(...) provides regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation.
, and is not a political thinktank (even though climate risk deniers and minizers might like to claim it is), is funded at least by 65% by nation states and the UN (44% USA in 2018, 25% by the next inheriting their democratic legitimacy w.r.t to funding any money) and fundamentally deals with something much more narrowly defined, empirically verifiable and graspable than the TUA main causes.
