Future HAB science: Directions and challenges in a changing climate

Area of Science:

• Marine Biology
• Environmental Science
• Oceanography

Background:

• Human-induced global warming is altering environmental conditions.
• These changes influence phytoplankton, potentially intensifying harmful algal blooms (HABs).
• Significant uncertainty exists regarding the integrated effects of climate drivers on future HABs.

Purpose of the Study:

• To address research challenges in understanding HABs and climate change linkages.
• To identify new research directions for better defining these connections.
• To explore various aspects of HABs, including cyanobacterial and benthic forms, and their impacts.

Main Methods:

• Collective deliberations from a symposium on HABs and climate change.
• Consideration of physical, chemical, and biological drivers.
• Exploration of modeling challenges and molecular approaches.

Main Results:

• Consensus on the need for new research courses and practices to forecast HAB trends.
• Integration of laboratory and field studies, observational programs, and socioeconomic analyses.
• Identification of mitigation strategies as a research priority.

Conclusions:

• Accelerated, interdisciplinary efforts are needed to understand and predict future HAB trends.
• Focused research on a subset of HAB species and questions can fast-track advances.
• Urgent action is required due to substantial climate-driven changes in coastal systems.
