How Volcanic Eruptions Cause Climate Change

I always feel really happy when I have a new product on TPT, yesterday I finished a lesson about Global Warming and the Milankovitch Cycles. The reason this peaked my curiosity is because the other day I was in a charming antique store in Oak Harbor Washington. The guy that worked there was very helpful to me, and he was also a great conversationalist. He sold me a museum replica of an ancient Greek black figure vase. I really love Greek museum replicas, some of the best things in my home come from museum stores. This vase was a great find. While we were there, an angry lady was muttering something about how human made climate change is not real because the planet has been going through glacial periods of warming and cooling for millions of years.

Technically, she's partially correct. The phenomena she’s referring to are known as the Milankovitch Cycles, which are astronomical events affecting Earth’s climate over long periods. However, human-made climate change and the Milankovitch Cycles are distinct phenomena. The truth of one does not invalidate the other.

Then I realized that what I need is one more lesson about climate Change because Volcanoes do cause ice ages. In fact, it is my opinion that a volcanic eruption caused the French Revolution. This is my rough outline for the informational text.
