With more and more people affected directly or indirectly by (flash) floods, forest fires and irregular droughts, no amount of “advertising” and “public relation” will assuage mobs of angry/desperate/displaced individuals from seeking irrational forms of justice that could never reasonably make their life whole again for all that was lost.
Moreover, we will enter (have already) a period whereas politicians will find it more and more acceptable to misdirect our woes/anger toward, at first, individuals/groups/corporations/countries unrelated to the causes of climate change as convenient scapegoat. Eventually as things progress (as in decline/worsen/degenerate), they will ultimately find themselves only viably electable by repudiating anyone/anything directly or even barely related to the fossil fuel industry.
Advertising / lobbying is one of their last attempt to avoid accountability.
Nevertheless, advertising and lobbying will never decrease the many real/visible/lived/experienced consequences of climate change.
