IPCC Sixth Assessment Report (AR6)

By Intergovernmental Panel on Climate Change (IPCC).
The Summary for Policy Makers (draft) [https://report.ipcc.ch/ar6syr/pdf/IPCC_AR6_SYR_SPM.pdf] is marked as "Approved" but "Do Not Cite, Quote or Distribute". That said, there are many many aspects of interest. E.g.:
"A.4.2 Several mitigation options, notably solar energy, wind energy, electrification of urban systems, urban green infrastructure, energy efficiency, demand-side management, improved forest- and crop/grassland management, and reduced food waste and loss, are technically viable, are becoming increasingly cost effective and are generally supported by the public. From 2010– 2019 there have been sustained decreases in the unit costs of solar energy (85%), wind energy (55%), and lithium ion batteries (85%), and large increases in their deployment, e.g., >10x for solar and >100x for electric vehicles (EVs), varying widely across regions. The mix of policy instruments that reduced costs and stimulated adoption includes public R&D, funding for demonstration and pilot projects, and demand pull instruments such as deployment subsidies to attain scale. Maintaining emission-intensive systems may, in some regions and sectors, be more expensive than transitioning to low emission systems. (high confidence)...."

There are interesting variations of how this report is portrayed in news media. For example, compare the headlines in The New York Times, "Climate Change Is Speeding Toward Catastrophe. The Next Decade Is Crucial, U.N. Panel Says", with The Guardian, "World can still avoid worst of climate collapse with genuine change, IPCC says."
