Salient ET impacts, volcanic eruptions and climate events

Version one of this post is from memory. I plan to add links and confirm details later.

ET Impacts:

1. The Tunguska event. Russia, June 30, 1908.

2. The meteor strike that destroyed Sodom and Gomorra. Levant, 1650 BCE.

6.  Yosemite's last big eruption ca. 630,000 years ago.

Climate events:

2.  The drought in the American SE that ended ancient Puebloan culture.

4.  The horrible year: 536 CE.

5.  The Bronze Age collapse event. ca. 1200 BCE.

7.  The Green Sahara and its end. ca. 15,000 to 5,000 years ago.

8.  The Younger Dryas. ca. 12,900 years ago. Delayed the Neolthic revolution by about 3,000 years.
