I'm reading the second story, "The Myth Of Rain" by Seanan McGuire. The myth she's talking about is the persistent belief, despite the evidence, that there would be enough rain in California to end the drought.
I'm finding this story spookily prescient. The book was published in 2015 so when I read a reference to this year, I know it was a guess but it reads like news headlines. Here's what I mean:
"The thing about lies is that no matter how often you tell them and how much you believe them, they’re not going to become true. “Fake it until you make it” may work for public speaking and falling in love, but it doesn’t stop climate change.
By 2017, it was pretty clear who the liars were, and they weren’t the scientists holding up their charts and screaming for the support of the public. By 2019, it was even clearer that we’d listened to the lies too long. The tipping point was somewhere behind us, overlooked and hence forgotten."
