This issue is largely a technical interest as now in 2011, there has been statistically significant warming since 1998.
China's Coal consumption has massively increased and almost equals the rest of the world and as China's Coal consumption is expected to double in less than twenty years efforts to mitigate Carbon emissions in the rest of the world seem quite pointless.
The idea that China will somehow alter it's Coal consumption in regards to mitigating Global warming is shown to be a fallacy as China has trebled it's coal use over the last ten years, a period in which Global warming concerns have been at their highest.
Chinas consumption is of such a level that it effects the rest of the Globe, as Greenhouse gasses are not confined to the entity that created them.
