In the US at least, many houses built in the 90s-2000s have mold issues because they were built without proper water vapor permeability and also with materials that are also not moisture resilient. This is even an issue in dry areas like California.

This year seems the worst we've ever seen in our parts of Eastern Australia - we've also had some of the worst ever floods thanks to La Nina (and climate change), so that's more water than ever. And mould being a living thing keeps spreading when not managed, so it's lingering long after the floodwaters receded.

Really starting to feel dangerous to live anywhere in the US southwest. Lake Meade approaching deadpool and massive wildfire nearing my house this summer. Plus the government is led by people who refer to much of the southwest as “fly over country” doesn’t help.

> Plus the government is led by people who refer to much of the southwest as “fly over country” doesn’t help. The people who (you assume) don't use the term "flyover country" are the people stopping Congress from spending money to fix environmental crises like drought. Even so, the White House has ordered studies and gotten Congress to spend a lot of money on the Southwest already[1]. What else are you looking for, e…

Desalinization plants built by California or the Federal Government.

The most important point:

Some researchers argue that the record is simply too sparse to show clearly what is going on, or that there is too much natural variability in the system for researchers to spot long-term trends. But it could also be that the IPCC models are missing something big.

In spite of all the hand-wringing about Global Warming -- which should more accurately be called climate change -- we don't know as much as we so often seem to think we do. The actual data sets don't go back as far as most people imagine and errors in assumptions for models are not uncommon.

> A ‘triple dip’ La Niña — lasting three years in a row — has happened only twice since 1950. Doesn't seem all that rare, then.

2-3 times in a lifetime is rare by some reasonable definition

2 x 3 years would be 6 years. 1950 to 2022 are 72 years. So 6 years of 72 years would be 8,3 percent. YMMV if this can be considered rare

how many states are going to implode, apart from SriLanka? Any guesses?

I currently live just outside of Rocky Mountain National Park and I am not feeling optimistic about the future.

What particularly about Colorado makes you feel not optimistic?

It has increased the frequency of the problem.

Homes tend to stand up to harsh rains, as that is normal. What is not normal is 100 almost consecutive days of the heaviest torrential rain I have every witnessed, similar to a tropical wet season.

With this much rainfall, you get your building tested like never before. Our back lawn was flooded most of the time, with the water seeping into the building whatever way it can. There are new roof leaks, persistent puddles that seep into the brickwork. A stream of water running like a river around the property. High humidity means nothing is drying out. And so on...

It's not really just northern/southern hemisphere. It's also linked to location. Australia gets the opposite weather to South America for the cycle. So for La Nina, it's dry in South America, but wet here in Australia.

In South Africa La Niña is also associated with a wetter season and El Niño with a dryer season.

Didn't that work out in the last 2 cycles of La Niña? I read about drought in South Africa recently but I admittedly know nothing about weather patterns there.

I don't know what news you're plugged in to but I'm not worried at all living in the SW US. Phoenix and Tucson had by far their wettest rainy season in decades last year and are projected to have another wet season this year. And the state of AZ uses less water for 10x the population than it did in the 1950s.

Knowing nothing about Phoenix or Tuscon water management... are there reservoirs for Phoenix or Tuscon that stored this rainfall coming off the local mountains from your wet rainy season? It's hard to untangle where the water comes from, but if not, I'm not sure how it helps.

Also California: "No" to desalination plants: https://www.cnn.com/2022/05/12/us/california-water-desaliniz...

Well that just seems crazy if your state's turning into a desert. What are the arguments against it?

Well it's in the article:

incredible energy consumption, its impacts on marine life, projected sea-level rise and the cost of the resulting water itself -- with that cost being passed on to customers.

[flagged]

I’ve started using it unironically but only after years of that section of a country attacking my part both physically and politically.

It’s flyover country to me because I refuse to give them a dollar in economic activity and will not land in their state. I have spent additional money to take longer flights that put the money into states who do not talk about killing mine.
