Top Comments of this video!! :3
After Hurricane Katrina in New Orleans, the government was studying flood & storm surge damage. They brought in experts from Northern Europe. They recommended building canals through housing neighborhoods, instead of big lakes & dams. The locals said the canals would be unsafe for children, and wondered by they work in Europe. The answer was āwe teach our children to swim.ā The suggested improvements were never built.

I think one of the main reasons for the South Carolina floods was the absolute firehose of rain coming in from the Atlantic. The rising levels in Lake Murray required all six floodgates on the dam to be opened to avoid an overflow; the increase in water flow broke 2 more dams further down the Saluda River. (The area near where I live was under 7 feet of water). This begs the question, is the actual weather affected by the nodal cycles or just the tides? Most people think the floods were just part of a particularly unusual weather event.

The water is trying to fling off into space due to its somewhat linear momentum in a lower gravitational position. Spinning is an effect that increases towards the equator and has nothing to do with affecting lunar tides. If the Earth weren't spinning you would still get the same tidal effect. The spin effect is completely separate.

4:40 Spring tides happen twice a lunar month "not 6 to 8 times a year". I think you might mean "king tides" in this instance.
The spinning dancers explanation of the 2nd high tide opposite the moon is just brilliant. I have been trying to visualise how that opposite side bulge occurs for a long time. This really explains the mechanism for me. So simple. Thanks!

I'm not so sure climate change is going to cause so much sea level rise to makes this worse than normal. 20 years ago they said Miami would be under water 10 years ago and the ocean is still no where any kind of description of NEAR putting south Florida in the under water. I have a feeling some high tides will truly be the least of anyone's problems in 2034.

Another interesting facet of orbital dynamics! Thanks!
I was slightly disappointed with the simplified and erroneous tidal forces explanation for the two bulges caused by tidal effects of the Moon and Sun. The reason for the bulge on the opposing side from the Moon or Sun is not due to centrifugal forces of the spinning Earth. (If this were the case we'd truly be screwed!) The distance differential and thus gravitational forces on the distant side of an orbiting object is less and thus a spherical object will flatten.

Every time I hear about threats to low-lying coastal areas, I think about all the low-lying areas that have been consumed by the seas in recent decades - and then I remember that weren't any and that (for instance) The Maldives are still there and not only that, but so many global powerbrokers have high-value properties right by allegedly threatened coastlines.

Hi! I'm a uni student who's currently in a restoration ecology class. I'm going to strongly disagree with your point about the Netherlands. Those pump and levee systems are rather fragile, because they need really high levees in order to keep the water out, and constant maintenance to keep them functioning. Where these systems are built, they destroy native habitat that is just as much of a carbon sink as the mangroves you mentioned. They also prevent silt deposition to the coastline from the channelized rivers, which makes the coastline more vulnerable to erosion. It is not a long term solution, as ocean water levels will continue to rise and more money will be needed to put together even more aggressive pump/levee systems. A better "working with nature" approach would be to put everything on stilts, and not completely destroy the habitat that everything is built on. That isn't particularly appealing or functional for our current way of life, so the real best alternative is to move away from the coastlines and onto higher ground.

The stuff about the Moon and its impact on Earth is really cool, especially the Lunar Nodal Cycle. I never realized how much the Moon, Earth, and Sun work together to create big tides and even floods. Itās like everything in space is connected in this delicate way, and what happens way out there actually affects us here. Itās pretty wild to think about!
(EDIT): The fact that I took a youtube transcript of this video; fed it to chatGPT and told it to make a comment that makes me look stupid at the same time as it seems like I payed attention to the video to make people argue Just shows how dangerous AI can be. keep your eyes peeled :)

You guys have really been enjoying learning about the cycles affecting the Earth, and this was the last one in this series in production. If you want to see the other videos I've done on this series, check out this playlist: https://www.youtube.com/watch?v=mggRl80WzbE&list=PL2gLpWRK0QlBWT8Pe79Ydegw1Hk8Yw6r6 Have I missed any cycles out, or is there something you want to learn more about? Let me know.
