Humans cannot change the oscillating output of a certain nearby star. That is the source of the minuscule changes to the Earth's temperature underway, not human behavior. Contrary to the hysterics of so-called climate scientists (who have been shown, time and time again, to have cherry-picked their data or invented it entirely; aka "data fraud") there is no evidence humans are changing the temperature of the planet.
That being said, China seems to have no regard whatsoever for gross pollution of the earth, skies, and seas. A separate issue but worth addressing.

NASA has fiddled with the data: `From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.”`
If you're not willing to trust data, that makes you religious, not scientific.
