Uncharted Waters: Examining the Risks of Marine Geoengineering at Climate Week NYC

See the page at Climate Week 's website. More on Susanna Lidström's work here .

"As the climate crisis intensifies, marine geoengineering (MGE) has emerged as a controversial set of proposed interventions aimed at altering ocean chemistry or ecosystems to remove carbon dioxide from the atmosphere. Proponents argue that these techniques - such as ocean alkalinity enhancement, ocean fertilization, and biomass sinking - may be necessary tools to meet climate targets, and startups have already begun selling carbon credits and deploying these approaches. Yet mounting concerns have been raised about the ecological, ethical, and geopolitical risks of intervening in marine systems at scale.

This panel convenes experts in oceanography, marine ecology, and environmental social science to examine the scientific and societal implications of MGE. The panel will not only spotlight emerging scientific evidence but also raise critical questions: Who gets to decide what constitutes an “acceptable” risk to ocean systems? Can environmental harms be meaningfully monitored and contained? Are any MGE techniques appropriate for commercialization and sale on carbon markets? And what are the consequences of investing public and political attention in technologies that may never prove viable at scale? In a time of climate urgency, this panel asks whether marine geoengineering represents innovation - or a dangerous distraction."
