The author talks about cancer diagnoses. This is an apt analogy, and there is a huge body of science for helping individuals cope with personal tragedy. Global warming is a global and personal tragedy. People will have their livelihoods ruined, and people will die. People already have, but (since this is a anglophile community) this forum is mostly insulated from developments in North Africa, the Middle East, Central America... how it impacts us is in the nationalistic/xenophobic movements around the resulting human migrations. Acknowledging this will prevent conflict and harm those that cynically try to take advantage of groups of people in vulnerable states through demagoguing.
The science should be cold an unemotional. The policy dictated by the science should be sensitive to the mental health of everyone as they absorb the magnitude of this disaster.
