Interesting article. I googled “Rummel” and “democide,” and found it appallingly apt. I think that would definitely be the result of any global or even national anti-CO2 policies: vast numbers of people would die. Democide means not the targeted killing of ethnic groups (genocide) or political enemies (politicide), but is a term that covers the wholesale and intentional killing of a country’s population by its government.
It might also mean the results of the mid-term elections. An enormous Demo-cide in the House, especially.
