1. Impacts on the survivability of Sacramento’s population

1.1 Will Sacramento have enough drinking water?

Set on a freshwater delta upriver from an ocean bay, Sacramento’s signature climate worry is saltwater flooding. On a map, Sacramento looks to be so far inland from the Pacific Ocean, you’d think it couldn’t possibly be affected by the rising sea. But the complex network of streams and canals and wetlands that Sacramento sits on is effectively an an inland extension of the San Francisco Bay. The Bay is rising with the warming Pacific Ocean. The salty ocean water will be pushing further and further into the area around Sacramento, where several rivers (freshwater) meet.

Saltwater contaminates freshwater, making it unsuitable for drinking or farming. Without monumental infrastructure improvements for saltwater inundation, huge swaths of Sacramento Valley farmland will be lost. Vast populated regions south of Sacramento will need to have water pumped from further upstream in the Sierra Mountains. Problem is, the Sierra’s dwindling snowpack is holding less and less water for the region’s growing 10,000,000s (tens of millions) of people. And less water will be causing billions of dollars worth of food to not be grown.

1.2 Sacramento’s lush landscape makes the city tinder for epic wildfires.

California’s fire season has been getting more and more extreme, by far, during the 2010s. In nearby Paradise, CA, 85 people died, and 19,000 homes and 27 downtown businesses were reduced to ash in November 2018. The timing and severity of the fires are attributable to the warming atmosphere. The fire season in California used to be something that only happened during the warmer months of the year. Now, all year long, places like verdant Sacramento are subject to monster wildfires.
