What rivers can tell us about the earth's history | Liz Hajek

[@Mondope]

The only disappointing part of this was how short it was. Super interesting topic about our home!

[@perspective4738]

I am from Bangladesh and I can relate to the video. Thanks TED for arranging the talk and special thanks to Liz Hajek for the detailed information. (y)

[@jaeayala8616]

Been awhile since I saw a good TED talk. 👍 Love that time lapse of the 🌍. 👍

[@ashleyklatt161]

I just love how Liz didn't infuse politics into her science. Fascinating talk, Liz!

[@daniels.os.]

And that's so bad. She didn't mention politics but what we do with the demographic changes and the geological repercussions it involves, has everything to do with social politics and where taxes are going. Think about it twice little hig school girl.

[@ashleyklatt161]

It isn't her job to study geo-political impacts of rivers moving...she is a geologist, not a political scientist. It is up to someone else to study those things. If you are looking for the geo-political repercussions of rivers moving, this is not the TED talk for you. She is merely discussing the results of her research...not interjecting her own opinions or infusing someone else's research into hers...which is what I find refreshing.

[@daniels.os.]

Stop the bullshit. You're just a teenager that hates to be exposed with the truth of political science. That's all that is happening here and you know it.

very nice and useful presentation , thanks

Finally, back to the science!

[@nikolademitri731]

PSU, nice! I highly regret not going to any of the Ted Talks they hosted, while I was a student. Definitely makes sense that they have this subject material at Penn State, as it's earth sciences/geology department is one of the greatest in the world. I actually took my W course (writing intensive) for experimental designs/methods in the primary earth sciences building there, it was a psychology course, however, strangely enough held in the main Geology floor of that building.. annuyywayyy, great video!

[@daryn3835]

Yay a non-political video. I love science!

[@daniels.os.]

Everything is politics idiot. Since humans gathered in tribal communities... since then... everything a human does is about politics, directly or indirectly. You dummy kid. Go back to school.

[@Happilyperfect]

Hey kid, watch your tone, you are being unreasonably insulting

[@nilsp9426]

Political Science might blow your mind, then ;)

She's so in to it, lovely)

[@Mazurecki56]

I want to be as excited about anything as she is about rocks!

[@iJerrrrrry]

Ah yes. All those geography memories

[@sammyp9514]

fascinating. she would be a great teacher

[@anaghak9852]

very good information. Just one question.. Did we had more rivers earlier than what we have today ? Just wanted to understand if we are moving towards draughts

[@pixiesybil4937]

When she said she´s a geologist, have you also thought about that episode with Sheldon Cooper and the Geology?

[@BathroomCube]

everyone is talking about politics and feminism well i just like seeing someone so passionate about rocks stand up there and nervously talk about their passion for rocks

[@Surgviolinist]

As far as I can remember , kosi river flooding and changing of directions was due to break in some kind of dam in Nepal due to heavy rains ! Had there been no dam , it wouldnt have changed direction ! You ought to put man made things into your observations too

[@brendarua01]

4 Strings Did you watch the whole presentation? She showed a far wider range of time than just that one flood, and this had several course changes, just as big. The movements of the Mississippi are as substantial, both before and after flood control efforts. So your hypothesis is questionable and may need revising. But you are right in general. All inputs should be considered.

[@MikeJones-rk1un]

There were no humans 55 million years ago

[@nres1]

Mike Jones it happen on 2009-2009 not millions years ago- I am from nepal and river koshi over flood diff direction because of dam. Indian government didn’t open the dam fear of Bihar flooding. Hence, river koshi forced to change its course.

[@tomatokyat1580]

It's not south India. It is north India.

[@streamboy15]

Never been this early on a ted talk before

[@nres1]

Love from Nepal.

[@yadaKiKhula]

The Kosi river has a sad history of frequent floods and disrupting lives of thousands.

[@Understanding1]

Good info

[@Monochromicornicopia]

You're probably here for 3:40

[@brendarua01]

This was nicely done, though it only scratches the surface. For example some rivers have built their beds above surrounding ground level. When rivers meander and cut a new path, they can leave the loop behind, entrapped in what some call an Oxbow lake. Most people know the Nile floods to fertilize the surrounding land. But how many know that a major source of forest food is salmon who die, decompose and get distributed by flooding. You might thank salmon for your house!

[@AbooRasta]

Hey I have a question, I wonder if anyone could help and refernce me to some material on the subjec. At around 8:30 minutes in she speaks about a time when the earth's poles had palm trees. And that's everything anyone ever mentions about this period - The tropical poles. My question is how did the rest of the earth look at that time? Was the equator and everything north and south of it for thosands of kms a huge desert? Did anything manage to live there? What were the conditions there? Etc... Thanks ahead to anyone that could help I've been thinking about this for a long time now and it would really help me progress with some project I'm working on ☺

[@Skillseboy1]

I liked this talk was pure science but the talk itself was pretty badly constructed. Liz makes points like: "It's important we know how these landscapes will change." But nowhere in the video she actually explains why. I feel this talk had little structure where there is no real direction.

[@MikeJones-rk1un]

Rob: You should have learned about erosion in third grade.

[@Skillseboy1]

Mike M What makes you think I didn't? How is this relevant to my comment?

[@neeraj21489]

True, very inconclusive talk I feel!

[@ApplesThatRead]

She made a clear point about why it is important we know why these landscapes work. She explains clearly that communities often are built around major water ways and cites an example of a river abruptly changing position ~30 milies in a time span of 2 weeks. That's entire homes and communities potentially destroyed by flooding. Prior to the statement she explained exactly why it is important to undertsnad how landscapes dominated by fluvial systems will change.

We don't know,,, is the real honest answer. But a good story will make a believe that its just like another honest lie.

[@PoeCompany]

This is all common sense. Nothing on this earth is Static. If you didn't know any of this before this video then you didn't pay attention in school.

[@xl000]

Is it true that it smells like death in Indian cities ?

[@whuzzzup]

Nice talk. No SJW or social bullshit.

[@TimmacTR]

No feminism ==> interesting Ted Talk... How odd! I would have never imagined that! xDD

[@daniels.os.]

She is a product of second wave feminism battle for women's right for going to universities you dummy. Each time you see a successful women in academy, you should thank historic feminism. Damn, ted watchers are such low iq common sense resentful kids. Lol.
