I am convinced the ruling class has been pushing this idea MAINLY to transition their control of the world's electricity supply from petroleum and coal to Uranium-based nuclear power, something they can control because of it's connection to nuclear weapons. A very informative video of Allan Savory giving a talk on TedTalks ( https://www.youtube.com/watch?v=vpTHi7O66pI ) has recently come to my attention and now I am convinced, since his thesis of the true cause of climate change being desertification has been proven and known for decades now, that the reason the ruling class ignores his prescription for a solution that would not only solve the climate change problem, but would also solve many other problems such as feeding a growing population with what many people like the most, meat, that they don't want his solution now because a changing climate can help them rehabilitate the public image of nuclear power. The silence from the media and their lords of capitalism on desertification is deafening given the supposed crisis they cry like banshees over. I am convinced this means their agenda MUST be not about money per se, but about power: the real means of controlling society, to paraphrase Frank Herbert's Baron Harkonnen, "Who controls the electricity, controls the world." Thank you
Whether or not private capitalists "caused" the environmental problems confronting us all - alone or together with other social forces - the issue you raised stands: those corporations cannot and do not address the problem as something urgent to be solved. Instead, for them the priority problem is howe to avoid financial losses and/or obtain profits from such problems whether or not they are "solved." That is how capitalism stands exposed as an inadequate economic system.
