global warming:

a data-driven investigation

AIRS_forcing_v0.mp4

(what am I looking at?)

Plotted data in black/grey are measurements. Red is spectroscopic modeling. If the two overlap, it means that the models are doing a good job of mimicking reality. The left two panels are analysis of 18 years (18 TB) of satellite data, which took me 3 years and $1,800 to finish.

(what am I looking at?)

Just like visible light is composed of individual colors at different wavelengths, so too is infrared light emitted from Earth at various wavelengths. Those particular wavelengths of infrared that are intercepted by CO₂ molecules show a decline in brightness over time (as CO₂ concentration rises).
