5th Assessment Report
The Working Group III contribution to the IPCC’s Fifth Assessment Report (AR5) assesses literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change since 2007 when the Fourth Assessment Report (AR4) was released.
Special Report on Renewables
Special Report on Renewable Energy Sources and Climate Change Mitigation IPCC Working Group III; 2012
The IPCC Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) provides a comprehensive review concerning these sources and technologies, the relevant costs and benefits, and their potential role in a portfolio of mitigation options.
For the first time, an inclusive account of costs and greenhouse gas emissions across various technologies and scenarios confirms the key role of renewable sources, irrespective of any tangible climate change mitigation agreement.
Special Report on 1.5°C (SR15)
Limiting global warming to 1.5°C would require rapid, far-reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5°C compared to 2°C could go hand in hand with ensuring a more sustainable and equitable society, the Intergovernmental Panel on Climate Change (IPCC) said on Monday.
The Special Report on Global Warming of 1.5°C was approved by the IPCC on Saturday in Incheon, Republic of Korea. It will be a key scientific input into the Katowice Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change.

The U.N.’s climate report has something to piss everyone off, by Nathanael Johnson, in Grist, on 9 Oct 2018, [link]
... according to the blockbuster report out this week from the Intergovernmental Panel on Climate Change, it’s not enough to stick to your thing, or even to take up all of the causes environmentalists love. If we want to prevent the likely consequences of climate change — food shortages, forest fires, and mass extinctions — we’ll need to deploy the popular solutions as well as the some of the unpopular ones, the report concludes.
That means turning off coal plants and building lots of renewables, but also devoting more acres to growing biofuels. It means reducing consumption (fly less, drive less, and eat less meat) but also increasing our use of nuclear power.
