Guest Video: The Ocean


I never cared all that much about the ocean until researching the book on how cats evolved. Their story goes back–well, it goes back to the general time of the K/T (K/Pg) extinction if you want to also include the evolution of carnivorans (and I do).

Over the last 66 million years, this planet has had some dramatic changes, and my key to realizing that was this paper. (Don’t feel that you must read that, though the origin story of sequoias is pretty interesting. I’ll include parts of it in the ebook series.)

Think of that as the most basic approach to the ocean and climate – reading what has happened by studying drill cores of abyssal Pacific Ocean mud.

But it’s a good introduction to recent news from the world of science that they have made computer models detailed enough to measure the interaction between ocean eddies and the atmosphere. That’s the ultra-high-definition approach that is shaping meteorology and climate science now and in the immediate future.

Most of us, though, just want a general overview of the ocean and how it affects the planet’s weather and climate.

We move too fast to see much of the movement made by this giant we live on and in, unless it has a spasm of some sort, like an earthquake, eruption, landslide, or storm.

None of us has the time to just stand around, watching the fascinating world around us. Fortunately, there are cameras.

So relax now for 16 minutes or so and let the sky roll over you (watch out for the snails and pity the ants, who live at an even faster pace than our own).



Mr. Tornado: Tetsuya “Ted” Fujita

Tetsuya Fujita is best known for his tornado scale and research into thunderstorms and downbursts. He also did a lot of public outreach and has an IMDb page.

Many of his insights into severe weather came from studying damage patterns. This fascination with damage probably grew out of his early experiences during World War II.

The early years

Fujita was born in 1920 on northern Kyushu Island in the Greater Japanese Empire. His parents, both teachers, lived in a small village. As a child he loved exploring, as well as cartography.

His father died in 1939, two years after the Second Sino-Japanese War had begun. His mother died in 1941, the year that Japan attacked Pearl Harbor.
