RegionsAdapt Brief Report 2019

By joining the RegionsAdapt initiative, regional governments commit to annually disclose their data on climate risks and adaptation through CDP’s States and Regions questionnaire. Each year, Regions4 publishes a summary of the data to inform about regional governments’ ambitious actions to adapt to climate change. The annual disclosure process helps RegionsAdapt members to better understand the risks they face from climate change, measure their progress and learn from each other’s adaptation actions.

2020 Water Resilience Portfolio

Water is central to nearly everything we value in California. Healthy communities, economies, farms, ecosystems and cultural traditions depend on steady supplies of safe and affordable water.

Those values are increasingly at risk as California confronts more extreme droughts and floods, rising temperatures, depleted groundwater basins, aging infrastructure and other challenges magnified byclimate change. For some of California’s most vulnerable populations, the risks are particularly acute.

Conserving California’s Coastal Habitats: A Legacy and a Future with Sea Level Rise

To inform current and future adaptation decisions and conservation actions we conducted the first statewide, comprehensive assessment of the vulnerability of California’s coastal habitats, imperiled species, and conservation lands to sea level rise. Coastal habitats exist in narrow bands at the land-sea interface and are therefore extremely susceptible to inundation by sea level rise. However, some habitats may be able to adapt vertically and possibly move inland, assuming local topography and the built environment do not constrain this movement.

Texas Fish and Game in a Changing Climate

Texas sportsmen and women know that the species they prize are highly attuned to climate. Climate change is already resulting in many changes that are being observed across land and water habitats, including changes in the types of fish, wildlife and plants, their population size, and shifts in where and when species are found. This publication describes some of the effects that have already been seen in Texas and what may be in store for the state's fish and game in the future.

Florida Climate Adaptation Explorer

Tool Overview

The Climate Adaptation Explorer (CAE) provides a starting point from which to address the predicted impacts of climate change on Florida's fish, wildlife, and ecosystems. The CAE provides an easy to navigate format for users to access a broad array of climate change information. Content includes an overview of climate change, impacts of climate change in Florida, impacts on Florida's species, impacts on Florida's ecosystems and habitats, interactions with existing stressors, and vulnerability to climate change.

The California Heat Assessment Tool

Tool Overview

California’s climate is warming and 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.

Adapting to the Changing Climate: An Assessment of Local Health Department Preparations for Climate Change-Related Health Threats, 2008-2012


Climate change poses a major public health threat. A survey of U.S. local health department directors in 2008 found widespread recognition of the threat, but limited adaptive capacity, due to perceived lack of expertise and other resources.


The State of Climate Adaptation in Public Health: An Assessment of 16 U.S. States

Climate change poses significant threats to the health of individuals and communities, as well as the delivery of healthcare services. Human morbidity and mortality rates are rising due to extreme heat events and changing patterns of water-borne and vector-borne diseases, and healthcare infrastructure is at risk from extreme events. Climate adaptation actions are taken to either avoid or take advantage of climate change impacts either by decreasing vulnerability or increasing resilience.

Preparing for the public health impacts of climate change through the Michigan Climate and Health Adaptation Program

Projected climate impacts for Michigan, including extreme heat events, extreme precipitation events leading to flooding, and extreme weather events (e.g., freezing rain, heavy snow), pose a significant threat to public health. In particular, five priority climate-related health outcomes have been identified: heat-related illnesses, air quality and respiratory diseases, vector-borne diseases, water-borne diseases, and injuries related to extreme weather events (e.g., carbon monoxide poisoning, injury).
