Notes and resources to supplement the presentation on Climate Change: A Case of Extremes as Well as Averages by Patricia MacEwen
They are listed in order as they came up on the slides.
This article provides an overview of the Greenhouse Effect and what it does both for and to us. Without it, the Earth's overall temperature would be more than 50 degrees F colder: https://en.wikipedia.org/wiki/Greenhouse_effect.
The information on the 8 worst greenhouses came from a longer list of 11: https://www.thoughtco.com/worst-greenhouse-gases-606789
The chart on carbon dioxide levels over the last 800,000 years came from NASA: https://climate.nasa.gov/vital-signs/carbon-dioxide/
The chart on methane levels over the same period includes the original sources in the image and came from: https://www.reddit.com/r/ScienceImages/comments/3h2jow/earths_methane_history_over_the_past_800,000_years/
The article I referred to on the actual death toll from heat waves in California was:
"Editorial: Climate change is fueling extreme heat. California can do much more to save lives" which appeared in the L.A. Times, and is available here:

A short explanation of the ENSO cycle with its El Nino and La Nina extremes can be found at:
What is the El Niño–Southern Oscillation (ENSO) in a nutshell? | NOAA Climate.gov (https://www.climate.gov/news-features/blogs/enso/what-el-ni%C3%B1o%E2%80%93southern-oscillation-enso-nutshell)
A longer explanation of the ENSO cycle comes from NOAA (the National Oceanic and Atmospheric Administration: Changes in ENSO impacts in a warming world | NOAA Climate.gov (https://www.climate.gov/news-features/blogs/enso/changes-enso-impacts-warming-world)
An article on US temperature averages over the last 4 decades, "The last 30 years were the hottest on record for the United States" can be found in Science News at:

Information on groundwater in the Central Valley came from: "California's Central Valley Groundwater Wells Run Dry During Recent Drought" in Earth's Future, available at: California's Central Valley Groundwater Wells Run Dry During Recent Drought - Jasechko - 2020 - Earth's Future - Wiley Online Library (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019EF001339#:~:text=Anecdotal%20evidence%20suggests%20that%20groundwater%20level%20declines%20are,recent%20drought%2C%20especially%20in%20the%20southeastern%20Central%20Valley.)
Information on water stress came from an article titled "Analysis: Global water stress by 2040" in Water World, available at:
Analysis: Global water stress by 2040 | WaterWorld (https://www.waterworld.com/international/wastewater/article/16201682/analysis-global-water-stress-by-2040)
Information on irrigation water in the Central Valley came from the California Farm Water Coalition, which tracks all kinds of related information. The report I used in this presentation came from:
Map Shows 2021 Farm Water Supply Cuts | California Farm Water Coalition (https://www.farmwater.org/farm-water-news/map-2021-farm-water-supply-cuts/#:~:text=Critical%20reservoirs%2C%20including%20Shasta%2C%20Oroville%2C%20Folsom%2C%20Millerton%2C%20and,percent%20of%20average%20at%20this%20time%20in%202015.)
Images of the recent major wildfires and related smoke came from general news reports on the Dixie and Caldor Fires, now considered the 2nd worst and all-time worst fires in California history.
