The effect of global warming is like the effect of smoking. Both of them has no immediate impact. The impact of smoking will slowly but sure will reduce of your quota to live. Maybe the impact of global warming / climate change will not immediately or directly affecting the present generation but I believe it will inherit a huge disaster (like time-bomb) for the next generations, that is our own descendants.
Partly of human habit is likely not concerned to the matter that has no fatal impact immediately, like discard old batteries in the gutter, the use of bombs or potassium cyanide to catch fish, as well as drunk and smoking habits.
I'm aware that this post is only a very very small contribution to raise the awareness of global warming issue.
I have inspired by Neil who already create a special sub-page on his blog with the title "Climate change is real, real, real…". Three times for "real" as you see.
