Trudeau: I think Canadians are a little perplexed as to why our closest friends and neighbors are choosing to target us.
I don’t think there are a lot of Americans who wake up in the morning saying, "Oh, damn Canada. Oh, we should really go after Canada."

The last great Cascadia subduction zone earthquake occurred 325 years ago today at 9:00 PM local time. How do we know so precisely? Here’s the story.

Today is the 325th anniversary of the ~M9 1700 Cascadia megathrust earthquake + tsunami, the most recent major quake on the Pacific Northwest's subduction zone. An event that size could happen again any day. Video here shows how scientists figured out when it happened (9pm). youtu.be/A1R6B6_2KOk?...

We’re almost out of the cold…
Today is the coldest day for Minnesota with average temperatures returning by midweek. Dry, Siberian air has shoved the storm track along the Gulf Coast, and 2-5"+ of snow may shut down Houston and New Orleans on Tuesday with a couple inches of snow/ice into the FL Panhandle

On Jan 6 1912, Alfred Wegener presented his theory of continental drift and supercontinent Pangaea's breakup into today's continents. Despite initial rejection, modern seismology and ocean drilling in the 1950s/60s validated his ideas, leading to the current understanding of plate tectonics. ⚒🧪

4.5 billion years ago: Proto-Earth collides with the Mars-sized protoplanet named Theia, partially merging, but a large chunk bounces back into space. In less than 2 million years, two gravitationally locked new bodies form - Earth and Moon 🌑🌙
