If things had gone well, America would still be in the Paris Agreement on climate change, green energy would be spreading across the country and Al Gore wouldn't have needed to make a sequel to An Inconvenient Truth. But it didn't work out that way. With his new movie hitting theaters next week, Gore remains hopeful during these depressing times. "If somebody told me five years ago, marriage equality would be the law in all 50 states, I would have asked what they were smoking," says the former vice president. "But it did happen, because it became a choice between right and wrong. That's where the climate movement is now."

Mike Sacks is not just a comedian; he's also a comedy historian. This summer, he's unearthed a rare artifact, the cult classic, Dixie-fried action movie Stinker Lets Loose. "Some famous people have cited this movie as a big influence on them," says Sacks, citing Nirvana frontman Kurt Cobain. "You can hear it in some of his lyrics, for sure." A 40th-anniversary novelization of Stinker is available now, with an intro by Sacks.

Maria Konnikova returns to look at a tool prosecutors have used for decades: handwriting analysis, or graphology. Older versions of the practice have used handwriting to predict everything from a person's mental state to their capacity for murder. "People have been convicted based on it," says Konnikova. "We're not talking about phrenology. Graphology is still something that exists in the United States. There are societies of graphologists." Konnikova is the author of The Confidence Game and host of the Panoply podcast The Grift. For the Spiel, Trump's voting commission may be hobbled, but it can still do some real harm.

Economist Tyler Cowen is disdainful of social media, heartened by recent immigrants, and wary of pot. He thinks that, in our collective desire for comfort, we are postponing big and necessary changes that will sow instability in the years ahead. "Right now Americans are failing to regenerate sources of future progress," Cowen writes, "and thus they are borrowing against the future rather than paying their bills." Cowen's latest book is The Complacent Class. In the Spiel, are things going any better abroad? Learn more about your ad choices. Visit podcastchoices.com/adchoices

Our friend Dan Pashman from the Sporkful podcast returns to explain the new field of study known as gastrophysics and why our brains have a big influence over how we taste food. For example, research shows we like the taste of food served with heavy cutlery and ice cream presented with brighter colors. "It could be something evolutionary," says Pashman.

Retired Admiral James Stavridis wants to remind us: Despite headlines about the rise of ISIS, there are bigger existential threats to America. "Terrorism is not apocalyptic, it's a tool," says Stavridis. He warns that conflicts with Russia and China are much more worrisome and likely to include a maritime component. "Again and again when there's a crisis, the first question from the president is, where are the [aircraft] carriers? They are flexible and they can strike." His new book is Sea Power.

The jobs report has been good, the U.S. isn't in a shooting war, and the economy is booming. So why is Trump still in the high 30s in terms of popularity? Political scientist Seth Masket says it's because of Trump's abrasive presence on Twitter. Masket recently made the case for why it's in everyone's best interest for the president and the social media giant to part ways in the Pacific Standard.
