Artificial algal blooms could remove atmospheric carbon — but can they be used responsibly?

TL;DR - Ocean iron fertilization could stimulate carbon-absorbing phytoplankton blooms, potentially removing atmospheric carbon. Its viability depends on whether broad ecological risks can be responsibly managed.

• Iron additions are intended to increase phytoplankton growth and carbon uptake.
• Ecological effects could spread far beyond the intervention site.
• The provided excerpt does not quantify carbon removal or specific ecosystem impacts.
• Responsible deployment requires assessing consequences across connected ocean systems.
