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.

Bill Gates at Stanford's Global Energy Forum argues that cheaper solar, wind and storage are not nearly enough to stop climate change. He discusses natural gas, a carbon tax, nuclear, battery costs and the responsibilities of developing versus developed economies.

In this TEDxBerlin talk, environmental activist Michael Shellenberger explains why he changed from opposing nuclear power to advocating it, after looking at the evidence on Chernobyl, Fukushima and air pollution.

A snarky, comedic video essay from Climate Town, with a guest appearance by Not Just Bikes, arguing that American suburban sprawl and single-family zoning are financially and environmentally unsustainable. It covers how zoning rules shape housing and what viewers can do locally, such as attending zoning meetings.

A documentary from Swan Bitcoin exploring Bitcoin's relationship with energy, featuring Lyn Alden and others, and arguing that mining is a net positive for the environment and not wasteful.

Geoff Lawton documents a permaculture project that turned barren Jordanian desert into green, productive land. It covers the techniques he used.

A Last Week Tonight segment explaining carbon offsets, what they claim to do, and how they may worsen climate change. It looks at perverse incentives and questionable projects.

A 2015 interview in which physicist Freeman Dyson, then 91, argues that global warming concerns are exaggerated, that CO2 is beneficial and that climate models oversimplify complex systems. It is posted on a channel that opposes climate consensus.

A Climate Town episode on who uses America's water, particularly Western water. It looks at agriculture such as alfalfa and animal feed, and at water-rights rules that discourage conservation.

Arthur Keller gives a roughly half-hour crash course on environmental collapse, covering exponential growth, carrying capacity and ecological overshoot.

Sabine Hossenfelder weighs the arguments for and against nuclear power, covering waste, fuel supply and newer reactor designs. She is skeptical that fast breeders and thorium solve the problems.

Sabine Hossenfelder explains why hydrogen is a poor answer for decarbonization, covering how most hydrogen comes from fossil fuels, the efficiency losses of green hydrogen and reliance on rare metals in fuel cells.

Tom Chi gives the opening talk of a Foresight Institute competition on clean energy and clean air, framing excess CO2 as a carbon debt to repay and discussing large-scale tree planting, including by drone.

Bill Gates' TED2010 talk on the energy future, arguing for zero global carbon emissions by 2050 and the need for energy miracles. He explains why he is backing a different type of nuclear reactor.

Thunderf00t critiques the TeamTrees campaign, doing the math on how little carbon 20 million trees would actually offset. He argues that tree planting is far from adequate against global emissions.

Bryan Cantrill's OSCON 2015 talk on moving a proprietary product to open source, drawing on Sun's history with Solaris and illumos, licensing choices and the relicensing after Oracle's acquisition.

A 29-minute cinematic timelapse by melodysheep that journeys trillions of years into the future, covering the death of the sun, the end of stars, proton decay, black hole evaporation and the fate of the cosmos.

Explains the proposed NASA JPL plan to use the Sun as a gravitational lens, sending solar sail craft to its focal region to image an exoplanet's surface. It covers the distances involved, how imaging with the Sun would work and the mission design.

PBS Space Time explains the proposal to use the Sun's gravity as a giant lens, sending a train of small light-sail spacecraft to the focal point roughly 550 AU out. It covers how such a telescope could image exoplanets in surprising detail and the engineering challenges involved.

Utah State plant scientist Bruce Bugbee presents his analysis of the energy and environmental costs of vertical and indoor farming. He argues artificial lighting cannot compete with sunlight in fields or greenhouses.
