lifecycle emissions

Engineering Explained compares the lifecycle emissions of keeping an old car with those of buying a new, more efficient one. It weighs manufacturing emissions against emissions from driving, and covers gas versus electric cars.

Engineering Explained compares the lifetime CO2 emissions of a Toyota RAV4 Prime plug-in hybrid with a Tesla Model Y, looking at break-even mileage and whether electric cars are worse for the environment.

Engineering Explained works through whether electric cars are really worse for the environment than gasoline cars. It covers battery production emissions, the electricity mix used to charge, and how long an EV takes to break even on lifetime emissions.

Everyday Astronaut's Tim Dodd runs an hour-long, data-driven analysis of what rockets actually emit and how that compares with airliners and other industries. It breaks down exhaust by propellant type, per-passenger and total emissions, and ways launches could be cleaner.

Engineering Explained examines new research suggesting corn ethanol in US gasoline may emit as much or more carbon than gasoline. It covers the Renewable Fuel Standard and why ethanol was assumed to be a green fuel.

Kurzgesagt examines who is responsible for climate change, comparing historical, current and per-capita emissions by country. It argues that individual footprints are a distraction from larger responsibility.

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.

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.

Elon Musk gives students at the Sorbonne a short, simple explanation of climate change and carbon emissions shortly before the 2015 COP21 conference in Paris. He covers why CO2 accumulation matters and argues for a carbon tax.

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.

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

Jean-Marc Jancovici gives an MIT Media Lab talk on whether technology can save us from climate change. He argues from a physical view of energy that economic growth, energy use and climate impact are tightly linked.

A clip from The Newsroom season 3 in which characters argue that the climate change debate is over and only a technology to reverse emissions can help.

A one-minute demo at the Computer History Museum's IBM 1401 restoration lab, where a program makes the machine's radio-frequency interference play tunes on an AM radio.

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.

Excerpts from Nick Breeze's 2012 interview with researcher Natalia Shakhova about methane release from the East Siberian Arctic Shelf. She discusses the risk of abrupt methane emissions.
