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.

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.

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.

An Intelligence Squared debate in which Will Self argues for Brave New World and Adam Gopnik for Nineteen Eighty-Four as the better dystopian warning. It includes acted excerpts and is chaired by Jonathan Freedland.

Freeman Dyson's 2005 Boston University talk on heretical views about science and society. He questions prevailing dogmas, including his argument that climate and CO2 are a land management issue.

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.

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.

Sacha Baron Cohen's speech accepting the ADL International Leadership Award, in which he criticizes social media companies for amplifying hate and propaganda. He argues that freedom of speech is not freedom of reach.

Alexander Nix of Cambridge Analytica presents at the 2016 Concordia Summit on using big data, psychographic profiling and behavioral microtargeting in elections.

Nina Paley's TEDxMaastricht talk arguing against copyright and for copyleft and free culture. She argues that restricting ideas harms creativity and that culture belongs to everyone.

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.

A Johns Hopkins Foreign Affairs Symposium debate between former NSA and CIA director Michael Hayden and constitutional law professor David Cole, moderated by Major Garrett. They argue over NSA surveillance, its constitutionality and the balance between privacy and security.

An excerpt of the 2005 Harvard debate in which Steven Pinker gives his prepared case on biological sex differences and the under-representation of women in science. It covers cross-cultural patterns in preferences and abilities and the overlap between male and female distributions.

Lawrence Lessig's Talks at Google presentation based on his book Republic, Lost, arguing that money in politics corrupts Congress and eroded public trust, and outlining what could be done about it. It supports the argument with data on political donations.

Justice Antonin Scalia's opening statement at a 2011 Senate Judiciary hearing on the role of judges. He argues that the Constitution's separation of powers is what protects liberty, and that gridlock is by design.

MIT's Prof. Dennis Whyte explains the ARC/SPARC compact tokamak approach, in which new high-temperature superconducting magnets allow smaller and cheaper fusion reactors. He covers fusion physics, performance trends and the engineering path to net energy.

In this TED talk, Lawrence Lessig argues that American politics is corrupted by Congress's dependence on funding from a tiny fraction of citizens. He uses rapid-fire visuals and calls for a bipartisan push to reclaim the Republic.

Cory Doctorow's 28c3 keynote argues that the copyright wars were just a skirmish and that the real fight will be a war on the general-purpose computer. He explains why locked-down devices, DRM and surveillance tools all depend on removing general computation.

Cory Doctorow's Talks at Google lecture on the coming civil war over general-purpose computing. He argues that locked-down devices, DRM, and surveillance threaten user control of computers.

Harvard law professor Lawrence Lessig argues that US democracy is corrupted by money, since a tiny fraction of the population effectively funds who gets elected. He says fixing this must come before addressing issues like climate change or student debt.

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.

Nickolas Means recounts the 1979 Three Mile Island accident minute by minute, from the control rod insertion to the operator's decision to switch off emergency cooling. He argues that finding systemic causes is more useful than blaming individuals.
