Thanks for the question. As saying goes, we are champions of our own destiny. So, in many respects, the answer to your first question is 'no'. They are not fait accompli - we have the ability to shape our own future. To avoid the climate stresses, first priority is decarbonisation of the global economy. This is happening, but the rate of change is slow. The basic equation is that a reduction in global emissions reduces the threat posed by climate change. So, that is key.
