Adam Something gives a short, sarcastic argument that carbon capture does not live up to its promises. He says the energy it uses would be better spent replacing fossil sources directly.

A Kurzgesagt animated explainer on the climate and environmental cost of meat. It covers how beef drives deforestation and emissions, and how this compares with plant-based foods.

Veritasium examines whether food has become less nutritious, weighing soil depletion, selective breeding and rising atmospheric CO2. It evidences nutrient decline even in weeds over a century and ties it to faster plant growth.

Researcher Kamal Meattle describes how an arrangement of three common houseplants placed in specific spots can measurably clean the air in a home or office. It is a short TED talk based on his work in a plant-filled building.

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.

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.

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.

Mark Rober makes a plant-based burger for Bill Gates and explains why meat production strains the environment. Gates also appears and discusses his worry about steel and cement.

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 1971 DEC LAB-8/e (PDP-8/e) minicomputer plays music by inducing noise into a nearby AM radio. The software is Richard Wilson's 1975 Music Compiler running under OS/8.

Fully Charged rides a 100% battery-electric ferry across the 4 km strait between Helsingborg, Sweden and Helsingør, Denmark. The ferry crosses up to 46 times a day and charges for a few minutes at each side. The video shows the charging setup, including the robot arm that couples the charger.

A 2007 Channel 4 documentary by Martin Durkin arguing that human-caused global warming is overstated or a scam. It features contrarian scientists such as Richard Lindzen and promotes sunspot and cosmic-ray explanations for temperature change. Its claims are rejected by mainstream climate science.

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