I have no idea if they have their own agenda, but their ends (such as supporting private transportation and meat consumption) I support. Even if I didn’t trust them, and I don’t trust them either, the ends justify the means.
Please avoid snarky tropes like this on HN.
I think climate research is orthogonal to any political agenda, i.e. opposing private transportation and meat consumption doesn't follow from accepting that the climate is getting warmer and the validity of political agendas has no effect on the authenticity of climate research data.
