I think everyone should read it, just to realize the desperate need of the change in our behaviour. And yes, maybe you won't experience those tragic consequences.. but do you want your children/grandchildren or somebody else's to? After you read it, I don't think you would wish your worst enemy that destiny.
I don't want to sound like a preacher, but if you don't fully understand what global warming is or have some trouble understanding why you should recycle/use less electricity or energy at home/take the bike instead of the car and so on.. I encourage you to read it, then you will have enough explanation.
