#paleontology and yours truly in the world’s biggest English language newspaper! People really seem to urgently need to know where their backyard was in the Jurassic 😀 who would have thought that in 2026 #continentaldrift would enthrall the public? 😄 https://timesofindia.indiatimes.com/science/this-tool-shows-where-your-home-was-when-dinosaurs-roamed-earth-over-230-million-years-ago/articleshow/130718380.cms #geology #tectonics

What a fascinating video. While I knew about plate tectonics, I didn’t realize that continental drift was sneezed at even 80 years ago, as late as the 1940s.

How can I see more? How can I experience more of this wonderful place? That’s the mission for 2026.

#Alfred #Wegener (died November 1930 in Greenland) was a #German #geologist, #polarexplorer, and #meteorologist. He is primarily known for his #theory of #continentaldrift, which has significantly influenced modern theories of #platetectonics. Fossil discoveries and similar calving fronts along the west coast of #Africa and the east coast of #SouthAmerica led him to his theory, which is still crucial for understanding the #evolutionaryhistory of life on Earth.

"The only way we could chart the seafloor was by throwing heavy things downward. Everything that lay beneath a few miles of water might as well have been on the moon."

This just gets me thinking. I really like it:

As For The Housefly
by T.R. Hummer 2016

Bashing its head against the kitchen window,
 its sentience is a quasar, it has lived
Twenty fly years trying to understand transparency,
 while for me, only half a day has passed
Since it blew in the back door as I was getting the mail.
 But I hear the cosmos howling fiercely inside
Its minuscule cranium. Time is compressed in its soul
 like neutrons in plasma. When I walk
Across the kitchen, I am continental drift, I move
 My arms like a spiral galaxy. No wonder
It is frantic as I open the pane. How long must it take
 for the air to cool and the sun to sink into
Its consciousness, how long for the speed of light to change?

In 1912, Alfred Wegener proposed that the continents have been slowly drifting about the globe. #Poetry #Science #History #Geophysics #ContinentalDrift #Wegener (https://sharpgiving.com/thebookofscience/items/p1912.html)

Episode 2.8 is now available on #YouTube!

Have you ever thought about how dinosaurs lived on a warm, swampy Earth and how we live on one that’s cold enough to keep pretty much the entirety of Greenland and Antarctica buried under kilometers-thick sheets of solid ice and wondered, hmm, how did we get from there to here? The short answer is that it took 50 million years of declining atmospheric carbon dioxide concentrations and dropping temperatures, not to mention building an ice sheet or two. For the longer story of the last 50 million years of climate change, including some of the reasons why, catch this episode of our podcast with Dr De La Rocha! You’ll hear about plate tectonics and continental drift, silicate weathering, carbonate sedimentation, and the spectacular effects the growth of Earth’s ice sheets have had on Earth’s climate. There are also lessons here for where anthropogenic global warming is going and whether or not its effects have permanently disrupted the climate system. Fun fact: the total amount of climate change between 50 million years ago and now dwarfs what we’re driving by burning fossil fuels, and yet, what we’re doing is more terrifying, in that it’s unfolding millions of times faster.

Betsy Mason: Marie Tharp’s groundbreaking maps brought the seafloor to the world: Her deep understanding of geology made for gorgeous and insightful views

"In the middle of the 20th century, when many American scientists were in revolt against continental drift — the controversial idea that the continents are not fixed in place — Tharp’s groundbreaking maps helped tilt the scientific view toward acceptance and clear a path for the emerging theory of plate tectonics."

On January 6, 1912, German geologist Alfred Wegener presented his theory of continental drift for the first time in public at a meeting of the Geological Society (‘Geologische Vereinigung’) at Senckenberg Museum in Frankfurt, Germany.

#TodayInHistory German meterologist, geophysicist, Alfred Wegener comes up with his landmark theory of Continental Drift in 1912, where he suggests that all the continents drifted away from one big super continent, gradually.
