If human societies do nothing, in just a few decades, the planet could warm to levels it hasn’t reached in at least 34 million years, leading to more melting glaciers and floods than ever before — as well as the dire effect of urban heat waves.
In 2021, in the U.S. alone, there were already 18 extreme climate-related disasters with losses exceeding $1 billion each, according to the National Oceanic and Atmospheric Administration.
When looking at the world’s natural calamities on a consequence and frequency scale, floods and earthquakes have a more devastating effect on people and property, but they occur less frequently than heat waves, which generally take the form of urban heat islands (UHIs). These are also known as heat pockets, which are found across cities’ downtown areas, where temperatures are higher than the peripheries.
With urbanized areas warming up fast, many more populations globally are bound to face the deadly consequences of the heat-island effect, highlighting urban public health disparities. Between 2000 and 2016, according to the World Health Organization, the number of people exposed to heat waves jumped by 125 million, claiming more than 166,000 lives between 1998 and 2017.
City officials in the U.S. now worry that intense heat could lower comfort levels and conditions for residents, especially the most vulnerable populations — but cities are not equipped with the right data to mitigate effects.
Working at a design-led data science company, I know that building sustainable solutions for organizations or solving complex business, societal and socioeconomic problems can be solved using advanced analytics, artificial intelligence (AI) techniques and interactive data visualizations.
Despite this, these emerging technologies can only be rolled out through collaborations among public health professionals, enterprises, local governments, communities, nonprofits and technology partners. This cross-sector intervention is the only way to democratize technology and rectify the urban heat-island devastation. So, how are these players working together to reduce urban heat islands?
A handful of companies, governments and NGOs across the world are working to solve the problem with heat waves.
However, since Canada warmed by an average of 1.6°C between 1948 and 2012, roughly double the global average rate of warming, it’s way ahead of the game when using AI to predict heat waves. By nature, Canadian cities are technology-driven and tech-savvy, so cities across the world can look to the country for in-depth analysis and innovative ideas. For example, MyHeat tracks the solar potential of buildings, taking the heat wave and using it to create sustainable energy.
European cities, including Helsinki and Amsterdam, are also trying to tackle this challenge. AI4Cities is an EU-funded project bringing together leading European cities looking for AI solutions to accelerate carbon neutrality. The total funding amount of 4.6 million euros will be divided among selected suppliers.
Despite these projects leveraging AI to solve climate change issues, they are still concentrating on other niches, such as reducing carbon footprint. They focus on the mitigation of the cause of climate change instead of the effect.
Therefore, the impact of heat waves remains a largely unsolved problem. This is also because other natural disasters, such as floods that cause huge immediate effects, get more attention. Heat waves are silent killers with their undercurrents of thermal discomfort, more energy usage and power outages. And perhaps the biggest challenge is that the kind of technology to face heat waves is not openly available to municipalities or nonprofits.
Through working with Evergreen, a nonprofit building resilient cities and mitigating climate risks, we were introduced to a network of cities in Canada. And after research and surveys, we realized that there’s a lot of digital infrastructure and data-driven decision-making for floods and earthquakes, but none or very few solutions for heat waves.
Heat waves remain largely an unsolved problem, and there’s a huge opportunity for AI, as a scalable tool, to inform cities to make evidence-based decisions.
Evergreen uses geospatial analytics, AI and big data, alongside a data visualization tool created through the Microsoft AI for Earth grant, to integrate and analyze different datasets that examine urban heat islands across cities. This helps municipalities pinpoint problem areas with low vegetation or impermeable surfaces and mitigate the effects of heat islands by installing cool roofs, water fountains and green roofs.
The AI-powered analysis and visualization tool, built on the Microsoft Azure Stack, offers several capabilities. A map, or a topographic view, allows climate teams in municipalities to get the land surface temperature of every 30-meter block on the ground. Additionally, there’s a Scenario Modeling View that enables them to generate scenarios of the future urban sprawl of cities by modifying features like building counts and height, albedo levels and other urban sprawl parameters.
This multipurpose tool is already impacting climate resilience in municipalities across Canada by tracking greenhouse gases. It could also positively impact policy shifts around greenhouse and carbon dioxide emissions worldwide in years to come.
Sustainable Environment and Ecological Development Society (SEEDS), with Microsoft India, also announced its second phase of an AI model for predicting heat wave risks in India and offering cost-effective interventions. If a heat wave occurs, governments can work out which areas of the city need help and attention. SEEDS uses ground-truth data, and the AI model generates results that are validated on the ground with thermal sensors, among other devices.
City officials should welcome AI as an economical way to face heat wave problems as it is scalable and quickly applicable worldwide — it is agnostic to locality or ground presence. AI can also be packaged into a tool to extract data sources, which makes the knowledge easily shareable across departments and key stakeholders, and digestible for decision-makers.
With Evergreen, the idea is to create a public-facing app, which informs communities about the kind of impact AI has, offering real-life solutions and bringing them alive in a storytelling mode. For example, the app could show how temperatures decreased due to a green roof installation. It would allow users to see data insights as easily consumable stories and help them understand the different complexities that shape the issue they are tackling.
Working with multiple data sources for AI or machine learning (ML) projects calls for cross-sector solutions. The involvement of nonprofits and community builders is crucial — they act as conduits between technology players, enterprises, other nonprofits, governments, communities, city planners, real estate developers and mayors’ offices.
Technology partners cannot just arrive in a city with an AI solution and expect officials to subscribe to it. You have to make a business case and enable all players to be part of the conversation; it is a multisectoral endeavor.
Equally, the stakeholders who would use this innovative technology won’t just automatically adopt this tool if they are told: “You have a heat pocket. I can install a green roof to help you.”
Let’s take a geospatial example, developed in partnership with Microsoft AI for Earth’s initiative. The entire population of a city was mapped — with release points within blocks of 100 square meters in a 40-meter grid — to release genetically modified mosquitoes to kill dangerous, disease-carrying mosquitoes.
This scalable solution with AI can bring resolutions to communities suffering from dengue and yellow fever. But if someone came to your house and said that you would be inundated with...
