So what? the people from the ipcc get their money streight from god himself or what?
People can claim "hey, some scientists might be getting paid to make claims that will make governments subsidize green technology, so their work is biased and not worthy of trust", but you can't say in the same breath "Hey this paper made by scientists who are
definitely getting paid by private companies that have a self-interest in the results is totally legit".
The IPCC is funded by the UN and bases its reports on the peer reviewed work. It does not pay scientists for contributing their work.
It is
extremely shady that:
They named their group NIPCC and published their work under that name (presumably to brand themselves to be as credible as the IPCC) without independent peer review.
They receive large amounts of funding from oil companies.
They claimed to have the endorsement of the CAS, but they do not.
