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.

Cliff Click walks through a small performance example on a modern out-of-order CPU. He covers pipelining, ILP, CISC vs RISC, multicore, and why cache misses and the memory subsystem dominate performance.

Clip from Lex Fridman's podcast with Roger Penrose in which Penrose argues that consciousness is not a computation. He discusses Godel-style arguments and the possible role of quantum effects in microtubules.

A clip from Lex Fridman's podcast in which chip architect Jim Keller argues that Moore's Law is not dead and that transistor scaling still has lots of room. He also discusses how to break down hard problems.

Technosociologist Zeynep Tufekci argues that the machine-learning systems used to serve ads also decide what political and social information people see. She explains how opaque algorithms can nudge, segment and manipulate users, and warns that the real danger is powerful people using AI to control populations.

Potholer54 presents the climate science case and a market-oriented, conservative-friendly approach to addressing global warming, with sources listed. It is part one of a two-part series.

A 1978 documentary hosted by Leonard Nimoy about the coming ice age, reposted with a framing that contrasts it with today's climate science.

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 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.

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.

A FRONTLINE documentary on whether efforts to fix plastic pollution made it worse. It looks at the battle over plastics and recycling and how little plastic is actually recycled.

John Oliver explains how plastics harm the planet and why recycling is not the solution consumers have been led to believe. He argues corporations and policymakers must act, not just individuals.

Not Just Bikes tours Houten, a Dutch town designed around cycling, explaining how its layout makes most trips by bike safe and easy. It also promotes a book about the town.

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.

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.

Joe Scott takes a serious look at space sunshades as a climate fix, asking how big they would need to be, what they would cost and whether they would work. He draws on Roger Angel's paper and launch options.

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.

Wendover Productions examines why carbon offsets so often fail to reduce emissions, covering specific examples and the perverse incentives in offset schemes.

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 that waste heat from ever-growing energy use could eventually boil the oceans in a few centuries, whatever the energy source. She discusses proposed ways to cool the planet.

Veritasium's Derek Muller explains his hypothesis that YouTube's algorithm, not viewer preference, drives views, and that click-through rate has become the key metric. He argues this pushes creators toward clickable titles and thumbnails and leads to burnout.

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.

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

Patrick Boyle examines why birth rates are falling in nearly every country and argues the standard explanations do not hold up. He presents data suggesting fewer couples forming is a major driver.
