Thanks for your views Anurag.. I want it in detail, as I want to share this with my office employees & make them understand the impact of global warming & how can we avoid it by changing our approach.

Global warming is a natural phenomenon. The world has warmed and cooled ever since time immemorial. Problem is, you can't tax a natural phenomenon!

I really wonder why such "ready-made" stuff are being asked in this forum. With little googling and research, immense material can be collated.
Please open up google, and type in the search box: global warming filetype:ppt.
The results would amaze you!
Regards.
