For the six states of the U.S. Southwest (Arizona, California, Colorado, Nevada, New Mexico, and Utah)i , January 2020 through August 2021 have been exceptional in the instrumental climate record since 1895, with the lowest total precipitation and the third-highest daily average temperatures recorded, which together imposed an unyielding, unprecedented, and costly drought. This exceptional drought punctuates a two-decade period of persistently warm and dry conditions throughout the region.
Safe and secure water supplies are a continuing fundamental pursuit for life in the West. This 2021 Report provides an assessment of climate change impacts to water uses in the West and adds a new set of West-wide information based in paleohydrology. This report describes our collaborative actions taken to increase the reliability of water and power deliveries since 2016, including: science and research, planning, infrastructure sustainability, efficient hydropower production, and on-the-ground actions to meet needs for irrigation, municipalities, power, Tribes, and the environment.
This report identifies eight distinct strategies cities are using to pay for large-scale climate resilience projects, mostly to address sea level rise and flooding. The analysis is based on a close look at how eight U.S. cities in seven states have been organizing the funding needed to implement their ambitious climate resilience plans. Each of these cities has had to find its own way to public and private financial resources, because there is no system in place for solving the problem of how to pay for climate resilience. Examining these cities’ pathways revealed common strategies that, while only reflecting the leading edge of urban climate resilience financing practices, quite likely foreshadow what other cities already or may do.
This user-friendly summary is based on the 2015 report “City of Long Beach Climate Resiliency Assessment Report" and “Appendices” prepared by the Aquarium of the Pacific at the request of Mayor Robert Garcia. The report includes clear infographics that describe current and projected conditions in the city. It also describe what the city is currently doing and what else the city and its residents can do.
In January 2015, Long Beach Mayor Robert Garcia asked the Aquarium of the Pacific to take a lead in assessing the primary threats that climate change poses to Long Beach, to identify the most vulnerable neighborhoods and segments of the population, and to identify and provide a preliminary assessment of options to reduce those vulnerabilities. Over the course of 2015, the Aquarium hosted and participated in meetings and workshops with academic and government scientists, business and government leaders, local stakeholders, and Long Beach residents to discuss key issues facing our community as the result of climate change. This report, completed in December 2015, represents the culmination of these efforts. The report offers detailed assessments of the five main threats of climate change to Long Beach: drought, extreme heat, sea level rise and coastal flooding, deteriorating air quality, and public health and social vulnerability. It also provides an overview of what is currently being done to mitigate and adapt to these threats, and other options to consider. Finally, this report presents a series of steps and actions that city leaders and community stakeholders can use as a template for making Long Beach a model of a climate resilient city.
The Sacramento-San Joaquin River Delta is the grand confluence of California’s waters, the place where the state’s largest rivers merge in a web of channels—and in a maze of controversy. In 2009, seeking an end to decades of conflict over water, the California Legislature established the Delta Stewardship Council with a mandate to resolve long-standing issues. The first step toward that resolution is the Delta Plan—a comprehensive management plan for California’s Sacramento-San Joaquin Delta, developed to guide state and local agencies to help achieve the co-equal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the delta's ecosystem.
This report presents the common trends in how 12 local governments across the country developed and implemented stormwater policies to support green infrastructure. The local policies examined include interagency cooperation, enforcement and management issues, and integration with state and federal regulations. While a strong motivation for these policies and programs is innovation in stormwater management, many communities are moving past the era of single objective spending and investing in runoff reduction and stormwater management strategies that have multiple benefits. Green infrastructure approaches have a range of benefits for the social, environmental, and economic conditions of a community. Not only do these case studies include success stories for building a comprehensive green infrastructure program, but they also provide insight into the barriers and failures these communities experienced while trying to create a stormwater management system that includes more green infrastructure approaches.
