In reply to ablackett:
Sustainability, clean air and low impact industrial activity have been on the scientific and engineering agenda for a very very long time. I was going to lectures about all that stuff 40 years ago. Only more recently have we had to listen to the whole carbon and global warming veneer that prevents most of the population understanding that we haven't a clue how all this really works.
People have been telling us it's all about the sun for quite some time. Only recently has it become mainstream.
Chaotic complexity makes the subject difficult to analyse. Some research points toward there being limited numbers of individuals who can understand particular chaotic systems. We may have to wait for sufficient numbers of such individuals to be born and rise to appropriate positions of influence before we get a definitive answer to problems of climate change. Supercomputers can't do it on their own: somebody has to programme them!
