All we seem to hear about right now is the drought and forest fires all over the world; but some scientists are saying that our sun is going to go into sleep mode in about 15 more years. Apparently, the sun does this about eery 400 years, and the last time was in the 1600's. The youtube video that explains how it works , also has statistics for what happened the last time around. Millions and millions of people either starved or froze to death all over the world when it happened. Now, to be honest, we have advanced a long ways since then, and we can pretty much grow year around somewhere, and ship food as needed. However, we also have a lot larger world population than we had 400 years ago, so a lot more people to have to be fed, and most of them already living in countries that are too poor to buy food, and already stricken with famine. Regardless of our industrial development andtechnology; I think that this will be a hard time for the whole world when it happens.
