Talk:Volcanic winter

Albedo
When the earth's reflectivity increases, you are RAISING the albedo, not lowering it. --Bagshotrow (talk) 15:03, 19 March 2009 (UTC)

Silly question
To ask a silly question: if it was too cold to snow, what did the winters after the volcanic winter but before 1888 bring?

"the next four years were unusually cold, and the winter of 1888 was the first time it was warm enough to snow; snowfalls that year broke all records worldwide."

too warm to snow....

Sources?
Practically all of this article - especially the first bit - is sourceless. Is it correct but sourceless, or wrong as well? William M. Connolley 15:38, 30 March 2006 (UTC)

Sources: data in dispute
The first two sections are sourceless. Further, some of the stated 'facts' are in dispute. In particular, there is no evidence in Greenland ice cores for a prolonged period of dramatic (i.e., about 3 K) cooling. (See C. Oppenheimer(2002), Quaternary Science Reviews 21:14--15, pp. 1593--1609, who states the evidence from the ice cores gives about 1 K cooling.)

Per PBS-Nova the volcanic super eruption of 75,000 years ago was in East Africa, not Sumatra. Is this new information that should be included? —Preceding unsigned comment added by 108.85.227.15 (talk) 09:12, 21 May 2011 (UTC)

Error in lead paragraph: explaining my correction
The lead paragraph has contained this sentence: "The volcanic aerosols, resulting from the 1991 Pinatubo eruption and others, have been shown to contribute to anthropogenic ozone depletion.[3]" This sentence isn't right. Aerosols from volcanoes are the opposite of anthropogenic. I took a brief look at the ref. by Solomon et al., where the relevant sentence appears to be: "Volcanically driven increases in Antarctic ozone depletion were documented in the early 1990s after the 1991 eruption of Mount Pinatubo and are well simulated by models (15, 16). " I think the Wikipedia editor confused the word "Antarctic" with the word "anthropogenic". But the sentence has another problem: the article (as a whole) is about changes in temperature, rather than ozone depletion. I am therefore deleting the sentence. But the reference by Solomon et al. is good enough that I am preserving its code by pasting it below, in case someone wants a different correction than the one I've made. Comments, anyone? Do you think I did this correctly? Oaklandguy (talk) 05:09, 19 February 2018 (UTC)


 * You could also have solved the problem by just removing the word "anthropogenic". However, it isn't desperately relevant to this article William M. Connolley (talk) 07:40, 19 February 2018 (UTC)

"volcanic autumn" as opposed to "volcanic winter", in some cases
In particular for the (relatively) less powerful eruptions like in 1883 and 1991, it would be more appropriate to talk about a "volcanic autumn" than a "volcanic winter", since following the Krakatoa and Pinatubo eruptions respectively, the drop in global temperatures was slight though real and perceptible, and it didn't result in major global disruption in the food supply and so forth the way the previous events on the list (the 1815 Tambora eruption being the last such event until now) did. — Preceding unsigned comment added by Therav (talk • contribs) 15:50, 2 January 2022 (UTC)


 * Unless any reliable sources actually use the term "volcanic autumn", probably not. Millows (talk) 02:36, 1 July 2023 (UTC)
