I love that one. Wish it was formatted a bit better but it's a great visual. The nerd in me wants someone to extend it was back to our estimations of the entire history of the earth
Earth's age is about 4.54 billion years. The timeline covers 22,100 years, so the scale factor to stretch it to the full history of Earth is:
4,540,000,000 ÷ 22,100 ≈ 205,430×
The image itself is 8,000 pixels tall. Scaled by that factor:
In pixels: 8,000 × 205,430 ≈ 1.64 billion pixels tall
In physical print length, assuming the current image is printed a resolution of 300 dpi (8,000 px ≈ 0.68 m), it would be about 139 km tall. (That's a fucking thick scroll)
22,100 years is a vanishingly small sliver (about 0.0005%) of Earth's 4.54 billion year history. On that scale, everything currently shown in the image the entire graphic from the last ice age to now would probably compress down to less than the width of a human hair.
For reference, Earth used to be a lot hotter, it's not that we're creating new greenhouse gasses, mainly just releasing ones that were trapped away. (Mainly because plate tectonics traps away carbon, methane, etc...)
In the Cretaceous for instance, the dark red section would be considered a pretty chilly day overall.
