Geopolitical Risks of Climate Engineering: Marine Cloud Brightening Could Unexpectedly Weaken the El Niño Cycle

Research from the University of California, Santa Barbara indicates that climate intervention methods such as marine cloud brightening (MCB) could significantly weaken the El Niño–Southern Oscillation (ENSO), thereby creating cascading effects on global weather, agriculture, and ecosystems. This article examines this risk from a global development perspective, emphasizing the need for comprehensive assessments of regional impacts in climate governance, so as to avoid deepening development gaps through technological shortcuts.
