- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.

- Nearly 100 Indigenous representatives agreed on a first-ever document to define what a just energy transition is from an Indigenous perspective, with eleven principles to make the transition fair and equitable.
- Another report highlights approaches for fair co-ownership models and negotiations between Indigenous communities and corporations in instances where communities agree to projects on their lands.
- To meet renewable energy goals, there will need to be an increase in mining for critical minerals that power renewable energy technologies, many of which are on Indigenous lands, say analysts.
- A researcher has proposed additional solutions to meet the growing demand while respecting the principles around a just energy transition, including a framework to track mineral needs and which mines truly serve climate purposes.

- A new scientific report lays bare the stark impacts of land-system change and land degradation on planetary health, while also offering solutions to these problems. The report was published on the eve of the 16th session of the UN Convention to Combat Desertification, running Dec. 2-13 in Riyadh, Saudi Arabia.
- Seven of nine planetary boundaries are now adversely impacted by unsustainable land use and other land practices, the report finds. Six of those boundaries are already transgressed, having moved beyond their safe operating space for humanity and into the high-risk zone.
- Scientists warn that the seriously degraded land use boundary, interacting with the other transgressed planetary boundaries, could result in a domino-effect that may rapidly push Earth systems past dangerous and irreversible tipping points, threatening life as we know it.
- Unsustainable agricultural practices are a leading driver of land use degradation globally, responsible for vast amounts of greenhouse gas emissions, the majority of deforestation and freshwater use. Urgent measures are needed to restore ecosystems, shift to sustainable agriculture, and prevent further degradation.
