The first trumpet sounded, and a third of the earth was burned up, along with a third of the trees and all the grass. Rev 7 The first angel blew his trumpet, and there followed hail and fire, mixed with blood, which were thrown upon the earth. This would be something that only affects one-third of the trees, plants, and all the grass. The description from Rev. 8 is that hail and fire mixed with blood are the first of the calamities, and its description is almost identical to the description of the angel pouring out the censor on to the earth.
This is the first of the calamities, and it is a supernatural event. One third of the earth is burned, but which third? In Rev. 15, this event causes the people who have received the mark to develop sores. That makes it the area controlled by the Anti-Christ; one third of the trees and all the grass are burned up. That's a ninth of the trees on earth and one third of all the grass. Wow, is that going to use up some carbon credits? Is this the cause of the darkness that comes upon the earth in future calamities? It does not sound like a natural occurrence but a supernatural one. It will be interesting to see how the news media explain it. Another climate event that requires even more controls?
