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.

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.

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.

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.

Vaclav Smil's talk on historic energy transitions and what they imply for climate investment. He argues that transitions are slow, technology improves gradually, and only absolute cuts in energy use would truly work.

Allan Savory's TED talk arguing that desertification of grasslands can be reversed with holistic managed grazing, which he says would also help reverse climate change. TED notes that other scientists have challenged his claims.

A short film from Agenda Gotsch introducing syntropic agriculture and Ernst Gotsch's agroforestry methods, made for COP21. It shows degraded land regenerated into productive forest farms.

Planet of the Humans, a full documentary by Jeff Gibbs presented by Michael Moore, arguing that the green movement has been co-opted by corporate and wealthy interests and that techno-fixes are not enough.

Climate Town argues for moving away from gas stoves. It covers the gas industry's decades of marketing and lobbying, health effects of gas cooking, methane leaks, and the case for induction.

Historian and journalist Gwynne Dyer gives a long UBC talk on how climate change will reshape international politics. He covers food, borders, refugees and the possibility of unilateral geoengineering by affected nations.

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.

Jean-Marc Jancovici lectures at ENS Paris on whether energy use, jobs and growth can all be preserved. He argues for a physical approach to economics, since resource depletion and climate limits make perpetual GDP growth unrealistic.

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.

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 Virginia Tech presentation by Sid Smith about collapse, fossil fuels and overshoot, arguing that industrial civilization faces a decline and how one might live with that. It was later expanded into a video series.

David MacKay's TEDxWarwick talk uses basic arithmetic to show how much land and energy renewables would need to power a country like the UK. It explains the limits of sustainable options and why they should still be pursued.

Climate Town gives a comedic, fast-paced account of how the plastics industry promoted recycling, including the resin-code recycling symbol, while knowing most plastic could not be economically recycled. It points viewers to the Frontline documentary Plastic Wars for a deeper treatment.

Michael Shellenberger argues in a TEDx talk that solar and wind need huge amounts of land and mining, and says nuclear power is a better path to protecting both the climate and nature.

A Daily Show with Jon Stewart segment from 2014 covering the People's Climate March in New York and a House science committee struggling with basic global warming facts. It mixes satire with an argument against climate denial.

Energy scholar Vaclav Smil argues that global energy transitions are slow and that renewable targets should not rest on wishful thinking. He appraises how energy dependencies are likely to change and asks for using much less.

David MacKay, scientific advisor to the UK energy department, gives a Harvard talk on sustainable energy at macro and micro scale, drawn from his book Sustainable Energy Without the Hot Air. It stresses the land area renewables require.
