As Rising Seas Disrupt Toxic Sites, Communities of Color Are at Most Risk
As rising seas threaten to flood hundreds of toxic sites along the California coast, the risk of flood-related contamination will fall disproportionately on the state’s most marginalized communities, finds a new study published Tuesday by researchers at UC Berkeley, UCLA and Climate Central. San Mateo and Alameda counties are projected to host the most at-risk hazardous sites by 2050, but by 2100, Orange County is projected to surpass both as oil and gas wells there and in Los Angeles County face rising coastal flood risks.

As rising seas threaten to flood hundreds of toxic sites along the California coast, the risk of flood-related contamination will fall disproportionately on the state’s most marginalized communities, finds a new study published Tuesday by researchers at UC Berkeley, UCLA and Climate Central.
San Mateo and Alameda counties are projected to host the most at-risk hazardous sites by 2050, but by 2100, Orange County is projected to surpass both as oil and gas wells there and in Los Angeles County face rising coastal flood risks.
Under California’s high-risk aversion scenario, which projects that sea levels could rise by more than 6 feet by the end of the century, the study identified 736 facilities at risk of coastal flooding and an additional 173 with projected groundwater encroachment.
Residents living within 1 kilometer of at-risk sites were more likely than others to be people of color, to be living below the poverty line, to be unemployed or to experience another form of social disadvantage such as linguistic isolation.
As part of the study, the researchers also released a new interactive online tool in English and Spanish that allows users to map toxic sites that are at risk of coastal flooding, either by county or by individual facility.

Users can also overlay indicators of nearby residents’ social vulnerability, including the percentage of people who are living below the poverty line, who are experiencing unemployment, or who don’t have a high school degree.
“Sea level rise is like a slow-moving storm that we can anticipate and prepare for,” said Rachel Morello-Frosch, a professor of public health and of environmental science, policy and management at UC Berkeley and senior author of the paper. “As California invests in community resilience to climate change, it is essential that considerations of environmental justice are at the fore.”
Low-income communities and communities of color already face disproportionate exposure to myriad environmental pollutants, and the threat of additional exposures from sea-level rise will only exacerbate these inequities.
Compared to their neighbors, socially vulnerable residents can also face more challenges to evacuate during a flood and often experience social stressors that can make them more susceptible to the health impacts of pollutant exposures.
“Again, climate change amplifies inequality,” said lead author Lara Cushing, an assistant professor of environmental health sciences at the UCLA Fielding School of Public Health. “Sea level rise will present additional risks of contaminant releases to communities already living with pollution sources in their backyards.”
The study was conducted as part of the Toxic Tides project, which brought together a multidisciplinary research team with community advocacy organizations to understand how rising seas would impact hazardous sites, including refineries, industrial facilities, sewage treatment plants and cleanup sites.
The team released a preliminary set of data and an earlier version of the online mapping tool in November 2021; the new, peer-reviewed study, which appears in the journal Environmental Science and Technology, includes additional analysis about the environmental justice implications of the findings.

OP-ED: Oregon Bill Threatens the Future of Black Owned Newspapers and Community Journalism
BLACKPRESSUSA NEWSWIRE — Nearly half of Oregon’s media outlets are now owned by national conglomerates with no lasting investment in local communities. According to an OPB analysis, Oregon has lost more than 90 news jobs (and counting) in the past five years. These were reporters, editors and photographers covering school boards, investigating corruption and telling community stories, until their jobs were cut by out-of-state corporations.

For decades, The Skanner newspaper in Portland, the Portland Observer, and the Portland Medium have served Portland, Oregon’s Black community and others with a vital purpose: to inform, uplift and empower. But legislation now moving through the Oregon Legislature threatens these community news institutions—and others like them.
As President and CEO of the National Newspaper Publishers Association (NNPA), which represents more than 255 Black-owned media outlets across the United States—including historic publications like The Skanner, Portland Observer, and the Portland Medium—l believe that some Oregon lawmakers would do more harm than good for local journalism and community-owned publications they are hoping to protect.
Oregon Senate Bill 686 would require large digital platforms such as Google and Meta to pay for linking to news content. The goal is to bring desperately needed support to local newsrooms. However, the approach, while well-intentioned, puts smaller, community-based publications at a future severe financial risk.
We need to ask – will these payments paid by tech companies benefit the journalists and outlets that need them most? Nearly half of Oregon’s media outlets are now owned by national conglomerates with no lasting investment in local communities. According to an OPB analysis, Oregon has lost more than 90 news jobs (and counting) in the past five years. These were reporters, editors, and photographers covering school boards, investigating corruption, and telling community stories, until their jobs were cut by out-of-state corporations.
Legislation that sends money to these national conglomerate owners—without the right safeguards to protect independent and community-based outlets—rewards the forces that caused this inequitable crisis in the first place. A just and inclusive policy must guarantee that support flows to the front lines of local journalism and not to the boardrooms of large national media corporations.
The Black Press exists to fill in the gaps left by larger newsrooms. Our reporters are trusted messengers. Our outlets serve as forums for civic engagement, accountability and cultural pride. We also increasingly rely on our digital platforms to reach our audiences, especially younger generations—where they are.
We are fervently asking Oregon lawmakers to take a step back and engage in meaningful dialogue with those most affected: community publishers, small and independent outlets and the readers we serve. The Skanner, The Portland Observer, and The Portland Medium do not have national corporate parents or large investors. And they, like many smaller, community-trusted outlets, rely on traffic from search engines and social media to boost advertising revenue, drive subscriptions, and raise awareness.
Let’s work together to build a better future for Black-owned newspapers and community journalism that is fair, local,l and representative of all Oregonians.
