Cities keep being surprised by #climate-aggravated emergencies.
#NewYork was not ready for the #smoke emergency.

"#Wildfire smoke experts said that it would have been difficult to foresee such dramatic impacts but that #ClimateChange is also reshaping natural hazards at a startling pace."

"#Seattle did not have a specific plan for #heatwaves in June 2021, when temperatures soared to 108."

Why New York City was not ready for the air quality crisis

As smoke from the Canadian wildfires rolled over the East coast, New York City officials scrambled to respond as they confronted a lack of preparation for the emergency.

NBC News

The problem with most climate analysis: "#Climate black swans are shot down before they can even take flight."

#BlackSwan events are events that are extremely unlikely but have catastrophic consequences. Models are not good about taking these into account. This is just now starting to be addressed, expect to hear more about "3-sigma" and "5-sigma" events, three to five standard deviations away from the average, meaning statistically extremely unlikely.

We need new tools to predict climate risks

Unprecedented change means we must devise different approaches to complement traditional statistical methods

"As with many recent destructive weather-related events, the flooding of #Montpelier, #Vermont’s capital city, came with little warning."

“I was looking down a storm drain and the water was down there. Then I turned back and it was pouring out,” he said. “Everything in Montpelier got wrecked.”

And more rain is expected for Vermont.

The Guardian

Nobody is prepared for #climate #BlackSwans, and this will cost us, in lives as well as money, and both numbers will be large.

"The rapid onset of consistently hot and deadly temperatures is catching people off guard."

“The human brain can’t keep up with the acceleration and the perception of your own risk.”

‘We are not prepared’: Disasters spread as climate change strikes

The warming planet is causing havoc under the strain from record heat, floods, storms and wildfires. And scientists warn the toll will get worse.

POLITICO

I was going to make a snide remark about humanity facing #ClimateChange like Aethelred the Unready, but then I looked up the English monarch (978-1013).

He wasn't unready.
"The original Old English was un-ræd. This is a pun on Ethelred’s name which means “noble counsel” and un-ræd means “no counsel or ill-advised counsel.” "

https://curioushistorian.com/who-was-ethelred-and-why-was-he-unready

Come to think of it, that IS sort of like "homo sapiens" facing a campaign of climate misinformation.

Who Was Ethelred and Why Was He Unready?

Ethelred II, or Æthelred II if you go by the Old English spelling, was an Anglo-Saxon King of the English from 978 to 1016 a.d.

Curious Historian

#ClimateChange fueled storms are not your grandmothers' storms. In #Chicago, a #BlackSwan in fetid waters.

"Sewage overflows are an indicator that basements are flooding, effectively turning scores of homes into mini stormwater reservoirs.

[Eventually, officials] opened locks near Navy Pier, relieving pressure on the system by allowing more than 1.1 billion gallons of murky, bacteria-laden waste to flow into the region’s chief source of drinking water."

Costly Deep Tunnel flooding project can’t handle Chicago area’s severe storms fueled by climate change

Recent storms suggest rain can now fall so quickly that stormwater tunnels can’t move runoff to McCook Reservoir fast enough to prevent sewage overflows and basement backups.

Chicago Tribune

What we must ditch: complacency.
That tunnel in #Cheongju, #SouthKorea was protected from water by an embankment on the nearby river.

“There did not seem to be particular issues until the breach of the embankment … and due to the rapid influx of water, we did not have enough time to stop the cars from entering.”

That's the kind of #BlackSwan event cities need to explore.

A stitch in time

"Jeong Chang-sam, an engineering professor at Induk University in Seoul specialising in water resources, said #prevention is crucial to minimising damage and the loss of lives, but it is often neglected because the benefits are not immediately obvious to politicians and those in government.

"If you put money into prevention projects, you can do it at half the cost of recovery projects," he said."

South Korea flood deaths cast doubt on work to prepare for extreme weather

A year after South Korea vowed to step up readiness for extreme weather driven by climate change, experts say not enough work has been done even as greater volumes of sudden and torrential rains are expected in coming decades.

Brilliant metaphor by @andrewdessler on how #climate risk is non-linear:

"You go from zero damage if the water stops half an inch below the front door of your house to tens of thousands of dollars of damage if the water rises one additional inch and flows into your house.

The correct mental model for #ClimateChange is that things are fine until they’re not, at which point they’re really terrible. And the system can go from “fine” to “terrible” in the blink of an eye."

@CelloMomOnCars @andrewdessler Reason 57219 why the phrase “climate change” is and always has been weak, ineffective, non-impactful, inaction-generating, and apathy-generating.

It is time to yell “fire” in a crowded planet.
