Valóban semmi új keletû nincs az egészben, esetleg új részletek lehetnek. A Laki közelében túrázva olvasgattunk errõl mi is, tényleg elég komolyan foglalkoztak már a témával. A francia forradalommal kapcsolatos közvetlen okozati összefüggést azért "kimondott igazságnak" nem merném nevezni, mondjuk azt, hogy vannak ilyen elméletek is.
Mindenesetre a közvetlen következmények leírását tömören összefoglalja ez az idézet is:

"The Effects of the Skaftáreldar Eruption on Other Countries
The sulphurous cloud from the eruption gradually spread across most of the northern hemisphere,
affecting the climate across a wide area.
Two days after the onset of the eruptions, the cloud of gases had become a mist that reached
the Faroe Islands, Norway and Scotland. By the middle of June, it spread across mainland Europe.
By June 24, a black mist hung over all of Europe, reaching as far as Finland and covering countries
as distant as the Balkans. The European press portrayed the sun as a blood-red disc at sunrise
and sunset. They wrote that the midday sun shone so dimly that people could look at it directly
with the naked eye.
By July the mist had reached Russia, Siberia and China. At its peak, it covered one quarter
of the earth’s surface – all of the land north of latitude 30°N.
After Iceland, the ecological effects of the mist were felt most in the other Nordic countries,
Western Europe and the British Isles, causing crop failures. The acid rain defoliated trees and
withered smaller plants. The overall temperature dropped by 1.3 °C (2 °F). The cold spell lasted
three years with harmful effects reaching around the world. The mist penetrated even the farthest
parts of the planet. As quickly as the very summer of 1783 there was a serious failure of Japan’s
rice crop caused by cold and wet weather, resulting in the worst period of famine in Japan’s
written history. Similar stories came out of Alaska, where entire townships died out.
The French Revolution marked a turning point in the evolution of republicanism and civil rights.
One theory suggests that the French Revolution had its roots in Laki, when, as previously mentioned,
the effects of the mists had altered weather patterns across Europe."
