The relation between the growth of economic and carbon emission is a significant positive correlation, and economy scale has increment effect to carbon emission.
经济增长与碳排放量存在显著正相关关系，经济增长对碳排放变化具有增量效应；

The research has shown that the CO2 emission in China has continuously increased and the sum of positive radiative forcings produced by greenhouse gases is responsible for climate warming.
研究表明，中国的CO2年排放量呈不断增加趋势，温室气体正辐射强迫的总和是造成气候变暖的主要原因。

Here therefore we have a true radioactivity which is made evident by the emission of positive electrons.
