Last August, NASA reported that the Tonga volcano eruption blasted an amount of water vapor into the stratosphere that has not been seen before. In fact, the volcano ejected approximately 146 million tons of water vapor into the stratosphere- that is the equivalent of 13% of the water vapor that was already there, a 5-fold increase of stratospheric aerosol load. Since water vapor is 4 times more effective at being a greenhouse gas than is carbon dioxide, it’s responsible for about half of Earth’s greenhouse effect.
The January eruption of the underwater volcano saw the catapulting of millions of tons of water vapor dozens of miles into the upper reaches of the atmosphere, where it is usually not as prevalent. This greatly increased the greenhouse effects of water vapor and raised global temperatures. (pdf warning)
That’s why everything was fairly normal until mid-March 2023, and then a dramatic 1°C warming spike in a matter of 2-weeks raised global temperatures to the record levels we are at today. We are going to be stuck with higher than normal temperatures for the next few months. So don’t let those with a political agenda tell you that this is man’s fault. This is nature at work. Science, it’s a thing.
