Selected through an international call for science communicators, I’m working alongside an international team of scientists from #geology and #microbiology. Operated by JAMSTEC/MARE3, the Chikyu is coring sediment from more than 7,600 m water depth in the hadal zone. These cores help uncover megathrust earthquake and tsunami histories, and offer new insights into deep-sea trenches, the #carbon cycle, and #climate.

Liberia's "carbon credit" deal with a little-known Dubai company has stalled after over two years, with other accords with the company across Africa and elsewhere having also gone nowhere. https://www.japantimes.co.jp/environment/2025/11/26/climate-change/africa-carbon-deals/?utm_medium=Social&utm_source=mastodon #environment #climatechange #africa #carbon #climatechange #environment #liberia #unitedarabemirates

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 scientists and Chumash tribal leaders are successfully restoring #California's #kelp #forests through collaborative efforts that combine traditional knowledge with modern techniques.

Researchers have achieved significant successes including an 80-acre restoration near #LosAngeles while developing kelp #farming for #carbon capture and agricultural biofertilizers that could help California reach #netzero #emissions.

Companies and groups backing carbon-capture technology, which critics slam as an excuse to keep burning fossil fuels, have deployed more than 500 participants to the COP30 climate talks, an NGO list has shown. https://www.japantimes.co.jp/environment/2025/11/17/climate-change/carbon-capture-cop30-ngo/?utm_medium=Social&utm_source=mastodon #environment #climatechange #carbon #cop30 #emissions #climatechange #environment #brazil

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.
