While I sympathize with your sentiment a more accurate and less provocative way of saying almost the same thing would be to say that the biggest barriers to dealing with climate change are social and political, and so changing social norms (so corporate behavior as evidenced by Murdoch) becomes unacceptable, and electing politicians who will pass meaningful climate-change laws, is really important.
One is the ordinary corporate manager which is not especially ideological. This person might be part of the problem because CO2 emissions help the firm make money, but they'd have no deep problem with making money without CO2 emissions.
Another is Rupert Murdoch, the Koch Brothers, and other funders of the "new right" who actively campaign to make governments less responsive to issues such as climate change -- predominantly by spamming the agenda so that politicians never get far past "lowering taxes for the rich".
A third is the ordinary people, which makes the problem particularly difficult. In most countries the #1 way to have a riot is to raise the price of fuel. For instance, after Macron destroyed his credibility by cutting the wealth tax, he was unable to ask the "yellowjackets" to make any sacrifices. Now he can't manage pension "reform" for the same reason.
