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.

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.

Geoff Lawton documents a permaculture project that turned barren Jordanian desert into green, productive land. It covers the techniques he used.

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.

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.

Sabine Hossenfelder explains why hydrogen is a poor answer for decarbonization, covering how most hydrogen comes from fossil fuels, the efficiency losses of green hydrogen and reliance on rare metals in fuel cells.

Real Engineering explains why biofuels, especially corn ethanol, are a poor energy source, looking at energy inputs, efficiency and carbon cost.

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.
