A Gray Tsunami

This month, I found myself on a stakeholder panel for a series of three workshops on the Climate Resiliency Sub Element of the Comprehensive Plan, required by the State Department of Commerce as part of the county’s comprehensive plan update. The first workshop was on sea level rise. For a primer on the sea level rise issues our island is facing, you can read An Imperfect Storm. Continue reading A Gray Tsunami

Sea water intrusion – it ain’t just salt

‘These levels are crazy’: Louisiana tap water sees huge spike in toxic chemicals | Louisiana | The Guardian Sea water is naturally high in bromide and contains bacteria that require disinfection. The chlorine reacts with bromine for form bromine, which contributes along with the chlorine to disinfection byproducts such as trihalomethanes (THMs) and haloacetic acids (HAAs). This is what’s happening right now is Louisiana as the combination of drought and rising sea levels has pushed salt water into the Mississippi River. ‘Everything out the faucet is salt’: Louisianans struggle as drinking water crisis persists | Louisiana | The Guardian This … Continue reading Sea water intrusion – it ain’t just salt

A Data-Driven Approach for Assessing Sea Level Rise Vulnerability Applied to Puget Sound, Washington State, USA

Abstract Sea level rise (SLR) will exert pressures on assets with social value, including things such as infrastructure and habitats, in the coastal zone. Assessing and ranking the vulnerability of those assets can provide insights that support planning and projects … Continue reading A Data-Driven Approach for Assessing Sea Level Rise Vulnerability Applied to Puget Sound, Washington State, USA

New Bay Area maps show hidden flood risk from sea level rise and groundwater

Amid dramatic ocean swells and drenching atmospheric rivers, a new report lays bare a hidden aspect of sea level rise that has been exacerbating flooding in the Bay Area.

The report, which was released Tuesday, maps areas that could flood from groundwater hovering just a few feet, or even inches below ground. This layer of water gets pushed upward as denser water from the ocean moves inland from rising tides. On its way up, even before the water breaks the surface, it can seep into the cracks of basements, infiltrate plumbing, or, even more insidiously, re-mobilize toxic chemicals buried underground.
