I just received a very cool graphic from my friend and former student who is currently living under the ice at the South Pole. She is very excited about the implications of this graphic.
To read this, imagine yourself on a certain date (x axis). Now, follow a line down from top to bottom and see when the sun is up vs. down. This shows the change in “day length” across the year.
But if you are on the south pole, it is essentially binary. Sunup, or sundown.
Now, go find today’s date on the graph for the south pole and see why my friend is getting exited!
