Fracking is shorthand for hydraulic fracturing, a type of drilling that has been used commercially for 65 years.
The climate of Shanghai in december is bad. The weather in december in Shanghai is relatively dry (with 67mm of rainfall over 7 days). The weather's not getting better compared to the previous month since in november there is an average of 59mm of rainfall over 6 days. The climate is quite cold here the month of december, but it is endurable when dressing cosy.
Winters in Shanghai are about as cold as winters in Seattle (but quite a bit less rainy). In southern China, it's a bit hard to say. In the mountains of southwestern China, winters are mild to cool, but now very cloudy and almost always without any snow, while in lower southeastern China, winters are warm and humid, like in Florida.
