I'm going to tell you a little secret. In what is known as the "Maunder Minimum," Chinese crop production dropped, and Korean crop production also dropped. This caused major problems for their dynasties, as they collapsed, being unable to fees their people. Same thing with the Wolf Minimum and the Dalton Minimum. Chinese dynasties collapsed.
A Grand Solar Minimum has begun, and I encourage you to look up the information, the history of these events and what happened. This will explain why both North Korea and China have to make deals. Simply put, they have to feed their people. Search this "Maunder Minium Chinese Dynasty Collapse" and LEARN THE SECRET the global warming con men never want you to know AND the secret reason China and N. Korea MUST make deals!
I know you never heard this before, because I'm the only one who would tell you. I'm sorry, but I need to inform you that you had better prepare as well, because it can affect us over the next 30 years right here, too. We will just do somewhat better, because we will still have growing zones for staple grains. It will all shift south, though. Winter wheat losses are all ready taking place.
I'm going to let you do the research. Start with the search I gave you, so you can know the facts that the mainstream media will absolutely never tell you, mostly because they don't know, because they don't research much of anything. They are repeaters, not reporters. They also don't get to report truth like this. They are not allowed to report truth conflicting with global warming.
