Sorry but I've lived too long to believe everything every so- called expert claims who think they have a handle on the "truth"..
"So-called"? Have you checked their credentials, and the process to produce such a report
About the IPCC special report, that I linked to:
"107 experts from 52 countries were selected as Coordinating Lead Authors and Lead Authors – who are working on each individual chapter – and Review Editors, who ensured that comments by experts and governments were given appropriate consideration as the report developed."
and
"A call for nomination of authors was sent to governments, observer organizations and IPCC Bureau Members on 5 April 2017. Graphics that provide background information about the nominees are available here"
Cheers,
