The atmospheric greenhouse effect is a well known natural phenomenon, mostly caused by atmospheric water vapour, that keeps our planet warm and habitable whereas (anthropogenic = human-made) global warming refers to a small extra greenhouse warming (0.5-1 C/33 C; 1-5 %) allegedly arising from an increase in atmospheric concentration of the minority greenhouse effect gas CO2 (carbon dioxide) – the later increase in turn possibly arising from fossil fuel burning.
