Tokyo expands underground 'cathedral' complex to counter climate change rains

An amazing feat of engineering.

“Roaring Fires, Malt Beer, Ripe Meat Off The Bone!”

Looks impressive; that first picture is very ‘Mines of Moria-esque.’

Amazing, but senseless.

Why is this senseless? It seems to me to be an eminently sensible thing to do. Go back a few years and recall what so-called "Superstorm Sandy" did to New York City, flooding subways and tunnels under the Hudson River. New York could have used a similar system to save it from the flooding it experienced.

climate change" rains, really?

Yes. it works two ways. Warmer oceans strengthen over water storms. The strength of a typhoon is determined by sea surface temperature and absence of vertical wind sheer. Warmer oceans equals more intense typhoon.

A warmer atmosphere can hold more moisture. Antarctica is cold and very dry, essentially a desert in terms of annual precipitation, but because it's cold what snow that does fall tends not to melt or sublime, though is is rapidly changing. But a warm atmosphere can hold more water leading to wetter and more intense storms.

They should make a feasibility study if it is possible to use all this stored water to use in a air conditioning system, and/or if it is feasible to generate some electricity. Investing so big amount of money just to collect and through away water does not seem to be the best use of resources, some imagination could be applied to extract some benefits other than avoiding floods.

What else would you call the tropical-like sudden downpours that are happening more and more in the summer season? It's what happens when the ocean gets warmer.

Positive that the government is doing something in advance to at least try to ameliorate the disastrous consequences of climate change, at the end it may not be enough, but every effort is welcomed now that many of those consequences are inevitable. At the very least this shows the science denialism that have taken hold in other places is being ignored in Tokyo.

Agree. It's nice to live somewhere where expertise is generally respected and loudmouth idiots on social media don't get to peddle their propaganda so easily.

The beauty of being a climate zealot is never having to be accountable for their beliefs.

The zealots are the ones that ignore the scientific evidence to feel better about acting irresponsibly. There is zero requirement to stop using technology in order to be ecologically responsible, in the same way that it not necessary to be exercising every hour you are awake in order to have a healthy lifestyle.

Fossil fuels. Best get off them.

Was lucky enough to go on the tour when it was finished.

I feel quite envious. It looks like something from a science fiction movie.

I found a few related videos.

Great videos. Really explains how the system works and its unprecedented size. Thanks.

By chance, the other day I wrote a blog post about the 'cathedral' in relation a visit in August. Here's a link for those who may be interested: https://hoodcp.wordpress.com/2024/09/30/remembering-and-preventing-and-disasters/

This would be a cool place to visit.

So, the system was designed to handle the worst case scenario people saw in 1993.

But it's 2024, once in a thousand years weather keeps happening, so the plan is to expand it.

But imagine if, in 1993, the US (just the US mind you) had reduced per capital fossil fuel usage to the level of France.

That would mean the world would already be on the path to meet the 1.5 degree cap on global warming.

Imagine if China never went down the path of using dirty coal to be the world's manufacturer.

This would be a cool place to visit.

It was a slightly nerdy friend said he had tickets to go down a "storm drain". I nearly didn't go but as I said one of the better experiences in Japan. Much better than the endless reconstructed temples. Seen one, seen them all...

Right.

"As the temperature rises, the amount of water vapor in the atmosphere increases, resulting in relatively larger quantities of rainfall"

The logical conclusion: Curb the temperatue rise.

So the question is to what level of pouring rain will it be upgraded to.

Because one day, you'll have that level surpassed...

All depends what year back to you decide.

In construction, we usually take into account the last hundred years. Because that data is sure and everyone can be accountable for.

What is before is just based on different pieces of evidence and would require hundreds of more billion yens of works.

The cathedral complex..."

"Much better than pouring concrete into the sea (Tetrapod) I suppose...

I would definitely visit this.

Guessing you don't practice what you peach. Would involve turning your phone/computer off for a start.

It's good of them to prepare for the unpredictable. Some years get more rain than others. Floods can happen. This was true fifty, one hundred and a thousand years ago. Still true today. Cool that technology can solve age-old problems.
