It's an interesting essay. It's not a science paper and was rightly rejected. In some ways it's just "McPherson Lite." This is his takeaway:
"Recent research suggests that human societies will experience disruptions to their basic functioning within less than ten years due to climate stress. Such disruptions include increased levels of malnutrition, starvation, disease, civil conflict and war – and will not avoid affluent nations."
He relies a fair amount on Wadhams to bolster his most dramatic claims about rapid climate unraveling, so there's that! The essay examines how we should approach our lives - and particularly how academics in climate and sustainability fields should approach theirs - IF we accept that near term collapse is unavoidable. He writes well and has some interesting things to say about that. But, I think it almost goes without saying that he has no more idea about whether or not the climate and civilization will unravel before 2030 than any reasonably well-read poster on this forum.
