Wildfires are increasing in severity with drought. California began 2025 with a conflagration in the Los Angeles area accelerated by high winds. In 2024, across the United States, over 61,000 fires burned more than 8,000,000 acres.

Globally, wildfires observed by the Copernicus Atmosphere Monitoring Service (CAMS) not only destroyed land, particularly in North and South America, but emitted 1,940 megatonnes of carbon monoxide, and deadly particulate matter. While the first response to a wildfire is saving lives, and then homes and businesses, the impact on air pollution is also an important factor.

With climate change, planetary warming, and increasing drought, fires will be a problem well into the future. What are some ways we can defend and protect against wildfires?

Xeriscaping saves water and stops fire. Image: “Los Angeles Air Force Base xeriscaping” by AF_SMC, 2015. Public Domain.

Defensible Space: our modern day lawns are the result of medieval fire defense. Castles were surrounded by fields: in order to spot encroaching enemies who might attack or set fire to grasses and plants, lords of the manor required areas around the castle be scythed. Cut grass became an upper class symbol that gave us modern day lawns. But according to FEMA guidelines for wildland/urban interface construction, defensible space can be improved. Southern Nevada Water Authority recently passed the first ever permanent law against “non-functional turf” – no more lawns after 2027. Landscaping designers might offer xeriscaping, saving water and protecting against fire.

Housing Shortages and Urban Expansion: California leads the Western United States in building in locations with high risk for fire, but Utah is second, followed by Colorado and Arizona. Wildland/Urban Interface is the term: California is an example, building 10,000 homes in the last decade in areas prone to wildfire. Urban sprawl also leads to traffic congestion as workers commute into the city from far-flung locations in order to afford housing. Solutions to housing must be part of future municipal planning, particularly when new housing areas are developed in fire or flood zones.

Water Infrastructure: In times of drought, water scarcity can lead to difficult decisions about how to allocate water. California’s residential population uses only 10% of the state’s water: agriculture drains far more. Should crops like almonds that require large amounts of water be subject to special taxing?

Insurance: An estimated 16,500 properties have been lost so far, in the Palisades and Eaton fires that consumed 38,000 acres to date: the Kenneth and Hurst fires are yet to be tallied. The Insurance Information Institute reported some companies had stopped issuing new homeowner policies, responding to a California requirement that insurance companies must hold certain reserves. University of California Berkeley’s Center for Law, Energy, and the Environment observed that profitability for existing companies will be severely restricted. Some homeowners resorted to California’s FAIR plan, insurer of last resort, but even that resource is now threatened. Globally, the insurance industry is increasingly denying payouts for rebuilding in zones with repeated losses.

Building Materials: wood has been a preferred material for structures because of its strength and availability. But the history of London Bridge might send a warning: the span was crossed by timbers during Roman times. But in 1176 King Henry II selected Peter de Colechurch to construct, next to the existing wooden span, a stone bridge. London Bridge burned again in 1632. Today, roof coverings, siding, decks, and houses should be built with noncombustible or fire-resistant materials. Windows and attic vents pose vulnerabilities unless specifically protected, because once breached, these apertures can allow fire to enter a dwelling. Top five fire-resistant building materials are: fire-resistant glass for windows; concrete for structures, especially new formulations of Insulating Concrete Form (ICF); stucco made of Portland cement, sand, and lime; gypsum board for drywall; and brick or stone.

Nikola Telsa was there first; Peter Glaser, next. Telsa was sending wireless power from Niagara Falls; Glaser, from space to earth. Now, technology might free your mobile phone from battery recharging when you are in a wi-fi zone. And the walls of your office or school could tell a tale or two.

It’s more than just a personal device. The rectenna converts AC electromagnetic waves into DC electricity. New MIT-designed rectennae could stretch across highways or bridges, making it possible to report all manner of developments while recharging an array of options. The technology, developed by Professor Tomás Palacios of MIT/MTL Center for Graphene Devices and 2D Systems in the Microsystems Technology Laboratories (MIT-CG), might extend the internet of things. Partners in the project include Technical University of Madrid, Boston University, and other institutions and research labs.

Another application? A medical device you may happen to wear like an insulin pump, watchman, or pacemaker, or even a diagnostic “pill or capsule” that patients swallow to circulate internally and report data. Such pills cannot be powered by batteries lest lithium might leak toxins. Developments at MIT’s Medical Electronic Device Realization Center (MEDRC) may advance the information-driven healthcare sector.

At the beach? Visit the coffee kiosk where wifi might charge your phone. Even whole cities are going live: Philadelphia declared it would be the first municipal wifi network in 2004: the vision is still to be completed. Offices have wifi; so do airports, hospital lobbies, schools. It’s a two-way proposition: charging and also data-collecting. Now, wi-fi harvesting devices could give new meaning to the phrase: “If walls could talk.”

CITIES: Labor Day – Unions and Collective Voice

Posted on September 2, 2024September 3, 2024 by Building The World

Labor Day is celebrated in Canada and the US on the first Monday of September. The holiday’s history is one of unions and collective voice. Image: Paramount Pictures, 2014. Public Domain.

SEPTEMBER LABOR DAY – Observed in Canada and the US, honors workers and their rights including the right to organize. Those rights were born and nurtured in the nest of cities.

GUILDS, UNIONS, ILO – Unions go back to medieval times. When the feudal system changed to free independent skilled labor, craft workers moved to cities and banded together to form guilds. But when outsiders, non-guild members or not even industry professionals, began to own the companies that hired the workers, unions developed. (Brentano)

The inclusive, and protective spirit of the guilds, and unions, may today be kept in the International Labour Organization (ILO). Founded in 1919 to bring together governments, employers, and workers of the Member States of the United Nations (ILO is its only tripartite agency), the ILO seeks to promote social dialogue among all three, with special attention to Sustainable Development Goals (specifically: SDG 8 regarding work and growth, SDG 10 reducing inequalities, and SDG for justice and peace).

Workers’ hours have been a constant theme in unions, labor, and rights. Image: “Animated clock” by Balti sahib, Creative Commons 3.0.

HOURS – With unions came working conditions. Work days could last as long as 10 hours, and the work week could be six days, until 1593 when Spain became the first nation to declare a law to limit factory and building workers to an eight-hour day. The Ordenanzas de Felipe II included an interesting aspect that applies to today’s emerging worker rights law: a mandatory break between morning and afternoon work periods was ordered – to avoid the sun’s heat. In the 19th century, Robert Owen proposed a day sectioned into three parts: eight hours of labor; eight hours of recreation eight hours of rest. The movement reached farther shores when stone mason workers marched from Australia’s University of Melbourne to Parliament in Australia to establish the law.

Both Peter and Matthew McGuire both advocated the establishment of a holiday to honor the craft and skill of workers. The first Labor Day celebration took place in New York City in 1882: both McGuires were present. Image: Maguire (McGuire) family crest, Creative Commons 3.0.

CRAFT AND SKILL – In the United States, the first proposed Labor Day holiday originally honored labor as art and the skills of craft. Peter J. McGuire, general secretary of the Brotherhood (a guild name that needed updating) of Carpenters and Joiners who was also the co-founder of the American Federation of Labor. McGuire proposed the idea of establishing a holiday to honor “those who from rude nature have delved and carved all the grandeur we behold.” (US Department of Labor 2024)

A second McGuire – Matthew – is also credited for the holiday. This McGuire, secretary of Local 344 of the International Association of Machinists, also proposed the holiday in 1882 while serving as secretary of the Central Labor Union of New York. A first Labor Day gathering convened in New York City in 1882: both McGuires were present. A second observation happened in 1883. In 1884, President Cleveland signed a law creating a national holiday to be called Labor Day, to be observed on the first Monday of the month of September annually.

RIGHTS – But in a twist of fate, President Cleveland signed that law in July 1884, just before an uprising of labor caused a national tragedy and forever changed the character of Labor Day. Worker rights for hours and working conditions arose in Chicago, Illinois on several pivotal moments. One involved the transport industry and the innovation of transcontinental rail. Chicago was a known rail center, and headquarters of the Pullman company. The cross-country rail industry created a market for overnight travel. Chicago’s Pullman company (formed by buying up old passenger rail cars and turning them into sleepers) employed “Pullman porters;” hiring practice discriminated racially and enforced extremely long working hour – 400 per month. At the trigger of the 30% layoff, and to protest working conditions and assert worker rights, Pullman workers walked out on strike.

Transcontinental rail established a new order, one that could be disrupted by striking workers with new power. Image: Map showing section of Transcontinental Railroad, 1883. Atlantic and Pacific Railroad, Chicago and Pacific Railroad, C.W. & C. Colton & Company, US Library of Congress. Public Domain.

STRIKE POWER – Travel stalled in 27 states from Chicago’s Illinois to the West Coast. Communications stalled across the country: at that time, trains carried not only cargo and people but the post including commercial transactions. Strikers knew well how to stop a rail car on the line; they halted – and derailed – the locomotive pulling a postal train. The collective voice was heard. But so were gunshots.

Pullman strike erupted into violence; workers overturned rail cars and Illinois National Guard fired shots. Illustration by G. W. Peters, *Harper’s Weekly*, Volume 38, 1894. Public domain.

VIOLENCE – With the country effectively shut down, President Grover Cleveland authorized the US Attorney General to enact an injunction against the striking workers. The result was an acceleration of the strike into a riot. Protesters derailed more train cars. Escalation into military action ensued when the Illinois National Guard arrived at Blue Island, a Chicago suburb, and used firearms, killing 30 people and wounding many others. This happened in July. Ironically, President Cleveland had just signed the bill, in June, declaring a new holiday to honor workers.

Haymarket Square, Chicago, circa 1905. Image from postcard. Public domain.

In 1886, Chicago again was the center for a gathering to promote the eight-hour work day, overtime pay, and fair hiring practices. Child labor was reported in some areas. Workers went on strike at the McCormick Harvesting Machine Company. Police were present, and one person was killed and others wounded when police opened fire. The next day, protestors assembled in Haymarket Square. Police were again present. Someone, it is still unknown who, threw a bomb; police began shooting. Seven officers died, several civilians, and many dozen people were wounded. The episode became known in the history of labor as the Haymarket Massacre or the Haymarket Affair. A campaign to find the bomber resulted in hunt for perpetrators and later in several hangings, one suicide, one prison sentence and a later pardon.

UNIONS AND PEACE – In ancient times, the Netherlands organized climate response unions to gather if a dike overflowed. Today, a proposed Climate Conservation Corps could involve unions in the shared effort that all professions must contribute to our common future. The voices of unions as part of the International Labour Organization might support cooperative vision. Because firearms and violence have been a tragic part of strikes such as Pullman and Haymarket, unions might take up the issue of gun violence. Could unions use their collective voice and global power to unite justice and rights with peace?

Labor binds the world together in a connected, collective system of craft, rights, and honor. Image: Animation by TED-43, 2018. Creative Commons 3.0. With appreciation.

LABOR UNITES THE WORLD – Labor circles and unites the world in a connective, collective system of craft, rights, and honor. This month, in the United States, Labor Day finds 10,000 hotel workers striking to call attention to working hours and conditions. Political candidates and present leaders are appearing and speaking at rallies. The campaign for work and justice will always be new, and needed. Factory workers still labor in unhealthy and even lethal conditions; miners (in some locations, including children) suffer health and injury; health care workers endure long hours. Reparation for enforced labor, in some places continuing, still needs justice. Recently, new regulations on hours of outdoor workers during increased heat of climate change now address worker health, rights, and safety.

If you are reading this in a country that celebrates Labor Day today, make it more than just a long weekend. And, if you live in an area that honors workers at another time, perhaps we can all make September a month when we recognize the farmers whose harvest graces our tables, those workers who create seasonal goods and services, the health care professionals who offer fall influenza protection, the teachers that welcome students for a new year, the transport systems that bring us all to the places where we work and that special place we call home. This month, how will you honor craft, justice, rights – and the fruits of our individual, and collective, labor?

CITIES: Olympian Innovations and Climate Change

Posted on July 26, 2024 by Building The World

“Eiffel Tower” by photographer Tommie Hansen, 2013. Creative Commons 2.0. Included with appreciation.

Paris opens the Olympics today. One hundred years ago, in 1924, the city of lights last hosted the world’s games. What has changed? Each Olympic city endeavors to introduce innovations: this summer, many will reflect responses and solutions to climate change.

Beach volleyball will take place at the foot of the Eiffel Tower ( on a temporary beach of imported sand). Real sand will greet Olympic surfers who will ride the waves in Teahupo’o, Tahiti. For the opening ceremony, athletes will float down the Seine (the city’s mayor swam in the river to prove its cleanliness).

Hosting the Olympics is both a financial danger and an opportunity for upgraded infrastructure. When Tokyo opened the 1964 Olympics, a new transit system debuted. Shinkansen, Japan’s famed train system, was completed just 10 days before. Timing was ideal: the new train line was profitable from day one, according to financial analysis by Japanese historian of technology Hoshimi Uchida. After the Olympics, Shinkansen expanded its reach: in 2022, there were 16,347 miles (27,245 kilometers) of tracks for trains carrying 382 billion passengers.

When Rio de Janeiro hosted the 2016 Olympics, supermodel Gisele Bündchen graced the opening ceremony. Image: Agéncia Brasil, 2016. Creative Commons 3.0. Included with appreciation.

But past performance is not a guarantee of future profits. When Tokyo opened the 2020 Olympics (held in 2021 due to the global pandemic) there were no tourists to ride the rails. Hosting was heroic but unprofitable, costing $20 billion. Athens hosted in 2004, building a stadium that not only racked up debt but, some economists state, may have ushered in a financial meltdown. Rio 2016 featured Gisele Bündchen strolling the opening ceremony to “The Girl from Ipanema.” But the city later had to sell off the newly-built Olympic Village at a financial loss. Looking at the numbers from past Olympics, Denver, Colorado bowed out of the running for the 1976 winter Games. Is hosting the Olympics worth it?

Barcelona emerged, in 1992, as a model of success through Olympian planning. New beaches, new transport including rail and a new airport, new telecommunications systems were so effective that a new term in architecture and urban planning emerged: “the Barcelona Effect.” London’s 2012 Olympics proved a new environmental technology: the renovated West Ham tube station offered renewable electricity created by movement of people crossing floors that lighted the entire metro station. Laurence Kemball-Cook, then a graduate student at Loughborough University, designed the technology plan and later formed PaveGen to offer electric floors to offices, hospitals, schools, and other buildings (including dance clubs) with ample foot traffic.

Dominque Perrault, chief architect for the new Olympian facility at Seine-Saint-Denis, also designed the above pictured Hippodrome de Longchamp in Paris. Image: Madeira78, 2018. Creative Commons 4.0. Included with appreciation.

Will Paris 2024 be a success? Some see renovations in Seine-Saint-Denis – a cluster of 40 small towns – as a means to improve an area plagued by joblessness and crime. After the Games, the area may emerge reborn as a “mixity” of residential and business activity: 40 architects who worked with central planner Dominique Perrault will see if that vision endures. Some worry displaced residents could return only to be priced out. Sustainability is part of the plan: seats for an aquatic center are made from recycled plastic bottle caps collected by children in Seine-Saint-Denis schools. (Kimmelman 2024)

Among the many innovations Paris will bring to the 2024 Olympics is an underground cooling system that will keep athletes comfortable amid the rising heat levels related to climate change. The water-cooled (recycled) technology, part of the Paris vision to be carbon-neutral by 2050, is based on advanced geothermal technology.

CITIES: Fireworks? Or a New Sky!

July 26: the Paris Olympics will feature 10,500 athletes floating along the Seine river in national team boats, with opening ceremony finale at the Trocadéro. Fireworks often illumine Olympic celebrations.

TIME FOR A NEW SKY?

But there are at least two public health reasons why fireworks should no longer be the light show of choice: urban pollution and risk of wildfires. And now, there is a technological opportunity to consider a new sky.

AIR POLLUTION

**Air over cities can improve**. “Fanhe Town, Tieling, China: 10 day interval contrast” by Tomskyhaha, 2019. Included with appreciation.

Air pollution and urban smog are a global problem. But this July, two places may have options for cleaner air. In the USA, many cities suffer air quality issues from ozone with Los Angeles, California the worst, followed by Phoenix, Arizona; Denver, Colorado; Houston, Texas; Las Vegas, Nevada; Chicago, Illinois; and Albuquerque, New Mexico having trouble (descending order). And then there is particulate pollution – deadly to lungs where tiny pieces lodge, causing chronic conditions and also deadly disease. From Bakersfield, Fresno, San Francisco/Oakland, and Los Angeles in California (highest) to Corpus Christi, Texas and Las Vegas, Nevada, the health of urban citizens is at risk.

Paris suffers air quality problems well above World Health Organization recommended limits. Levels of nitrogen dioxide (NO2) and particulate matter have declined since France placed limits on diesel-fueled vehicles, but clouding the skies with explosions, however artistic, stresses the respiratory tracts of viewers, not to mention Earth’s atmosphere. Figures reveal that 7,900 premature deaths could have been avoided in Paris in 2022 if pollution were better controlled. What about 2024?

WILDFIRES

Climate change has brought increasing drought and with it, wildfires. In the United States, California is so prone to wildfires that the state established a tracking dashboard for residents to evaluate daily risk. So far, this summer has seen the Basin fire covering 13,980 acres (26% contained); the Bolt 3-2 fire damaging 10, 353 acres (98% contained). To date, 147,012 acres have burned: up 394%. The site also lists water shortages. Canada also suffered extensive wildfire damage in recent years (see above images from Sentinel-2A).

Did you know that wildfires peak around holidays when local folks set off their own fireworks at their house or area field? According to the US Forest Service, wildfires saw a predictable spike on July 4 during the period of 1992 to 2020. So-called “Roman candles” in Washington, DC burned down a 76-person residential building last week. In 2023, 9,700 people sought hospital emergency treatment for firework-linked injuries: half were children.

A NEW SKY

**Drones offer new sky art**. Image: “Intel Drone 100 Light Show” by Ars Electronica Futurelab, 2015. Photography by Preetam Choudhury, 2015. Creative Commons 4.0. Included with appreciation.

With threats of air pollution and wildfires, some cities are opting out of traditional fireworks and turning to drone sky art. Boulder, Colorado pivoted to drone shows after the Marshall Fire (2021/22) took two lives and 6,000 acres (2,428 hectares). California’s La Jolla and Ocean Beach opted for sky animations six years ago. Napa, a city known for festive toasts, will take precaution in the midst of a dangerous heat wave with attendant fire risks to present July 4th 2024 air choreography by 400 drones. In the UK, at the coronation of King Charles III, the light show was delivered by drones. At the recent Tokyo Olympics, drones ascended to offer sky art.

Drones are becoming a good investment: the market has grown from nil to $1 billion in 2021. Drone stocks are soaring – some as high as the new sky art we may see this July.

CITIES: Labor and Workers’ Rights

Posted on September 4, 2023 by Building The World

Human history may be traced in the move from field to city, from local farm to industrial agriculture, and with that – from indentured field serf to urban worker. Some sociologists say that human history is the history of cities. Cities may also be the birthplace of human, and worker, rights. An example: Wolfsburg, Germany, began as the Duchy of Magdeburg, then became the Stadt des KdF-Wagnes bei Fallersleben (“City of Strength Through Joy at Fallersleben”) as a planned town built to house workers for a factory producing the Volkswagen Beetle car. Volkswagen workers organized labor unions through collective agreements ensuring rights of more than 120,000 workers through the Volkswagen Group Global Works Council (GWC).

“**VW factory, Wolfsburg, Germany**” by photographer HasBS, 2011. Creative Commons 4.0. Included with appreciation.

From the days of Charlemagne and into medieval times, as workers began to move into cities, they organized crafts and trades into guilds. The word “guild” comes from the Anglo-Saxon word “gild” and is related to “geld” meaning money. We still have an echo in today’s word for money in German: Das Geld. In medieval times, each guild member paid a set amount of money into a common fund to support worker training (apprentice, journeyworker, mastercraftsperson) and family benefits for the wellbeing of workers’ health and family support in the case of injury or death. Guilds morphed into trade unions when the owners of businesses changed to outside investors who were not craftpersons themselves. Labor rights were born in the city and have continued to find their growth in urban environments.

**Medieval cities were effectively run by guilds representing all the crafts and trades of the local and regional economy. Guilds set worker rights, wages, and benefits**.

Workers and Rights. Some credit present day labor rights activist Robert Owen, a manufacturer from Wales, with the concept of the eight-hour workday. In 1817, Welsh advocated 8/8/8/ (eight hours labor, eight hours recreation, eight hours rest). Fifty years later, workers in Chicago demanded the Illinois Legislature to pass a law limiting work to eight hours per day. Although the law passed, a loop hole remained and many factory laborers were still overworked and underpaid. On May 1, 1867, they went on strike. The movement shut down Chicago, and soon other cities across the United States and Europe joined the strike. That event in 1867 led to what is now known as May Day or International Workers’ Day.

Labor. Peter McGuire, general secretary of the Brotherhood of Carpenters and Joiners first voiced in 1882 the call for a holiday for “the laboring classes who from rude nature have delved and carved all the grandeur we behold.” McGuire’s message echoed that of the medieval guilds: labor and work are forms of art and should be treasured and honored by a holiday. A leader of a similar surname, Matthew Maguire, secretary of Local 344 of the International Machinists, proposed the same holiday. Their messages were heard.

In the shadow of the Brooklyn Bridge, 10,000 city workers gathered in New York City on 5 September 1882 to rally for improvement in labor conditions. When the American government even began tracking work hours in 1890, the average factory workers clocked in 100 hours per week. Ensuing years strengthened the movement for better working hours and recognition of the major role workers play in business and economics. Oregon was the first state to recognize Labor day but Colorado, Massachusetts, New Jersey, and New York soon joined. In 1894, the Pullman strike in Chicago, Illinois jammed rail traffic throughout the country. During the strike and crisis, President Grover Cleveland signed Labor Day into law, as Congress passed an act declaring a national holiday to honor labor on the first Monday in September. Finally, in 1894, Labor Day became an official national holiday. Canada also celebrates Labor Day, but most of the world honors workers on May 1.

Worker rights continue to be an important issue around the world. In some places, children labor. In other places, women cannot work outside the home. Factory workers are often subject to unhealthy and even lethal conditions: 1500 workers died in preventable factory disasters in the garment industry in fires one decade ago. The 2013 Accord on Fire and Building Safety in Bangladesh made progress in setting new standards; a 2018 Transition Key Accord strengthened the standards to legally binding agreements between trade unions and brands; signatories include an oversight chair from the International Labour Organization (ILO)

Women’s working rights are a special issue. Women make up 70% of the labor force in some export processing zones (EPZs) in Asia, the Americas, and Sub-Saharan Africa where some bans on unionization still exist. The ILO Equal Remuneration Convention (No. 100), Discrimination in Respect of Employment and Occupation (No. 111), and Maternity Protection Convention (No. 183) have helped protect some rights but more is needed. In 1969, the International Labour Organization (ILO) received the Nobel Peace Prize; fifty years later, the ILO issued a new vision when convening the Global Commission on the Future of Work.

Every era brings new challenges for labor, work, and rights. In 2023, the union of Screen Actors Guild and American Federation of Television and Radio Artists (SAG-AFTRA) declared a strike approved by 98% of the members. One concern of the striking union members is the implications of artificial intelligence (AI) and the expansion of streaming services.These artists joined the 11,000 members of the Writers Guild of America who are also on strike. Again, the theme of the guild – and its blend of artistry and rights – finds a place in history.

If you are reading this post in Canada or in the United States, you may be enjoying a day of rest or even a traditional cook-out. But there is more to Labor Day than a long weekend. How will you celebrate and honor worker equality, justice, rights, and the fruits of our individual, and collective, labors?

WATER: Lahaina – Help and Hope

Posted on August 15, 2023 by Building The World

“Lahaina Beach – West Maui” by D. Howard Hitchcock, 1932. Hawaii State Art Museum. Creative Commons 0: public domain. Included with appreciation.

Hawai’i may often be depicted in colors of blue water and green tropical plants. But now, Lahaina, on Maui, is charred brown. Lahaina lost lives: the total of fatalities in the worst fire in US history is still rising, already surpassing deaths in California’s Camp Fire of 2018 that killed 85 people and destroyed the town of Paradise.

“Fire hydrant flushing,” by photographer Lldar Sagdejev, 2011. Creative Commons 4.0. Included with appreciation.

While heat, drought, and wind created conditions for fire, Lahaina’s municipal systems might have made it worse. Hydrants, placed along city streets for emergency water access, produced little to help firefighters. Lahaina’s water infrastructure draws water from a creek and from wells underground. But when the ravaging fire melted delivery pipes, causing them to burst, losing precious water, those leaks, in turn, affected the pressure of the whole water system, including the delivery of water to hydrants.

Fire damage and lost acreage in the U.S. has tripled in the last three decades. Image: “Wildfires burned in the United States” by Our World In Data, 2020. Creative Commons 3.0. Included with appreciation.

As the climate warms, and droughts increase, wildfires may be more frequent. In 2022, seven countries’ capitals surpassed 40-year high temperatures In South Korea, 42,000 acres burned in a fire in Uljin. In Algeria, a fire in the region of Al Taref consumed 14,000 acres. In Argentina, Corrientes province suffered a fire that charred 2, 223, 948 acres.In the USA, the named McKinney Fire burned 60,000 acres. That same year, in the European Union, over 2 million acres burned.

Fire also damages essential infrastructure. Lahaina’s water system suffered damage; that’s not an unusual effect of fire. In Australia, when heat rose to 151 degrees Fahrenheit (66.3 Celsius) and winds gusted to 79 miles per hour (128 kilometers per hour), Snowy Mountains Hydroelectric lost some power when NSW grid links went down; 14,000 people lost electric power. Fire damaging water – the very element needed to quell flames – is not a new phenomenon. In 1633, famous landmark London Bridge suffered a fire that damaged its waterwheels, thereby preventing pumping water to stop the flames. In Lahaina, Hawaiian Electric equipment and infrastructure of Hawaiian Electric, serving 95% of the state’s residents, suffered damage to power lines. With electric and water system affected by the fire, Lahaina’s infrastructure proved to be a factor in the scope of the disaster. An early assessment of the cost of Lahaina fire damage: $6 billion. Lahaina is both a tragedy and a warning.

How can we protect buildings and essential infrastructure? Image: “Fire in Massueville, Quebec, Canada” by photographer Sylvain Pedneault, 2006. Creative Commons 3.0. Included with appreciation.

How can we protect people and property from fires developing from heat, drought, and winds? Here are a few ways:

Assess water systems to protect hydrants and pipes

Climate-proof power grids and essential infrastructure

Limit plants (avoid non-native) and vegetation near buildings

Strengthen regulations for construction materials, emphasizing cement, stone, or stucco

Require tempered glass in windows to reduce window blow-out that fans flames

Test signal systems and err on the side of caution when issuing warnings

It is true that preventive protective measures are costly. But post-fire rebuilding costs are 10 to 50 times suppression costs. Global predictions for climate-related wildfires may reach $50 billion – $100 billion annually by 2050. While the world surely needs to quell warming; meanwhile, directing funds and attention to prevention of future fire damage is important. This will be an area of significant innovation, applicable globally.

Lahaina’s fire was ultimately stopped by water. Flames expired when they had consumed vegetation (some non-native that burned faster) and buildings, until the blaze reached the ocean. People fleeing burning homes endangered their lives to save them by jumping into the Pacific waters. The water system of Lahaina must now be rebuilt. Can the waters of the Pacific help? Maybe. Seawater contains salt, corroding the very means of its conveyance. Moreover, salt water damages vegetation, buildings, and even fire equipment. In the future, desalination innovations may make it possible for coastal areas to use sea water for many purposes, including fire response.

CITIES: HEAT – Below

Posted on August 7, 2023August 6, 2023 by Building The World

**As above, so (much more) below! Cities can be 18F/10C hotter (0r as high as 20C) below, creating underground climate change.** Image: “Morning sunrise above Suwon Gwanggyo Lake with City in Background” by photographer Matthew Schwartz, 2016. Creative Commons 3.0. Included with appreciation.

“As above, so below,” goes the saying. Just one look at a large city’s skyscrapers and buildings will hint at the massive infrastructure below. But did you know that climate change, experienced by the occupants of those buildings, is also lurking beneath their urban landscape? Our cities are suffering under heat domes, but it is even hotter below.

**Machinery under buildings is related to “underground climate change,” a growing urban concern.** Image: “Underfall Yard Pumps” by photographer Blythe Varney, 2017. Creative Commons 4.0. Included with appreciation.

Problem: The technical term is subsurface heat islands, but it’s easier to think of it as underground climate change. Equipment below skyscrapers generates heat; subways and tunnels create conditions that increase warmth. Pipelines under the ground, even sewers, are sources of subsurface heat. Land around and below large structures changes when heated, triggering slight shifts in topography. Foundations begin to erode; tunnels weaken; train rails warp; retaining walls may show cracks, then collapse.

**Subway systems under major cities are one source of underground climate change.** Image: “Washington, DC – Farragut West Station, 2018” by photographer Tdorante10. Creative Commons 4.0. Included with appreciation.

Example: A study by Professor Alessandro F. Rotta Loria of Northwestern University placed sensors under buildings and transport infrastructure in Chicago, Illinois, noting that the ground below was measurably hotter than surface land (a difference of 18F/10C). Professor Rotta Loria studies subsurface urban heat islands, warning that “underground climate change can represent a silent hazard for civil infrastructure…but also an opportunity to reutilize or minimize waste heat in the ground.” (Rotta Loria, 2023).

**Underground climate change can weaken retaining wall**s. Image: “Wallstones Breaking” drawing by Dimitry Borshch, 2008. Creative commons 3.0. Included with appreciation.

Difficulty: Because it is out of sight, underground climate change is difficult to recognize – until a retaining wall breaks. Think of it as similar to the gradual change in an iceberg below the water: slow, relentless, and then tragic. Or a slow earthquake: not sudden – until it is.

**Chicago’s buildings are hotter underground by as much as 18F/10C.** Image: “Chicago Skyline” by photographer Jesse Collins. Creative Commons 3.0. Included with appreciation.

Scale Counts: The bigger the city, the more likely underground climate change is happening. The study cited above was conducted in Chicago: population 2.6 million (2022). The study performed simulations over 100 years: from 1951 when subway tunnels were built under Chicago’s downtown “Loop” to projections until 2051. It is not unique to Chicago. Some of the world’s megacities, with populations over 10 million, could suffer significant damage. Megacities are dense, encouraging high rise construction that may exacerbate underground climate change. Cities that are growing quickly may be particularly vulnerable. For example, the most populous city of Nigeria, and its former capital before the new capital of Abuja was built in 1991, Lagos is among the world’s top ten fastest-growing cities. Another city vulnerable to underground climate change? Tokyo, Japan: population 37 million.

**Dense, populous megacities may be the most vulnerable to underground climate change.** Image: “Oloosa Market in Lagos, Nigeria,” by Omoeko Media, 2018. Creative Commons 4.0. Included with appreciation.

Emerging Answers: There are two approaches – prevent waste heat underground, or use it. In the area of prevention: new urban building codes, especially for dense cities, will need to place more emphasis insulation and energy efficient design. But secondly, waste heat could be used as an energy resource. Geothermal innovations that capture waste heat from the subsurface can find a use for that energy. Innovations for use of waste energy will become an area of significant potential.

Above/Below: We tend to focus on mitigating climate change by addressing what we can see and feel. Noticeable effects are mainly above the ground. But there will also be great need – and opportunity for innovation – below. Is your city likely to experience underground climate change? What are some of the ways your city can measure, assess, plan to address, and even harness for beneficial use, underground climate change?

CITIES: Wildfires, Fireworks, and A New Sky

**Will drones replace fireworks?** Image: Nagaoka Festival 2006 by ZorroIII. Creative Commons 3.0. Included with appreciation.

Many cities light up the sky during festive occasions. In the United States, today marks a holiday often celebrated with fireworks. But with drought plaguing some areas, the risk of igniting wildfires is causing an innovation: sky art with drones. Instead of traditional fireworks, the city of Boulder, Colorado will feature a drone show (the Marshall Fire of 2021/22 killed two people and devastated 6000 acres/2,428 hectares). Galveston, Texas will also illumine the holiday with a drone display. California towns of La Jolla and Ocean Beach will flash the night sky with animations. It’s a new idea for La Jolla: the city has forgone any fireworks for five years.

Drones replacing fireworks on this holiday will not be a first. Tokyo used drones during their most recent Olympics; during their first Olympian experience, the city launched the innovation of Shinkansen. And, in 2023, the coronation of King Charles III featured an artistic drone light display.

**Drones are an innovation that has grown to a $1 billion market in the past decade.** Image: Drone Flying Eye, 2011 by Drone Flying Eye. Creative Commons 3.0. Included with appreciation.

For sky art, drones have advantages over fireworks: no smoke, no falling particles, and a quieter display. Drones are an innovation that has grown impressively over the past ten years from almost nothing to a $1 billion market in 2021.

Has your city used drones instead of fireworks? What do you think of this new trend? For a sample of drone light shows, click here.

CITIES: Wildfires and Climate – How to Help

Posted on June 9, 2023June 9, 2023 by Building The World

Wildfires are increasing due to climate change. Image: “Burning Mangum Fire” in Arizona. Public Domain.Included with appreciation.

June 2023: Canada is on fire (below are links to help). Canadian wildfires have consumed 9.4 million acres (3.9 million hectares) – 15 times the average over the past decade. Quebec fires forced 11,000 residents from their homes; Nova Scotia suffered the largest blaze in its history. The East coast is not alone: Western British Columbia battled the second-biggest wildfire on record for the area. In Central Canada, Alberta issued evacuation orders and heat directives. Canadian railway CN is adjusting trains in several provinces. Why? Drought dries forests and heat sparks blazes. While wildfires are normal in nature, hence the term “wildfire season,” climate change is intensifying the threat to land, cities, and public health.

No longer are fires, and related smoke, a local danger. Just south of Canada, winds blew smoke into the air of Vermont to New York to South Carolina, and then westward to Ohio and Kansas. New York City’s iconic skyline was cloaked in soot. Satellite images show the movement of smoke over Manhattan.

The year 2023’s fire season is just beginning in North America. If recent years are a warning, it is time to take precautions. In 2022, wildfires in California, Oregon, and Washington state consumed thousands of acres, destroyed homes and agricultural land. Canadian British Columbia battled 193 wildfires in 2022, sending smoke to Vancouver and also to Seattle, Washington. Wildfires have become so frequent that they often have names: Sandia, Red, Tower, Mountain, Dixie, Camp. The latter, in 2018, burned 153,000 acres (62,000 hectares), killed 85 people, and destroyed the entire town of Paradise, California.

Camp Fire of 2018 engulfed Paradise. Image: photograph by Landsat and Joshua Stevens, NASA. Public Domain. Included with appreciation.

Wildfires are a global threat. Australia’s wildfires in 2020 spiked atmospheric temperatures and even widened the hole in the ozone layer. Fires threatened Snowy Mountains Hydroelectric‘s largest generator Tumut 3. During China’s 2020 heatwave, the city of Chongqing, home to 32 million people, relocated 1500 residents due to fires erupting. Factories suspended work for seven days. In 2022, Hunan province closed its mountain access for one month to help 4,000 firefighters battle a blaze.

As global space-based observation progresses, we may be able to predict wildfires. The European Forest Fire Information System (EFFIS) reports on European Union countries. EFFIS uses satellites in concert with the Copernicus Atmosphere Monitoring Service (CAMS) to observe active wildfires and estimate air quality pollution. Then, CAMS coordinates with the Global Fire Assimilation System (GFAS) to predict where the wind will blow fire pollution, sending warning to cities. Another space-based monitoring system is CAMS Biomass Burning Aerosol Optical Depth measuring how much sunlight can pass through the air (or not), indicating concentrations of particulate matter.

Particulate matter (PM) is the term for mixture of solid and liquid drops of pollutants suspended and carried in the air. Particles can be made of inorganic and organic compounds including soot, metal, dust, soil, pollen, mold, and little flakes of burnt matter. Small particles can be inhaled, enter the lungs and pass into the bloodstream. The tiniest particles, those less than 2.5 micrometers in diameter and known as PM2.5, are the most dangerous.

How can you tell if your local air’s PM2.5 might be at high levels? Look out any window. If air is hazy, and wind is relatively still, there is danger. Here are actions to take:

Preventing Wild Fires and Related Damage – manage forests, limit residential plantings needing extensive water, build new construction with fire-proof or fire-resistant materials, use satellite data to anticipate fire-prone areas and take preventive action.

Preventing Health Risks due to Fire and Smoke – remain indoors, do not open windows, use an air-filter device if available, cancel unnecessary outdoor exposure. If you do need to venture outdoors, wear an N95 mask (or two), and when returning, remove and launder outerwear garments that may harbor toxic residue.

Providing Help to Those Impacted by Canadian Wildfires – fires have displaced 20,000 people, destroyed property, and sent many to the hospital for smoke inhalation. Here’s some ways to help:

Canadian Red Cross – every dollar donated will be matched;

Firefighters Without Borders – support international and Canadian firefighters;

Donate a Mask – help a charity that distributes free N95 masks.

In the future, climate response will mean addressing, especially, the shared resources of the global commons. These include areas that lie beyond national jurisdiction: the high seas, outer space, and the atmosphere – the very air we breathe. Wildfires may erupt in a specific place, but winds that circle the globe bring “there” to “here.” As we respond to problems we face today, let us keep an eye on a better, cleaner, more equitable future.

But still, like air, I’ll rise. -Maya Angelou
