I think it was the Krakatoa eruption that sent so much crap in the stratusphere that it cut sun light to the earth.

 

This cause trunciated growing seasons all over the earth and the agriculture at the time were not sophisticated enough to make changes fast enough to avoid starvation.

 

IN fact this change in climate is probably a major player in the fall of several goverments.

 

I am not sure but I think that this was around the time of the french revolution and the starvation levels pushed the population forward into revolution. Remember the "Let them eat cake" I think that is why, the population was trying to get bread. I am not saying that revolution was not going to happen anyway but without the pressure caused by the missed crops and starvation maybe it would have been put off for a few years. Maybe the great thinkers and agitators would have had to avoid the french goverments agents longer before the Bastile was stormed. If that had happened how many of the Revolutionist would have survived to see the day and without them do you really think it would have happened? France could have ended up much like England. Maybe less blood would have fallen in the streets of paris.

 

(I could be full of shit on that one but it seems right)

 

With the weather changes we are seeing it might be important that we study the effect that weather has had on goverment and civilizations. These changes historically haven't actually been over a great deal of time. Long term changes are easily absorbed and adjusted for. A five to ten year change can be disasterous.

 

I think that is probably why you posted the question.......

What do you think would happen if america had two consecutive crop failures?

I grow my own crops and can them..what you say is just more people to shoot or keep off my 80 acres every one else will go hungry...

C is correct
