Spatio temporal patterns of different period climate warming rate in China (1961—2014)

Different statistical methods and data from 534 meteorological stations were used to diagnose
 variations in average annual temperature in China from 1961-2014. Time series of annual average temperature
of China presented an increasing trend. Decade trend in annual average temperature was found to be different,
with the following characteristics: decrease- increase- increase- increase- decrease. Annual average temperature
 showed fluctuation characteristics with different time scales: 2-6, 20, 40, and 60 years. An abrupt change was
found for 1998: climate warming stopped. For spatial distributions, annual average temperature in all meteorological stations showed increases from
 1961-2014. Meteorological stations with increasing trend on decade
scales compared with the whole study period accounted for 2.6%, 32.9%, 78.8%, 86.0% and 11.2%
respectively. Especially the 1960s and 2000s showed significant decreasing trend in large areas. Annual average
 temperature showed significant increasing trend from 1971-2000 in large areas. Either increasing or decreasing
trend, northeastern China and Qinghai-Tibet plateau showed significant variations in spatial patterns. From
2000 annual average temperature in China has showed marked stagnation, although carbon dioxide emission
showed sharp rise in the same period. Different theories could possibly explain the stagnation in climate
warming, although many uncertainties await further investigation.
