Marine heatwaves (MHWs) are increasingly affecting tropical seas, causing mass coral bleaching and mortality in the wider Caribbean (WC) eastern Pacific (ETP). This leads to significant loss, reduced biodiversity, impaired ecological functions. Climate models forecast a troubling future for Latin American reefs, but downscaled projections WC ETP remain limited. Understanding regional temperature thresholds that threaten reef futures restoration efforts is critical. Our goals included analyzing historical trends July–August–September–October (JASO) anomalies exploring at subregional country levels. From 1940 2023, JASO air ocean showed increases. Projections indicate even under optimistic scenario 4.5, temperatures may exceed +1.5 °C threshold beyond pre-industrial levels by 2040s +1.0 annual maximums 2030s, resulting severe mortality. Business-as-usual 8.5 suggests conditions will become intolerable conservation with decadal warming largely surpassing rates, unbearable corals. The immediate development of local adaptive plans, along climate change adaptation mitigation strategies, essential provide time scenarios materialize.

Reef-building corals are integral ecosystem engineers of tropical reefs but face threats from climate change. Investigating genetic, epigenetic, and environmental factors influencing their adaptation is critical. Genomic resources essential for understanding coral biology guiding conservation efforts. However, genomes the genus Acropora limited to highly-studied species. Here, we present assembly annotation genome DNA methylome pulchra Mo’orea, French Polynesia. Using long-read PacBio HiFi Illumina RNASeq, generated most complete date (BUSCO completeness 96.7% metazoan genes). The size 518 Mbp, with 174 scaffolds, a scaffold N50 17 Mbp. We predicted 40,518 protein-coding genes 16.74% in repeats. methylation CpG context 14.6%. This A. will support studies coastal Polynesia, aiding comparative cnidarians.
