"The 21st Century Question: Emergently Engineering the Future"

Follow this 🧵 today and tomorrow for highlights from our 2022 #AppliedComplexity Network and Board of Trustees Symposium:

santafe.edu/events/annual-…

#Web3 #Cities #Polarization #EmergentEngineering #Decentralization

We start with a talk by SFI President David Krakauer:

"Would anyone care to guess why we're so GOOD at building transistors and so CRAP at designing drugs?"

"This thing [points to transistor] lives in a centralized system. This thing [points to cancer drug] lives in US."

"I'm going to pick on economics, because we like to do that at SFI. 'Ooh, look at that cover! So techy. Global, heat maps...' But here's 'Networks' [in the textbook]. THAT'S IT. Here's '#ComplexityEconomics.' NOTHING."

@USAS_WW1

#NEOM aka “#TheLine”, #SaudiArabia will take 10 years to build, 105-mile-long linear city for 9 million people. No cars. Super-high-speed train to connect end-to-end in 20 minutes. Mirrored exterior. 500 meters tall. My thoughts follow... #Future

2/ #CitiesSkylines #STEM Don't get me wrong. I love technology and was fascinated by giant space stations in the sky as a kid. But... The first problem I see is there's no existing anchor town or organic reason for #NEOM to exist where it is to be built.

3/ #Ghosts People don't like moving 1,000 miles to an empty city where there is no one and especially no one they already know. The city is actually a series of modules / mini-cities. I'd build one of these around a metro stop in Riyadh and see if anyone moves in.

Ring roads as a ‘spatial imaginary’ has been quite a hit around the world. Most large cities around the world have one.

Bypasses around many large and small towns were built in many areas when many old roads were upgraded to four-lane status in the 1930s to 1950s, leaving the old road in place to serve the town or city, but allowing through travelers to continue on a wider and faster route.

Construction of fully circumferential ring roads has generally occurred more recently, beginning in the 1960s in many areas, when the U.S. Interstate Highway System and similar-quality roads elsewhere were designed.

Although future #warming will affect #vegetation, the big draw of this paper is the specific impact on #urban #forests. However, I would take quantitative estimates made with these #models with a grain of salt since they don't provide "true" urban climate signals. [1/n]

https://twitter.com/NaturePortfolio/status/1571948494218199043

The study uses projections from 10 Global Climate Models (#GCMs) over 164 #cities; comparing modeled variables relevant to species survival against baseline values to predict future risk. A big issue is that most of these GCMs do not represent cities in any meaningful way. [2/n]

Several of the GCMs do not have explicit urban land cover or use simplified slab models. The former provides no urban-specific signals and the latter overestimates urban warming. More importantly, around half of the models use versions of the Community Land Model (CLM). [3/n]

1/n

❓ Why are we focusing on cities?

By 2050, almost 68% of the world's population will be living in cities and breathing urban air. And #cities are already at the front line for air pollution impacts- and interventions.

#CleanAirForAll #AirQuality

2/n

Residents in #cities are often exposed to poor #AirQuality.

#DYK that around the world, a majority of cities do not meet the WHO Guideline for NO2?

Embedding gender considerations and facilitating #women’s participation in project design and implementation along with #inclusive #policies, training, information access, planning, and monitoring is needed

Additional course correction for #SDG5 is needed.
Our #SDG5plus (SDG5+) approach takes into consideration #intersectionality and gender aspects beyond #women alone, & can help #adaptation actions move towards meeting #genderequality and other #climatejustice goals.

EnR - European Energy Network

@EnR_Network

The @EnR_Network held its first in person meeting in over 2 years in #Lisbon. After a first day of fruitful discussion on collaborative action between Energy Agencies, today, the network held a seminar on #energy and #water #efficiency at national and local levels.

The President of @EnR_Network, @nelsonlage highlighted the role of energy agencies in the #GreenTransition, as enabling agents acting between international and local level, to balance the three dimensions of the #EnergyTrilemma: Security Affordability #Sustainability

Sec of State @Joaogalamba described the vision for national-local level governance towards #NetZero in 2050: "energy agencies work to mobilize local authorities, economic players, and citizens to fight #ClimateCrisis, to foster cities’ pivotal role to deliver the #EUGreenDeal"

Current research on microplastics is the stuff of nightmares-

They’re dangerous, they’re spread through our food, they're in the air... they’re everywhere

Thread 1/x
#health #ClimateCrisis #PlasticPollution #food

Much of the research is trapped behind paywalls, and only reported on in a limited, fragmented pattern

-like so much else when large corporations cause environmental damage and impose widespread health impacts on the public

2/x
#health #ClimateCrisis #PlasticPollution #food

The growing risks of microplastics are a direct function of an ongoing push by the same sociopathic corporations that are driving the climate crisis

@marielvilella

These are our 5 takeaways from the #IPCC report on #mitigation, looking at what it means for the #waste sector. Spoiler: we need to cut emissions as fast and furious as we can, and reducing #waste, #plastic and being more materials efficient can help lots
no-burn.org/ipcc-takeaways…

As the report points out, the #waste sector remains the largest contributor to urban emissions after the energy sector, even in low-carbon #cities. Urban areas themselves represent the lion’s share of global emissions, and it's increasing: from 60% in 2000 to 67% in 2015.

So, the @IPCC_CH #ClimateReport recognises that cities can significantly reduce emissions, but this requires systemic transformation: #circulareconomy, #inclusion, #equity, innovative technologies can make a huge contribution towards low carbon urban devel'mnt

What are the #climatechange impacts and opportunities in #cities? IPCC report too long? Here are 15 Key Takeaways (mostly) from the Urban chapter (Ch6) from the @IPCC_CH AR6 WGII Climate Report 2022. Unroll thread below:

Built on work of amazing people @dee_are_dee @BMHayward Mark Pelling @VaneBailo @EricChu @AnjalPrakash @GinaZiervogel @Luna_Khirfan Eric Chu Yan Zheng and more

1. Climate change is a threat multiplier: Climate hazards interact with urban development to drive vulnerability and risks in cities. Impacts and risks likely to increase for the next two decades and risks from 2050 onwards could be severe if warming is not limited to 1.5°C.

1/n 📢🧵: The @IPCC_CH launched their new report (WG2-AR6) this week, exploring the impacts of #climate risks, #adaptation & vulnerability. Here are some insights on the key takeaways for #India.🇮🇳🌏♻️
#ClimateReport #IPCC #IPCCReport
🔗Read Asia Ch. 10 ➡️ bit.ly/3twyIVI

2/n #India🇮🇳 is at risk of multiple #climaticrisks, many of which are accelerating in frequency & intensity. Rising temp.🌡️are likely to cause severe heat stress in summer, esp. in cities where temp.🌡️can be more than 2℃ warmer than the surroundings due to heat island effects.

3/n Extreme rainfall events are projected to lead to more frequent #flooding in settlements near vulnerable rivers & flood risks across the country will become more frequent & severe. Higher than 🌏 mean sea level rise for #Asia’s coasts exposes 🇮🇳’s large coastal population.

++ NEW working paper is OUT ++
un lavoro dedicato ai trasporti pubblici locali (TPL) e a Roma🚈

In questo lavoro analizziamo l’impatto della realizzazione della linea C della metropolitana di Roma sul mercato immobiliare e sull’attività economica locale

un thread 👇🧵 1/N

Inaugurata tra 2014 e 2018 dopo una lunga gestazione, la metro C si snoda per 18,1km ed è la 3a metro di Roma, cui spetta la maglia nera del TPL tra le capitali europee, con soli 1,35km di linee metropolitane ogni 100.000 abitanti, contro i 2,96 di Milano o i 3,87 di Londra 2/N

Se rapportati ai 41,3km di linee preesistenti, la metro C ha rappresentato un’importante innovazione nell’ambito del TPL romano. Ciononostante il suo impatto sul tessuto economico della città e soprattutto sul mercato immobiliare rimane inesplorato 3/N

@InnovateEconomy

#NEW: The first economic impact analysis of the largest remote worker incentive program, @tulsaremote.

The first cohort of members will contribute $62 mil. in new local earnings in 2021—a near-14x return for each $1 spent on the incentive 🧵⬇️
eig.org/tulsa-remote

.@tulsaremote offers $10K to eligible remote workers who move to Tulsa to live and work for at least one year.
- Over 1,200 will have moved to the city by year’s end
- Avg. income of program members = $104,600
- 88% of program members have at least a bachelor’s degree

EIG's analysis found that Tulsa Remote is already generating observable impacts on the local economy:
- For every $1 spent toward relocating a remote worker, there was a $13.77 boost in new local earnings
- Approx. 1 new job was created for every 2 remote workers who relocated
