>If only China and US could get their shit together....
If people in the US are still consuming multiples more than people in other societies, then a decrease of 36% means the US still does not have their shit together. Presumably, zahlman's response of pointing out the 36% decrease was a refutation of fHr's claim for China and US to get their shit together.
Although, also funny is that the US's 36% decline is partly (significantly?) due to exporting CO2 emissions from manufacturing to China, but that applies to the rest of the world too.
