Been there done that. 1979.

That's a little snow, not a blizzard...

"The Atacama Desert, the driest and oldest desert on Earth, located in northern Chile, hides a hyper-arid core in which no rain has been recorded during the past 500 years. But this situation has changed in the last three years. For the first time, rainfall has been documented in the hyper-arid core of the Atacama, and contrary to what was expected, the water supply has caused a great devastation among local life. This is the main conclusion of an international study, published today in Scientific Reports titled "Unprecedented rains decimate surface microbial communities in the hyperarid core of the Atacama Desert," directed by researchers from the Center for Astrobiology (CAB). These recent rains are attributed to changing climate over the Pacific Ocean."

Another record breaking rain ...

This wasn't Derna's problem and I hate sharing a Tweet here but I think this user hit the nail on the head with regards to our infrastructure future. We need to vote anyone out of office that prioritizes climate change over health and safety.

As an aside, Tug... 1882, 1903, 2007, 2011, 2021, 2023... The events do appear to be increasing if frequency. It's maybe a sign of bigger things to come? Voting people out of office may not fix it. [ponder]

Yes, that was the point of the tweet. The sewers need to be upgraded. Meanwhile, the politicians want to reverse climate change.
 
Just a caution... upgrading the sewers may not be sufficient.

And here is an example of the fear mongering that will cause mass harm to the human race.
 
Like all good things... we'll have to wait and find out...

New York City, according to a news article, combines sewage and storm runoff into a single system. To the extent that NYC population rises, there is less room in the pipes for the runoff. It was 8.5 million in 2021, 7.8 in 1950, about a 10% increase.

Yes, combined sewers are a big problem in lots of big cities in the US and elsewhere. Lots of them in NYC predate the subway system.
 
Both need to be done.

Upgrade and try and reduce the climate impact others by the time the upgrade is finished it will need done again
 
Ignoring the cost, tearing up 100% of the sewer network sounds like an absolute nightmare to have done even if you had until the end of the century. Here in Sydney they could hardly dig a few centimetres without hitting half a dozen unmapped services per day when they constructed the light rail line a few years back, and that was all surface level.

Why yes, I do in fact have no idea what I'm talking about
 
Lots of work for civil/env and hydrologist engineers on the near horizon! [army]

Someone needs to be working on understanding the interdependence of the gas and electric systems in the face of 11 serious winter storm events having occurred in the last 11 years.

Elliott Report: Complete Electricity Standards, Implement Gas Reliability Rules

From the report..."Nearly 80 percent of the generating units failed to perform at temperatures above their own documented minimum operating temperatures."
 
Right. Not small problems. The bullet points deserve listing. It's a FAIL.

* There were unprecedented unplanned generating unit losses, with nearly 90,000 megawatts out at the same time.

* Nearly 80 percent of the generating units failed to perform at temperatures above their own documented minimum operating temperatures.

* Several electric grid operators had to shed firm load to maintain system reliability.

* Natural gas pipeline pressures dropped largely because of freeze-related production declines in production of Marcellus (23 percent) and Utica (54 percent) shales, as well as other natural gas infrastructure freeze- and equipment-related problems. Every cold weather inquiry report that has studied natural gas production has found cold-related declines in natural gas production, by as much as 70 percent in some cases.

Consolidated Edison Inc., which serves the greater New York Metropolitan area, faced reliability-threatening low pressures on its delivery pipelines, forcing it to declare an emergency and use its own liquefied natural gas facility to maintain service.

I was actually more concerned about failure of AC loads due to heat. Cold can be a real problem, too.

Yup. They're gonna get you one way or another. There are both max and min temperatures to contend with.

The high temperatures finally got me too. Its been 32-34°C (90 to 93 F) here. Today's 34°C broke yesterday's 33, that broke yesterday's 32, which broke the day before's 31° of my 6yrs of records by 6C (11F) and the humidity is pretty high too. So much water around us here that it takes an extra month for summer temperatures to arrive. We'll they did.
