Global warming caused by emission of carbon dioxide (CO2) and other green house gases used to be a controversial topic with some scientists claiming that the world's climate is definitely getting warmer because of emission of carbon dioxide and other green house gases while others says it is a just a natural cycle of warming and cooling of the world's weather. Evidences are piling up to support those of the first opinion with polar ice, glaciers, mountain snow peaks melting (including that of the highest mountain in the world - Mount Everest), climate of countries changing, some say hurricanes getting more frequent and more ferocious, birds and animals migrating further north to warmer climate, etc.
One thing I know is my country is now hotter for I sleep topless and without fan or air conditioning. Anyway, many are hoping governments will do something about it, and for that it is good to know which country are emitting more carbon dioxide, the major green house gas. So here is an excel file ranking countries by its carbon emission. The figures are taken from Wikipedia - List of countries by carbon dioxide emissions by carbon dioxide emissions.
