You are quite right is asking, what will it take? Given the severity of our current predicament, I find it astonishing that there isn't a more global concerted effort. Looking at the covid 19, scientists were able to unite together and find several vaccines so we certainly have the ability. Perhaps this will only take place when the climate crisis reaches a catastrophic breaking point. But, of course by then, it may be too late. It would be great if scientists could discover a bateria that eats carbon dioxide. As ever, we shall have to wait and see. Thank you kindly for your comment and hope that you are well!
