What's the latest news on global efforts to address climate change?

The latest developments I can reliably verify are through COP29, held in Baku in November 2024. I can’t confirm decisions or progress after that date, so this isn’t a real-time update for 2026.

The headline outcome was a new COP29 climate finance target: developed countries are to take the lead in providing at least $300 billion a year for developing countries by 2035. The agreement also called for efforts to scale climate finance from all sources to $1.3 trillion annually by 2035. Many developing countries argued that the first figure falls short of what they need.

Negotiators also finalized rules for international carbon trading under Article 6 of the Paris Agreement. Supporters see the rules as a way to channel funding toward emissions cuts, while questions remain about how credits will be tracked and how to ensure they represent real reductions.

Countries were expected to submit stronger national climate plans in 2025, including targets for 2035. Those plans are a key test of whether governments’ emissions-cutting promises can keep pace with the Paris Agreement’s temperature goals.

One sobering backdrop: 2024 was the first calendar year with a global average temperature around or above 1.5°C over pre-industrial levels. A single year above that mark does not by itself mean the Paris long-term limit has been permanently exceeded, but it underscores how quickly climate risks are growing.

For a truly current picture, the outcomes of climate negotiations and new national plans since late 2024 would need to be checked against up-to-date reporting.

As of my last knowledge update in January 2022, global efforts to address climate change have seen increased momentum with nations making commitments to reduce emissions and transition to more sustainable practices. Some notable developments include:
COP26 Summit: The 26th UN Climate Change Conference of the Parties (COP26) took place in November 2021 in Glasgow, Scotland. 
Renewed Commitments: These pledges aim to align with the goals of the Paris Agreement.
Global Transition to Renewable Energy: Many countries accelerated their transition to renewable energy sources.
Methane Reduction Pledge: This commitment aims to address a potent greenhouse gas responsible for a significant portion of global warming.
Conservation and Reforestation Efforts: Efforts to protect and restore ecosystems gained attention. Reforestation projects and initiatives to conserve biodiversity were seen as crucial components of climate mitigation and adaptation.
Corporate and Financial Climate Commitments: Many businesses and financial institutions made commitments to align their operations with sustainability goals. The financial sector witnessed increased emphasis on incorporating climate-related risks into decision-making processes.

It's important to note that climate change efforts are ongoing, and developments may have occurred since my last update.
