1452-53 event

Sulfur dioxide emissions by volcanoes.

Solar radiation reduction due to volcanic eruptions

Kuwae might not be linked to the 1452-53 event (Nemeth K, Cronin SJ, White JDL (2007). "Kuwae caldera and climate confusion". The Open Geology Journal. 1: 7–11. doi:10.2174/1874262900701010007.{{cite journal}}: CS1 maint: multiple names: authors list (link)). Tofua Caldera, Tonga is cited as a candidate. On the other side the paper is probably wrong too. Non-volatile sulfuric acid is just determined in the ice core, sulfur dioxide is enough for a volcanic winter (Robock, A., C.M. Ammann, L. Oman, D. Shindell, S. Levis, and G. Stenchikov (2009). "Did the Toba volcanic eruption of ~74k BP produce widespread glaciation?". Journal of Geophysical Research. 114: D10107. doi:10.1029/2008JD011652.{{cite journal}}: CS1 maint: multiple names: authors list (link)). Basalt floods emit sulfur dioxide too (1783-1785 event), everything needs not to be emitted in one only eruption (sulfur dioxide is a reducing agent, a large sulfur dioxide emission, is measured as a sulfuric acid ice core spike in the North and the South Pole). Sulfur dioxide (boiling point at standard state: -10°C) reacts with water vapor, it creates sulfate ions (the precursors to sulfuric acid, Earth Observatory - Sarychev Eruption [1]). I hope that I'm right, though. --Chris.urs-o (talk) 15:54, 24 February 2010 (UTC)

The date

Pls note ([2]):

22 May, when it had interrupted a great battle raging at the city of Constantinople. The great “fire” that had been set by Turkish attackers was really just the reflection of ash in the twilight.

1452/1453 mystery eruption

I've split off 1452/1453 mystery eruption from this article, because there is enough question about whether this volcano truly was the cause of these climate anomalies that it should probably be separated out. Jo-Jo Eumerus (talk) 16:23, 1 March 2022 (UTC)
