Still in awe of yesterday's huge science drop about that 9-day monochromatic seismic wave revealing a climate-induced glacial collapse that sent the equivalent of 10 Giza Pyramid's worth of rock and ice into a Greenland Fjord, creating a 200m high Tsunami.
That's about the red line in this diagram of the Eiffel Tower and Sydney's Centrepoint Tower.
And that's not even the coolest part. The 9-day seismic signal was the result of a 7m wave sloshing back and forth in the narrow fjord, with a period of 90 seconds, as the water slapped against the valley walls.
