Not concerned. The earth has been around for billions of years, right? During that period, science has shown that the earth has gone thru periods of deep freeze as well as hot arid conditions. Few argue these points. The period of these changes is longer then these snippets of photos.
Moreover, no people were around way back then. Who was to blame? (must have been the republican dino's
)
Lets keep in mind that when a big volcano erupts, it puts out more toxic gas then all the exhaust fumes produced from autos for decades. Sure we should do what can to stem polution as technology permits but you need see the big picture. Everthing is NOT mankinds fault and it is esp not G%$%$%$%$'s fault.
The time scale of those photos are so small (100 years maybe) that no long term trend can be established. The earth clearly has changed in cycles for billions of years there is NO evidence that anything has changed. So, over the last 100 years the earth is warming....so what? that does not mean it will continue! Perhaps, If you extrapolate from a tiny slice in time to the future, things could look ugly. This is like saying, my child grew 3" this yearand gained 20#...this doesn't mean that he will be 17.5' and 1400# when he is 70 years old.
THis is ***exactly*** the kind of "science" you are refering too. It is aimed at specific people to scare for various reasons as well as for political reasons.
BTW, per our productivity or output, we produce FAR less pollents then most of the world. Sure if you don't MAKE anything you can have less waste.
