The Gulf Stream Explained

Learn about the role of the sea in global warming.

The global conveyer belt is part of the large-scale ocean circulation that is driven by differences in the density of the waters. It plays a key role in keeping the climate at balance and Europe warm. Global warming may change it forever with unforeseeable consequences.

Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking. Because we love science.

We would love to interact more with you, our viewers to figure out what topics you want to see. If you have a suggestion for future videos or feedback, drop us a line! :)

This guy’s voice has not changed in the last 7 years

Is that why Canada, despite being at roughly the same longeitude is colder than Europe?

[JakeBroe]

I'm watching Kurzgesgt's old videos and it is fun to see how much their animation style has improved over the years. But these oldies are still good!

[sylvhide]

That was super useful! Just one thing: 2:26 the salt content doesn't rise by water evaporating (it's way to cold for that) but by water turning into ice which increase the concentration of salt in the water. It also increase in density turning into colder water as explained at the beginning of the video.

0:33 I love how only Canada is whited out, like not Russia or anything, just specifically Canada.

I swear I have learned more from watching youtube that I have ever learned in school.

[AlexJohnson-uegm]

Everybody grab all your salt we're going to Greenland to keep the Gulf Stream goin!

[kukifitte]

It's weird seeing a kurzgesagt video without birds

[kerrychou]

The best and only clear and concise explanation I've seen. So many news outlets talk about gulf stream problems but never explain the link behind it. Thank you

[conors]

Anyone growing up in Europe is taught, formally or informally that the Gulfstream has a massive affect on our lives. Even when you are a very small child. Usually when all the jellyfish start rocking up on shore or hurricanes that never come your way all of a sudden like to glance past. Europe would be nowhere near as green and fertile and moderate compared to other parts of the normal northern hemisphere

So, warming planet leads to ice melt.  Ice melt leads to lower salt levels in the polar oceans.  Lower salt levels leads to a much weaker current that brings warm water/air.  Weaker current leads to lower temperatures.  Lower temperatures leads to ice build up.  Ice build up leads to higher salt levels.  Higher salt levels leads to stronger currents.  Stronger currents lead to higher temperatures.  Higher temperatures leads to more ice melt.  And so on.

I love these Tardis's in every video

[SidV]

So global warming could possibly cause an ice age? Oh the irony...

[sassa]

Coming here after watching Sabine Hossenfelders video. 🙂

[jaredlong]

Wait. Did that thermostat say "DFTBA" on the bottom?

[OneLifeComment]

Legitimately my favourite channel on YouTube now.

[saddish]

watching in August 2018 it shows how much you guys have improved and changed

[Dustfinity]

I would love to watch a remake of this video! longer and covering all the interactions with each current, what theyre called, what causes them, what happens when two meet, etcetc instead of just the gulf stream, even if it has to be cut into multiple parts, its very interesting and there isnt that much information about it, even less laid out in laymans terms, thanks!
