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.
