WMO report says Southwest Pacific's last tropical glacier may disappear within months

The World Meteorological Organization (WMO) released a report on Tuesday warning that the Southwest Pacific is confronting escalating climate risks as its extensive ocean waters become increasingly hot, acidic and hazardous for coastal populations. The assessment highlights a measurable rise in sea surface temperatures across the region, with average increases of 0.4 °C to 0.6 °C over the past three decades, alongside a steady drop in pH levels that signals heightened ocean acidification. These changes are linked to more frequent and intense tropical cyclones, accelerated coral bleaching, and disruptions to marine ecosystems that support fisheries and tourism.

The WMO report underscores that the combined effects of warming, acidification and sea‑level rise threaten the livelihoods and safety of millions living in low‑lying islands and coastal communities. It calls for immediate implementation of mitigation strategies to curb greenhouse‑gas emissions and for strengthened adaptation measures, including coastal defenses, resilient infrastructure and ecosystem‑based management. Regional governments and international partners are urged to coordinate efforts to reduce vulnerability and safeguard the socioeconomic stability of the Southwest Pacific.
