Visual depictions of CO2 levels and CO2 emissions:
Diversos vídeos, e todos eles bastante pedagógicos. Só se reproduz o primeiro: "Measurements of atmospheric carbon dioxide come from more than a

scattered across the globe taking direct measurements. Three
independent satellites take global CO2 measurements: the Atmospheric
Infrared Sounder (AIRS) on the NASA Aqua spacecraft, Envirosat by the
European Space Agency and IBUKI by the Japan Aerospace Exploration
Agency. For periods before direct measurements, CO2 can be determined
from Antarctic and Greenland ice cores. Here are some visual summaries
of CO2 data:[...]"
