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.
July 15, 2018 – 427 ANALYSIS: Record-setting rains in Japan led to floods and landslides that disrupted business operations of automobile manufacturers, electronic companies and others. Understanding the ownership and operations of facilities located in the damaged areas provides insight into what companies and industries may exhibit downturns in performance over the near term and be vulnerable to similar storms in the future.
Japan was the inundated by over 70 inches of rain in early July, an event that resulted in significant loss of life and business disruptions. The clouds have since receded, leaving economic damage with long-term implications yet to be understood. However, estimates expect industry losses to be in the billions USD. Destruction was centered in Okayama and Hiroshima, driven by flooding and landslides.
Typhoons Prapiroon and Maria contributed to this rainfall and climate scientists expect a warmer climate to increase the severity of these storms. Japan has fewer preparations in place for floods than it does for other extreme events, and understanding the various manifestations of risk caused by extreme rainfall is essential to mitigating damage in the future.
Much of Okayama sits immediately below mountains, which makes it particularly exposed to devastating landslides following significant rainfall events. Bursting pipes and power outages led over 250,000 homes in the Okayama and Hiroshima Prefectures to go without water for several days after the floods. Landslides destroyed homes and exacerbated infrastructure damage caused by flooding.
Many business operations were severely impacted by these events as well, and some facilities remain closed. Companies such as Panasonic experienced physical damage due to flooded facilities, and others were impacted by damaged infrastructure and communities, impacting their supply chains and workforce.
Okayama and Hiroshima are centers of economic activity for a number of key sectors in Japan, hosting production facilities for auto manufacturing, consumer electronics, retail trade and others. The figure below highlights the concentration of facilities of companies in the auto manufacturing industry by the sector of their operations. Companies that rely heavily on manufacturing operations are particularly vulnerable to flooding due in part to their utilization of expensive equipment that can easily incur water damage.
The heavy rainfalls showed no favorites in their disruption of manufacturing facilities across industries. For example, Mitsubishi and Mazda halted operations at some factories during the storms, due in part to supply chain disruptions. Many companies were also forced to pause operations because employees couldn’t get to work. While Mazda’s headquarters in Hiroshima Prefecture and a production facility in Yamaguchi Prefecture weren’t damaged themselves, they remained closed after the storms until employees could return to work safely. Likewise IHI Corp. closed its No. 2 Kure factory in Hiroshima because of water shortages and employees’ commute challenges.
The extent of long-term economic impacts that these companies will bear in the aftermath of last week’s storms is not yet known, but merits ongoing examination as the region recovers. Understanding the location of a corporation’s facilities and their exposure to extreme weather events is a key starting point for gauging exposure, and therefore can be instrumental in understanding company’s future performance.
Four Twenty Seven’s extensive facility level database can help investors proactively identify their portfolio companies’ exposures both to chronic climate effects and to individual extreme weather events such as the extreme rainfall that beset Okayama and Hiroshima. This deeper understanding can drive better risk-return tradeoffs, and importantly, shareholder engagement strategies that foster investments in resilience.
June 25, 2018 – 427 REPORT. Regulatory pressure and financial damage are necessitating an increase in physical climate risk disclosure in Australia. In exercising their own due diligence and assessing the exposure to physical climate risks in their portfolios, investors arm themselves with valuable information on corporate risk exposure which they can leverage to engage with companies around resilience. This report explores the connection between climate hazards and financial risks and shares examples of corporate adaptation and investor engagement to build resilience.
The global tide of interest in the Task Force on Climate-related Financial Disclosures (TCFD) has hit the shores of Australian financial markets, steered by regulators concerned about the systemic risk climate change poses to the economy. In 2017 Australian Prudential Regulation Authority’s Geoff Summerhayes was the first Australian regulator to formally endorse the TCFD. “Some climate risks are distinctly ‘financial’ in nature. Many of these risks are foreseeable, material and actionable now,” he said. This sentiment was echoed by John Price of the Australian Securities and Investments Commission in 2018 and reflects growing regulatory concern over climate risk disclosure internationally, as shown by Article 173 of France’s Law on Energy Transition and Green Growth and the 2018 European Commission Action Plan.
This Four Twenty Seven Report, Responding to Economic Climate Risk in Australia, explores the drivers of financial risk in Australia and discusses approaches to addressing this risk. The nation’s dominant industries are particularly threatened by the prevalent climate hazards. For investors, understanding a company’s risk to climate change is an essential first step to mitigating portfolio risk, but must be followed by corporate engagement to build resilience. Institutional investors are increasingly leveraging shareholder resolutions and direct engagement to prompt companies to disclose their climate risks and adapt.
This Four Twenty Seven webinar on emerging metrics and best practices for physical climate risks and opportunities disclosures covers recent developments in TCFD and Article 173 reporting, challenges to assessing climate risk exposure, strategies for investors to incorporate this information into decision-making and approaches to build corporate resilience.
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.
