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.

Sabine Hossenfelder explains how the greenhouse effect actually works, given that infrared is mostly absorbed low in the atmosphere already. She walks through why more CO2 still warms the surface.

Climate Town tells the history of the period when the greenhouse effect was not politically controversial and the US came close to acting on climate. It covers Exxon's early climate science and the policy failures that followed.

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.

Climate Town's comedic explainer on carbon offsets and whether companies can buy their way out of climate change. It argues that offsets won't save us, while granting they are not bad in principle.

Sabine Hossenfelder explains that waste heat from ever-growing energy use could eventually boil the oceans in a few centuries, whatever the energy source. She discusses proposed ways to cool the planet.

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.

Sabine Hossenfelder explains climate sensitivity and why recent observations suggest climate models may have underestimated warming. She says this changed her view on how worried to be.
