1. The Black Death and timing of the Little Ice Age will be discussed in the context of greenhouse gases and climate change from Chapter 3 in the Online Weather Studies textbook.
2. Earth's worst historic flood which killed 1 to 3.7 million along the Huang He in China in 1931 will be studied in the context of the online investigation "Visualizing Climate," which includes the Asian monsoon, and with reference to the supplemental information on “Flood Statement Terminology.” Since floods along the Huang He are due to more than seasonal precipitation, human-environment interactions and river dynamics will also be discussed.
3. The Dust Bowl in the U.S. has been linked through climate model reconstructions to unusually cold tropical sea surface temperatures in the Pacific. This will be discussed with reference to the online supplemental information on monitoring drought and on monitoring El Nino and La Nina.
4. The discovery of the jet stream prior to World War II by Ooishi using balloons and, later, the initial failure of B29 bombers to hit their targets in Japan during WWII will be covered in the context of the online investigation "Westerlies and the Jet Stream" plus supplemental information on “Jet Streaks.”
