Sorry to say but this is a story which does not standup scientific scrutinity! Climate is changing, true, humans do play a role but far smaller than predicted by models which so far are almost speculative. Observations are therefore mandatory and only paleoclimatological results are spanning long enough periods to have a meaningful story to tell. Recent results from the last few years ever more clearly show that the sun is by far(!) the biggest and totally neglected factor. Therefore it seems very likely there will be famines caused by excessive cooling within the next few decades. There are multiple published peer reviewed results suggesting this even from Sept. 2019. Therefore follow the rule to look twice at the opposite views before you solidify your own position and always be prepared to change your own position. The crowd is far too easy to be led astray.
