Environment & Climate

Climate and the environment are discussed constantly and explained rarely, which leaves a lot of confident vocabulary sitting on shaky foundations. This category covers the underlying science: what the atmosphere is made of, how the greenhouse effect actually works, what photosynthesis contributes, and which energy sources renew and which do not. It also covers the major international agreements. The explanations stick to established, well-evidenced science and describe mechanisms rather than arguing policy, since the physics and the politics are separate questions and only one of them belongs in a quiz.
