While very visual appealing. And the designer made reasonable efforts to collect valid data. There is a problem in this graphic: It displays based on countries and not on per captia. This maps somehow leaves the visual impression that the problem lies in Asia (China, India, Russia), while these countries are really big polluters the problem is the per capita emission of the USA. So the visual map misleads a bit. That just my biased opinion. But maybe a mash up with http://www.sasi.group.shef.ac.uk/worldmapper/index.html would be interesting here.

I think the map itself is visually appealing.

For reasons that cannot and will not be explained breathingearth.net has been blocked here in Thailand.

This has taken the paranoia of the current government (junta?)to new levels where any sort of comment/website that does not fit into their thaicentric view is seen as a threat and like breathing earth is blocked.

Breathingearth a threat? you have to be joking....

I am a writer and much of my stuff deals with the dual threat of governments and the disaster that our economic system has gotten us into. Check out http://sites.google.com/site/greggthought/ Every organism has to 'make a living' including humans.
