Attributions of floods/cooler along the Yangtze River Valley and droughts/warmer in North China for the last 25 years have been reviewed in this paper. Both natural climate variability and human activities are considered. Some stronger evidences contributed to the natural climate variability, such as decadal and interdecadal variabilities of East Asian summer monsoon, the periodicities and transitions of rainfall and temperature changes in China, abrupt climate change, NAO, AO, AAO, ENSO, and snow cover. The signals produced by the human activities such as greenhouse gases and "brown clouds" likely play the role for the patterns. But the physical feedbacks and mechanisms still keep ambiguous and vague. More researches should be carried out in future to solve this issue.
