China Warns Global Warming Will Become Extreme!
 

China's gross domestic product is between 400 and 1,000 US dollars per
capita, but its pollution levels are similar to those in western countries
with a GDP per capita of between 3,000 and 10,000 dollars.

Sixteen out of the world’s 20 most polluted cities are found in China.

Do the math:

In the US there are about 745 vehicles per 1,000 persons.
In China there are about 8 vehicles per 1000 persons.

Today
China pop. 1,300,000,000 * (8/1000) = 10,400,000 cars
US pop. 296,555,646 * (745/1000) = 220,520,000 cars

FUTURE Year 2025 ( est. pop. )
China pop. 1,500,000,000 * (745/1000) = 1,117,500,000 cars
US pop. 349,000,000 * (745/1000) = 260,000,000 cars

Stick your Kyoto Treaty up your ass!
