The International Union for Conservation of Nature says it advanced its nature, ocean and climate agenda during the UN General Assembly and New York Climate Week. The organisation used the gatherings of world leaders, businesses and campaigners to press for stronger action on protecting ecosystems and oceans alongside emissions cuts. Details of specific commitments or outcomes were not given in the announcement.

A new examination challenges the frequent corporate argument that individual companies' fossil fuel emissions are insignificant compared to global totals. The piece asks what the true cost of those emissions would be if they were fully counted, pushing back on a common justification used by major polluters to downplay their share of responsibility for climate change.

UNESCO has unveiled its ONE OCEAN installation in New York during the UN General Assembly. The artwork puts the state of the world's oceans in front of world leaders gathering for high-level diplomacy, adding ocean protection to the agenda at a moment when climate and marine conservation remain contested topics globally.

UN News reports that the recent global energy crisis has accelerated the shift toward renewable energy, changing how countries think about energy security. The piece argues that renewables reduce dependence on volatile fossil fuel markets and imported supplies, turning the transition into a security strategy rather than only a climate goal. It highlights how governments are rethinking infrastructure and supply chains to build more resilient, domestically sourced energy systems.

Global leaders are gathering on the sidelines of the UN General Assembly to discuss the future of development finance, with a focus on how multilateral lenders can fund sustainable growth. CAF, the Development Bank of Latin America, is highlighting its role in shaping financing models for emerging economies. Discussions centre on reforming global financial systems so developing countries can access affordable capital for infrastructure and climate priorities.

Yale School of the Environment experts shared five main takeaways from Climate Week NYC, summarising key discussions on climate action held alongside the UN General Assembly. The school's roundup highlights what environmental scholars view as the most significant developments and priorities emerging from the annual New York gathering of policymakers, businesses and climate advocates.

Palau's President is drawing attention for his country's efforts to combat climate change, outlining his mission to protect the small Pacific island nation from rising seas and other climate threats. The story highlights Palau's advocacy on the world stage, where its leader argues that low-lying island states are on the front line of a crisis they did little to cause.

A new colloquium published in the American Physical Society's journals examines the scientific legacy of Syukuro Manabe, whose pioneering computer models laid the foundation for simulating and understanding global warming. Manabe's work, recognized with the 2021 Nobel Prize in Physics, remains central to modern climate science, and the review traces how his early simulations shaped today's understanding of rising temperatures.

A UK climate minister has warned that the global food system is vulnerable to El Niño, the periodic warming of Pacific Ocean waters that disrupts weather patterns and can hit crop harvests. The warning highlights concerns that extreme weather linked to El Niño could drive up food prices and threaten supply security at a time of already strained agricultural conditions.
