We thought the Hunga Tonga volcanic eruption of January 2022 worth a mention because te climate psyop crew appear to be avoiding mentioning it.

50 million tons of water vapor from Tonga’s eruption could warm Earth for years

The explosive event increased atmospheric water vapor by 5%.

Recently, researchers calculated that the eruption of Hunga Tonga-Hunga Ha’apa spewed a staggering 50 million tons (45 million metric tons) of water vapor into Earth’s atmosphere, in addition to enormous quantities of ash and volcanic gases. This massive vapor injection increased the amount of moisture in the global stratosphere by about 5%, and could trigger a cycle of stratospheric cooling and surface heating — and these effects may persist for months to come, according to a new study.

Tonga’s eruption, which began on Jan. 13 and peaked two days later, was the most powerful witnessed on Earth in decades. The blast extended for 162 miles (260 kilometers) and sent pillars of ash, steam and gas soaring more than 12 miles (20 km) into the air, according to the National Oceanic and Atmospheric Administration (NOAA).

Recent eruptions have also demonstrated volcanoes‘ planet-cooling powers. In 1991, when Mount Pinatubo in the Philippines blew its top, aerosols spewed by this mighty volcanic blast lowered global temperatures by about 0.9 degrees Fahrenheit (0.5 degrees Celsius) for at least one year, Live Science previously reported.

Tonga expelled approximately 441,000 tons (400,000 metric tons) of sulfur dioxide, about 2% of the amount spewed by Mount Pinatubo during the 1991 eruption. But unlike Pinatubo (and most big volcanic eruptions, which happen on land), underwater Tonga’s volcanic plumes sent “substantial amounts of water” into the stratosphere, the zone that extends from around 31 miles (50 km) above Earth’s surface down to around 4 to 12 miles (6 to 20 km), according to the National Weather Service (NWS).

In underwater volcanoes, “submarine eruptions can draw large parts of their explosive energy from the interaction of water and hot magma,” which propels huge quantities of water and steam into the eruption column, scientists wrote in a new study published Sept. 22 in the journal Science. Within 24 hours after the eruption, the plume extended over 17 miles (28 km) into the atmosphere.

The researchers analyzed the amount of water in the plumes by evaluating data gathered by instruments called radiosondes, which were attached to weather balloons and sent aloft into the volcanic plumes. As these instruments rise through the atmosphere, their sensors measure temperature, air pressure and relative humidity, transmitting that data to a receiver on the ground, according to the NWS.

Prior research into the eruption found that Tonga ejected enough water vapor to fill 58,000 Olympic-size swimming pools, and that this prodigious amount of atmospheric moisture could potentially weaken the ozone layer, Live Science previously reported.

In the new study, the scientists also determined that these enormous quantities of water vapor could indeed modify chemical cycles that control stratospheric ozone, “however, detailed studies will be required to quantify the effect on the amount of ozone because other chemical reactions may play a role as well.”

The Liberty Beacon Project is now expanding at a near exponential rate, and for this we are grateful and excited! But we must also be practical. For 7 years we have not asked for any donations, and have built this project with our own funds as we grew. We are now experiencing ever increasing growing pains due to the large number of websites and projects we represent. So we have just installed donation buttons on our websites and ask that you consider this when you visit them. Nothing is too small. We thank you for all your support and your considerations … (TLB)
