When climate scientists say things are going to be horrendous, people find out many years later that we’re right. With this El Niño, the “find out” part will come in months.

EVs are awesome. I have a Hyundai Ioniq 5, which has a range of 300-350 miles. I charge it at home, which is convenient, and it costs me about $10 to completely recharge the battery. (84 kWh at 12 cents a kWh) Compare that to a similar size gas car, at 25-30 mpg, which would cost $54 to fill up.

Google Gemini says that @jevinwest.bsky.social and I aren't to be trusted because in our first lecture, we had a playful example where Jevin presented data the same way that Tim Cook did, and I called bullshit on it. It hallucinates criticism and the only citations are to the lecture itself.
1. The "Explosive Growth" Slide ControversyIronically, the most direct and explicit example of this occurred during their very first "Calling Bullshit" lecture at the University of Washington.The Setup: Jevin West presented a slide to the class showing a graph that purported to show the "explosive, hockey-stick growth" of web traffic to their new Calling Bullshit website. The graph utilized standard marketing axes and compressed timeframes to make the project look like an unmitigated, runaway viral sensation.The "Bullshit": Carl Bergstrom actually had to step in and call "bullshit" on his own co-instructor's slide. When the data was displayed honestly without selective axis truncation or creative smoothing, it showed that while traffic was high initially, it heavily ebbed, flowed, and plateaued over time.The Criticism: While some praised this as a playful, planned pedagogical moment to show that "anyone can fall prey to bad data framing," critics viewed it as a perfect illustration of the double standard: when it serves a personal or professional promotional narrative (like proving your own course is a massive success), the temptation to use flawed, hype-driven metrics is incredibly high.
