491: 1786:, argued in 2007 that the IPCC's tendency to make conservative risk assessments had benefits. Rahmstorf argued that "In a way, it is one of the strengths of the IPCC to be very conservative and cautious and not overstate any climate change risk". IPCC reports aim to inform policymakers about the state of knowledge on climate change. They do this by assessing the findings of the thousands of scientific papers available on the subject at a given time. Individual publications may have different conclusions to IPCC reports. This includes those appearing just after the release of an IPCC report. This can lead to criticism that the IPCC is either alarmist or conservative. New findings must wait for the next assessment for consideration. 175: 47: 1628:(SRCCL) examined how the way we use land affects the climate. It looked at emissions from activities such as farming and forestry rather than from energy and transport. It also looked at how climate change is affecting land. All three IPCC working groups and its Task Force on National Greenhouse Gas Inventories collaborated on the report. The report found that climate change is adding to the pressures we are putting on our land we use to live on and grow our food. It will only be possible to keep warming well below 2 °C if we reduce emissions from all sectors including land and food, it said. 1588:
fossil fuels. The report noted that the cost of most renewables technologies had fallen. It was likely to fall even more with further advances in technology. It said renewables could increase access to energy. The report reviewed 164 scenarios that examine how renewables could help stop climate change. In more than half of these scenarios, renewables would contribute more than 27% of primary energy supply in mid-century. This would be more than double the 13% share in 2008. In the scenarios with the highest shares for renewable energy, it contributes 77% by 2050.

It would also mean rapid, far-reaching changes in all aspects of society. The report showed warming of 2 °C would have much more severe impacts than 1.5 °C. In other words: every bit of warming matters. SR15 had an unprecedented impact for an IPCC report in the media and with the public. It put the 1.5 °C target at the centre of 1908:, explained in 2007 the difficulties of establishing scientific consensus on the precise extent of human action on climate change. "Contributing authors essentially are asked to contribute a little text at the beginning and to review the first two drafts. We have no control over editing decisions. Even less influence is granted the 2,000 or so reviewers. Thus, to say that 800 contributing authors or 2,000 reviewers reached consensus on anything describes a situation that is not reality", he wrote. 2030: 1226:
Meeting on Communication in February 2016, at the start of the Sixth Assessment Report cycle. Members of the old and new Bureaus worked with communications experts and practitioners at this meeting. This meeting produced a series of recommendations. The IPCC adopted many of them. One was to bring people with communications expertise into the Working Group Technical Support Units. Another was to consider communications questions early on in the preparation of reports.
1297: 2044: 1877:, released its report on 1 September 2010. The IAC panel made seven formal recommendations for improving the IPCC's assessment process. The IPCC implemented most of the review's recommendations by 2012. One of these was the introduction of a protocol to handle errors in reports. Other recommendations included strengthening the science-review process and improving communications. But the IPCC did not adopt the proposal to appoint a full-time executive secretary. 1379:

Finally government representatives together with the authors review the Summary for Policymakers.

This final review of the Summary of Policymakers takes place at sessions of the responsible working group or of the Panel.
