A Kurzgesagt video on the conditions in which most farm animals are raised. It argues that cruelty is for cheaper rather than better meat, and that a small price increase per meal could avoid most of the suffering.

Sabine Hossenfelder explains climate sensitivity and why recent observations suggest climate models may have underestimated warming. She says this changed her view on how worried to be.

Sabine Hossenfelder explains how the greenhouse effect actually works, given that infrared is mostly absorbed low in the atmosphere already. She walks through why more CO2 still warms the surface.

The first video in potholer54's climate series, giving a basic look at how climate scientists infer that man-made carbon gases are changing the climate. It is a short explainer meant to present the scientific evidence plainly.

Kurzgesagt's animated take on climate change argues that, despite alarming headlines, there are real reasons for hope as technology, policy and public attitudes shift. It surveys trends and solutions while acknowledging the scale of the problem.

Climate Town traces the history of American parking minimums, how they came from shaky research and ITE guides, and how they shape zoning, cities and housing costs. It is a long, comedic video essay.

Veritasium argues that Facebook's ad revenue relies partly on fake likes, after paying to promote his page and gaining tens of thousands of followers in developing countries who never engaged. He shares his experiment and cites other cases.

Vox Earworm explains why John Coltrane's Giant Steps is so hard to improvise over: it is fast and moves through three keys. Musicians Braxton Cook and Adam Neely walk the host through the underlying music theory.

Tom Scott tells how John Reber's plan to dam San Francisco Bay was disproved by the Army Corps of Engineers' giant hydraulic Bay Model in Sausalito. The model showed the plan would have been dangerously wrong.

Rick Beato analyzes a pop song he argues is among the most harmonically complex ever, breaking down its chords and key changes. It is a music theory deep dive aimed at general music fans.

Kurzgesagt examines what individuals can do about climate change, covering lesser-known carbon sources and why systemic and political change matter more than personal footprints.

Joseph Everett, with Dr. Frank Mitloehner, argues that eating less meat will not do much for the climate. He covers beef's water footprint, land and feed use, and methane.

A four-minute Not Just Bikes comparison of grocery shopping in Amsterdam versus car-centric North America, arguing that frequent small fresh-food trips beat bulk shopping. It ties this to land use and reduced food waste.
