As California’s climate warms, residents increasingly endure extreme heat events that adversely impact public health. This exacerbates existing risks and will bring new challenges for different regions in the state, threatening the efficacy of traditional intervention strategies. Current thresholds for heat alerts are based on temperatures that exceed historical statistical thresholds, rather than temperatures that cause public health impacts. These ‘health-neutral’ thresholds may underestimate the health risks for the most sensitive populations. The new California Heat Assessment Tool (CHAT) is based on research that establishes local, health-based thresholds for extreme heat that help public officials, health professionals and residents understand what changing conditions mean for them. CHAT is part of California’s Fourth Climate Change Assessment, a state-mandated research program to assess climate change impacts in California, and was developed by Four Twenty Seven, Argos Analytics, the Public Health Institute and Habitat 7 with technical support from the California Department of Public Health.
Explore CHAT at cal-heat.org. This online tool advances the understanding of what types of heat waves pose public health risks and examines how the frequency and severity of local heat waves are expected to change over time due to climate change.

Director of Analytics, Nik Steinberg, discusses wildfire risk, impacts and prevention efforts, on the Midday Briefing. Nik explains implications of increasingly frequent and severe wildfires for the insurance industry and homeowners and shares several ideas for adapting to these risks. While fires have always occurred, climate change is changing the landscape of the wildland-urban interface and residents and policy-makers must understand their wildfire risks and implement preventative strategies. The economic implications are huge for utilities, shareholders and communities, but with intentional planning businesses, governments and residents have the opportunity to mitigate loss.
Climate change will continue to adversely affect public health by threatening sanitation, altering the distribution of vector-borne disease, increasing the need for effective heat wave responses, introducing new mental health challenges and more. To help cities understand their vulnerability to these impacts and build resilience, the United Nations Office for Disaster Risk Reduction (UNISDR) developed a Public Health System Resilience Addendum for its Disaster Resilience Scorecard for cities.
The addendum includes 24 questions, defining a 0-5 scale for practitioners to quantify their responses (see example below). The questions cover the integration of public health with each of UNISDR’s Ten Essentials for Making Cities Resilient: disaster governance, disaster scenarios, finances, land use and building codes, ecosystem services, institutional capacity, societal capacity, infrastructure resilience, disaster response, and disaster recovery.
By capturing all of the possible weak spots in the broader health system, the addendum is meant to be a tool for mainstreaming public health considerations into disaster risk reduction plans, rather than just serving as a one-time assessment. Using this integrated approach can help city officials build resilience over time. Recent events like the power outage that led to eight deaths in a Florida nursing home after Hurricane Irma demonstrate the preventable nature of many public health disasters. Ensuring that critical facilities have backup power supplies and that potential hazards are effectively communicated are ways in which effective planning can mitigate loss. By understanding existing vulnerabilities and how these will worsen with climate change, officials can implement essential adaptation measures that will save lives.
Four Twenty Seven contributed to this addendum and has developed a methodology to assess climate risk exposure in U.S. cities and counties. We are continuing research on quantifying local resilience to climate impacts and supporting public health responses to climate change. The forthcoming California Heat Assessment Tool will provide public health officials with an interactive platform to understand the projected increase in extreme heat events in each California census tract, based on the sensitivity of the local populations. It will also show the distribution of frontline individuals, such as the elderly, to inform effective local heat responses. This free, user-friendly tool will be live in mid-August.
This Four Twenty Seven webinar familiarizes participants with an approach for assessing city-level physical climate risks and provides insight into concrete actions that cities can take to more effectively attract investor financing for climate adaptation and resilience.

Chief Development Officer, Frank Freitas, discusses Four Twenty Seven’s report on Assessing Exposure to Climate Risk in U.S. Municipalities on the Midday Briefing. During this brief interview Frank describes Four Twenty Seven’s work as a data provider for investors, highlights the ubiquity of climate hazards across United States munies and explains the impact of both acute events like hurricanes and more subtlety destructive chronic stresses such as drought.
Events once considered “hundred year” disasters increasingly occur several times in individual lifetimes. In the face of urgent crisis, community leaders, businesses, nonprofits and individuals have seen a need to build resilience, to preserve human lives and the economies upon which they depend. Recognizing the emergence of a field of climate adaptation and seeking details on the field’s development, potential and challenges, the Kresge Foundation commissioned an assessment of the field of adaptation. This project culminated in a report, Rising to the Challenge, Together: A Review and Critical Assessment of the State of the US Climate Adaptation Field, by Susanne C. Moser of Susanne Moser Research and Consulting, Joyce Coffee of Climate Resilience Solutions, and Aleka Seville, Four Twenty Seven’s Director of Community Adaptation at the time. Read the full press release below:
The emerging field of climate adaptation is growing in sophistication and influence, but there is a significant gap between the magnitude of the challenge and existing efforts to protect people and property from climate volatility, according to a report released today.
“Rising to the Challenge, Together” provides a critical assessment of the state of the climate adaptation field in the U.S. It was commissioned by The Kresge Foundation and authored by a trio of adaptation experts: Susanne C. Moser of Susanne Moser Research and Consulting; Joyce Coffee of Climate Resilience Consulting; and Aleka Seville of Four Twenty Seven, Inc.
The report finds that the challenge of climate adaptation and resilience is an everyday reality for decision makers across the United States. Climate change is widely recognized as a critical – possibly existential – threat to humans, other species, and the natural systems on which all life depends. As climate impacts accelerate and population grows in vulnerable areas, disasters are more frequent and more devastating. Supercharged storms, catastrophic wildfires, and deadly heatwaves affect growing numbers of Americans – particularly those with low incomes who are least able to avoid or minimize the impact of severe events.
Communities across the country are experimenting with adaptation, defined as the management of and preparation for the impacts of global climate change and related extremes. They are aided by a growing knowledge base and suite of tools, and boosted by new actors including utility managers, private sector interests and philanthropy.
However, the field is largely crisis-driven and fails to adequately address the social equity aspects of adaptation choices, that should ensure all people benefit regardless of socio-economic status or race. It also lacks a shared vision, consistent funding and agreed upon best practices among other shortcomings, the report found.
“Our research revealed a growing core of professionals, committed municipal leaders, engaged community residents and others who are proactively identifying ways to make their cities and regions more resilient,” said author Susanne C. Moser. “But without much-accelerated efforts to expand and professionalize the adaptation field we fear communities, businesses and particularly the most vulnerable are at growing risk. To ensure their safety, well-being and prosperity, we must rapidly come together to slow the release of planet-warming greenhouse gases; invest in smarter, more resilient systems, infrastructure and planning practices; and do both while building social cohesion and equity.”
The report’s findings and recommendations were the basis of a next-steps conversation among several dozen climate-resilience experts and thought leaders at a January 22 workshop in Washington, D.C. At that meeting participants discussed ways to better disseminate promising resilience practices, embed climate resilience in planning and policymaking, and generate new financing mechanisms for the work.
The report recommends aggressive acceleration of adaptation planning, coordination across jurisdictions, and implementation among advocates, planners, and funders. Leaders must press the urgency of addressing climate change both through adaptation and mitigation – pushing the field to think bigger, bolder and deeper. At the same time, funding support must grow and policy incentives should be aligned to support the incorporation of resilience across different practices and sectors.
“This report highlights the urgency of building climate adaptation as a field of practice,” said Lois DeBacker, managing director of The Kresge Foundation’s Environment Program. “It is critical to expand the number of people who understand the imperative of acting quickly, which actions yield the best and most effective protections against climate change-fueled events, and how to approach climate resilience in ways that advance equity.”
The year 2017 will stay on the record as one of the most expensive years to date for climate and weather disaster events. The U.S. experienced 16 weather and climate disasters that caused over $1 billion in damages, tying the record year of 2011 for the most billion-dollar disasters. From summer through the fall, wildfires in various parts of California led to fatalities, destruction of entire communities, and damage costs of $18 billion, with economic consequences that will continue to impact the region. These events have highlighted that climate change has already begun to and will continue to impact local communities and businesses, and that local economies will benefit from more coordinated resilience planning.
Communities across the U.S. are taking steps to identify their climate change risks and enhance their resilience to changing climate conditions. Many local governments have assessed their vulnerabilities and are developing resilience plans with support from local stakeholders. However, a key set of stakeholders are often not at the table: businesses. Collaboration between local governments and the business community on climate change resilience remains limited. As local and regional climate change planning continues, it becomes increasingly important for local governments to engage with businesses, both large and small, on these issues.
The success of businesses and communities is intertwined
Many larger companies recognize the impacts of climate change on their operations, including risks to physical assets, disruptions to supply chains, and impacts on their workforce. In fact, some businesses, like Google, are examining how to develop company resilience strategies that address changing climate conditions. Businesses are also dependent on public infrastructure and local government services, and climate risks on these “outside the fence” components are much harder for businesses to evaluate. In fact, a number of companies have highlighted these uncertainties as a major barrier in addressing adaptation.
Local governments are dependent on the private sector in many ways. Businesses are essential to the economic health and growth of communities. Business interruptions can affect the quality of life for residents, disrupt the local economy, and reduce tax revenues. The costs of Hurricane Harvey are still being evaluated, but preliminary estimates suggest that lost economic output from this storm was in the range of $9 billion to $11 billion, including $540 million for goods-producing industries and $141 million for oil and gas industries. The October 2017 wildfires in California’s wine country are estimated to have caused economic losses between $6 and $8 billion dollars due to property damage and business interruptions alone, with $789 million in commercial property claims. These costs do not include the potential losses to the wine industry for many years to come.
Local governments have a strong interest in ensuring that businesses are resilient and remain operational as the climate continues to change. Companies will also benefit from engaging with the public sector on community resilience to enhance their business continuity plans and support their employees. In addition to better protecting their employees and operations, this type of collaboration will help businesses better understand community needs.
Businesses can assist local governments with expertise and solutions
Larger businesses often already understand local risks because of internal risk management processes. Risk management and emergency management plans, along with drills and training exercises with employees, help businesses prepare for extreme events. Local governments can coordinate with businesses on risk management, including participating in drills and trainings, to build and maintain community resilience.
Local governments can also use larger companies’ expertise and data on risk. Businesses may be monitoring information that could be relevant to local resilience planning. For example, utilities often track potential risks to their assets, such as those related to storms (e.g., wind, precipitation, flooding), wildfire, and temperature impacts on energy demand. This information can be helpful to local decision-makers in both emergency management and long-term resilience planning.
The private sector also offers opportunities in services and solutions. Businesses are often interested in developing and improving technologies, engineering approaches, technical assistance, and opportunities to connect with their communities. For example, Airbnb offered disaster relief to people impacted by the California wildfires, connecting displaced residents to available housing. The company also worked with the City of San Francisco’s Department of Emergency Management to share their lessons learned from Superstorm Sandy. Airbnb is also partnering with various local governments to help communities prepare for and recover from disasters. Local governments’ suggestions for climate change solutions and services can help businesses tailor their products to best serve the community.
In addition, financing for implementing community resilience can often be a challenge for local governments. The private sector can offer financing solutions to help fund climate change resilience. For example, Pacific Gas and Electric Company (PG&E) is investing $1 million over five years through their Better Together Resilient Communities grant program to support local climate resilience initiatives in California.
Local governments can share data and information with businesses
Some local governments have undertaken vulnerability assessments and climate change scenario planning for their regions. The data and results from these studies can be shared with businesses to help them understand what assumptions are being used by local governments, and whether their scenarios align, which will be increasingly important to ensure regional coordination as conditions change.
While larger companies may undertake scenario planning and vulnerability assessments, most small businesses do not. However, small businesses can also benefit from data and information sharing. Small companies do not often have the expertise or resources to adequately assess climate change risks and undertake resilience planning. Local governments can share information with small businesses to help them better understand their potential risks and prepare for extreme events. In California, Valley Vision has developed the Capital Region Business Resiliency Initiative to help engage the small business community in resilience planning. This effort helps small businesses engage with local stakeholders to understand potential risks and provides resources to help these businesses plan for disaster resilience.
Local governments can engage with businesses through existing networks or by creating new processes to assist with engagement
Local governments can engage with both small and large businesses through networks and organizations for the private sector, like local chambers of commerce, trade associations, and other business networking groups. For example, the City of Annapolis has engaged the Anne Arundel County Chamber of Commerce and the Downtown Annapolis Partnership in its Weather It Together initiative, which is focused on adapting the historic community to minimize the risks associated with flooding. Through this effort, local businesses are part of the planning process to help the community become more resilient. The City of Cambridge, Massachusetts has also engaged businesses in long-term planning efforts like the Cambridge Compact and the city’s Climate Change Preparedness & Resilience Plan. Establishing public-private partnerships focused on climate resilience will also help to facilitate conversations and collaboration between these two sectors.
Local governments may already engage with businesses individually, but it can be helpful to set up an ongoing process for involving the private sector in resilience planning. For example, business representatives can participate in local planning and advisory committees, contributing their perspectives and identifying any key issues for the business community. Effectively engaging the business community will often require targeted outreach and potentially different strategies, as businesses may not be aware of ongoing stakeholder processes or may not realize their relevance to company needs. Some communities have incorporated businesses into resilience planning through regional climate collaboratives. Several regional climate collaboratives in California focus on engaging different stakeholder groups, including businesses, to further climate change planning. For example, the Sierra Climate Adaptation and Mitigation Partnership was founded by the Sierra Business Council and has various business members, including ski resorts and forestry companies.
Effectively preparing for climate change’s impacts requires that cities coordinate with many different stakeholders. Businesses, public agencies, community groups, and citizens are all important to the discussion on community resilience, as they will all be impacted by climate change and have important ideas to contribute. Engaging the private sector is an important way for local governments to improve community resilience, and will benefit both the public and private sector through information sharing, aligning needs and goals, and developing multi-sector networks.
