In short, it implies that #LightPollution is decreasing the efficiency with which #plants remove carbon from the atmosphere. It concludes that artificial light at night increases “ #ecosystem respiration” (plants, microbes, and animals releasing carbon dioxide through their activity and growth), but there is no corresponding increase in #photosynthesis.

The result is that plants exposed to ALAN emit more #carbon than they absorb from the #atmosphere. The authors write: “Our findings show that ALAN disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments.”

Marine experts at the Indonesian Seagrass Symposium in Bali warned that seagrass ecosystems — vital for carbon storage, biodiversity and coastal protection — remain largely overlooked in national policy and conservation efforts.

Scientists and conservation leaders urged stronger data collection, funding and institutional capacity to support restoration, monitoring and community participation.
