Implication

Review reveals rising marine disease epidemics across ocean taxa, indicating that climate-induced thermal stress and human-assisted transport accelerate novel pathogen emergence.

Key Points

To review the interactions between climatic anomalies, human activity, and the emergence of marine epidemics across major ocean taxa.
Synthesis of monitoring records regarding disease frequencies and mass mortality events in marine taxa, focusing on corals and marine mammals.
Analysis of historical climate events, particularly 1997–98 El Niño thermal stress, alongside pathogen range extensions and host shifts.
Monitored marine taxa exhibit increasing epidemic frequencies and novel disease emergence coincident with severe temperature-driven coral bleaching events during 1997–98 El Niño.
Climate-mediated physiological stress diminishes host immune resistance, markedly elevating vulnerability to opportunistic pathogens.
Novel marine outbreaks are largely driven by pathogen host or range shifts facilitated by climate changes and human-mediated global species movement.
