A Pareto Diagram

In statistics, and its manufacturing cousin Statistical Process Control, a Pareto Diagram is a chart that graphs problems or errors in a process, by frequency of occurrence.  The bars on the graph are ordered by frequency, meaning the most common problem is shown first, followed by the next most serious problem, all the way down to the smallest problem.  The purpose of such a chart is to show you where you get the biggest bang for your "fix a problem" buck--in other words, you always attack the biggest problem first.

If your global warming hysteria doesn't address China, you're not serious about the climate so-called problem that you claim to care about:

Since 1965, no country has put more carbon dioxide into the atmosphere than the United States. The 264 billion metric tons of carbon dioxide the U.S. has emitted to the atmosphere represented 22.5% of global emissions during that time, and was well ahead of the cumulative 216 billion metric tons from the European Union (EU). In second place among countries was the 188 billion metric tons emitted by China...

China's emissions passed those of the U.S. in 2005, and by 2012 had surpassed the combined contribution of both the U.S. and the EU. Should recent trends continue, China will be responsible for the most atmospheric carbon dioxide in less than 20 years.
