When Indonesia's Mount Tambora erupted in 1815, it unleashed the most destructive wave of extreme weather the world has witnessed in thousands of years. The volcano’s massive sulfate dust cloud enveloped the Earth, cooling temperatures and disrupting major weather systems for more than three years. Communities worldwide endured famine, disease, and civil unrest on a catastrophic scale.

Here, Gillen D’Arcy Wood traces Tambora’s global and historical reach: how the volcano’s three-year climate change regime initiated the first worldwide cholera pandemic, expanded opium markets in China, and plunged the United States into its first economic depression.

This is far from the only example. Regarding the medieval Little Ice Age, in an article by BBC Environment correspondent Richard Black, quoted a study by an international research team "studied ancient plants from Iceland and Canada, and sediments carried by glaciers". The article concludes that:

"...a series of eruptions just before 1300 lowered Arctic temperatures enough for ice sheets to expand.

The new study, led by Gifford Miller at the University of Colorado at Boulder, US, links back to a series of four explosive volcanic eruptions between about 1250 and 1300 in the tropics, which would have blasted huge clouds of sulphate particles into the upper atmosphere."

This climatic disruption negatively impacted populations worldwide. Crop failures resulting in famine and widespread starvation was just one such. According to a study by a NASA scientist: "The transition from a warm climate to the Little Ice Age in the early 14th Century, marked by heavy precipitation, may have set the stage for a series of plagues, including the Black Death". But it is what happened subsequently, when after a couple of hundred years or so Mother Earth warmed up again, that is interesting. One of the primary triggers of the Renaissance is attributed to precisely the warm-up following the Little Ice Age.

Historic climate trends have irrefutable results. Cooling baaaaad. Warming good.

I believe EVERYTHING stated here - a very impressive historic composition of Earth changes. What I propose is the ALL that happened BEFORE the world had the HUGE population increases that we have had in the last 50 years (there are graphs Of that). NOW we have a DIFFERENT world where the population is large enough and the availability of CO2 producing automobiles and locally of golf carts with zero pollution control - that availability worldwide is HUGE.
......We are living in a completely DIFFERENT situation than 150 years ago (before the invention of the automobile).
.......But, I DO appreciate your post!!!!!
