People like you LOVE to point fingers at America as being the main one here causing this.
1) back in 1992 when we found out about this, Europe's yearly total emissions were actually MORE than America's and had been for a LONG TIME. Europe's gas tax is what brought down Europe's emissions, not the poltics.
2) During the time of W, America did NOT cut back, however, for the last 6 years, we have cut back because of 3 reasons:
a) cheap nat gas here, combined with cheap wind. Both of these are much cheaper to do than coal.
b) W delayed regulations on mercury until 2017. Now it is taking effect and many coal plants have shut down, with more to come.
c) O's regulations are taking hold and is preventing future coal plants, as well as some nat gas plants, and leading towards more AE, along with nukes.
3) America's emission are today BELOW 15%, and dropping. China's emission are estimated at around 33% of global emissions, rising, and that is without data from OCO2.
4)
OCO2's emissions PROVE that China's emissions are much higher than anybody elses.
5) Not only is China's yearly emissions double of America's, but as of THIS YEAR, their TOTALED emission from 1850, is greater than America's.
6) And in terms of total emission for the last millennium, China's is greaters than Europes, but both are MUCH MUCH greater's than all of the America's COMBINED.
Yet, idiots like you will focus on 1 nation, rather than focusing on the nation that accounts for more than 40% (OCO2's date is going to prove that China has lied about their real emissions), or the fact that Europe's total emissions is much much higher than America.
