboratory in Southern California. He led a new study examining the amount of water vapor that the Tonga volcano injected into the stratosphere, the layer of the atmosphere between about 8 and 33 miles (12 and 53 kilometers) above Earth’s surface.

In the study, published in Geophysical Research Letters, Millán and his colleagues estimate that the Tonga eruption sent around 146 teragrams (1 teragram equals a trillion grams) of water vapor into Earth’s stratosphere – equal to 10% of the water already present in that atmospheric layer. That’s nearly four times the amount of water vapor that scientists estimate the 1991 Mount Pinatubo eruption in the Philippines lofted into the stratosphere. [emphases

NASA published the above in August 2022. Half a year later, a newer study increased the estimate of the water vapor addition to the atmosphere by 30%. From the European Space Agency:

In a recent paper published in Nature, a team of scientists showed the unprecedented increase in the global stratospheric water mass by 13% (relative to climatological levels) and a five-fold increase of stratospheric aerosol load – the highest in the last three decades.

Using a combination of satellite data, including data from ESA’s Aeolus satellite, and ground-based observations, the team found that due to the extreme altitude, the volcanic plume circumnavigated the Earth in just one week and dispersed nearly pole-to-pole in three months. [emphasis added]

Another scientific paper explains the “net warming of the climate system” on a delayed basis. NASA’s Jet Propulsion Laboratory further explains:
