Raymond Inauen, a graphic artist with 35 years’ experience, presents a free website of downloadable charts (PDF/PNG/ZIP) meant to teach CO2, climate, and energy basics or serve as a single reference. Charts cover CO2’s molecule, atmospheric composition (about 420 ppm), natural vs anthropogenic emissions (4.9% manmade), ocean/land fluxes, plant physiology (stomata), C3/C4/CAM plants, photosynthesis, and a logarithmic CO2–temperature relationship. He also includes long-term temperature/CO2 history, Holocene and recent warming, sea-level rise since the last ice age, and glacier/tree-line evidence from the Alps. Energy charts break down global fuel use and electricity sources. He adds references, a CO2 mascot “Conrad,” discusses reduced social-media reach, and shares a visual condensing atmospheric CO2 into a 16×16 km cube.
