Did the Tonga Eruption Affect the 2023 Summer Heatwave?

2023 was so hot that NASA climatologists said

July 2023 was the hottest month ever recorded . There are several possible factors, but scientists have indicated that the large-scale volcanic eruption that occurred in Tonga in January 2022 was also the cause of the heat wave.

Gloria Manney, a senior research scientist at the New Mexico Institute of Technology and Luis Millan of the NASA Jet Propulsion Laboratory, who is a senior research scientist at

NorthWest Research Associates, which conducts scientific research, told the science news site LiveScience, In other words, no,' he said.

The eruption of the Hunga Tonga-Hunga Ha'apai volcano that occurred in Tonga was certainly one of the largest volcanic eruptions in recorded history.

It is estimated that the large eruption of Tonga had more than 500 times the explosive power of the Hiroshima-type atomic bomb, comparative images before and after the eruption are also ants - GIGAZINE

Normal volcanic eruptions form sulfate aerosols that reflect sunlight from space and temporarily cool the surface of the earth. However, the eruption of Hunga Tonga-Hunga Ha'apai volcano occurred underwater, producing millions of tons of water vapor.

The water vapor content in the stratosphere has increased by 10% to 15% due to the water vapor generated by the eruption, and this water vapor may increase the average temperature of the earth by 0.035 ° C.

However, the reason why the summer of 2023 will be extremely hot is that 'climate change' is the main cause, even if there is some impact from this eruption and El Niño phenomenon.
