yes, the climate is going to change, but not to an enormous extreme, and yes it is going to affect our way of life, but I have to disagree with you about the extreme of your prediction on our society.  However, I do believe that we will suffer.  We are human and we will survive this with stride.  That said, there are events, tragedies and starvation occurring as I write this.  This is nothing new.  Our world will always have suffering, but it will also be plentiful in some aspects and you don't have to have prediction abilities to know this because it is on the news everyday.

What you are seeing is very true, but know one knows which way it will go, the point is are you a survivor are ready to survive, and live your life in a very simple matter, and able to teach all those around you, how.
So take a deep look into yourself and answer these questions.

It is unlikely that the rising pressure on the world economy will allow oil hungry and developing nations to last till starvation.  The need to take oil by force will push the world leaders into manufacturing reasons to attack and occupy oil rich nations of lesser Military power.

The retaliation of the oppressed peoples of these conquered nations will be left with no options but to attack in the most sacrificial methods at their disposal.  Nuclear suicide bombing will strike the heart of large cities like New York and Seattle before it’s over.
