Who should take responsibility for carbon dioxide emissions?

There was a report on BBC News today about a phenomena taking place in India. The glaciers are melting at a much faster rate and they are a potential threat to the people living near them. Floods could possibly occur. What is causing this? Apparantly, it is the "rich nations" which are causing this. The average carbon dioxide emission in India per person is estimated at one ton per person per year. In Europe, we are looking at figures of ten tonnes per person per year. And in other more industrialised countries such as America, we are looking at twenty tonnes per person per year. So I decided to check it out. And guess what I found! http://www.aneki.com/dioxide.html

Singapore is sixth on the list. Each person emits about seven tonnes of carbon dioxide per year. We are such a small country and yet we are emitting so much CO2. Something is definitely wrong.

Back to the point. So who is to blame? The rich countries enjoy the luxury while the poor countries suffer at the hands of Mother Nature. What can we do?
