Enhancement of the warming trend in China

The 1998 temperature averaged for the globe is the highest on record. Annual mean temperature of China in 1998 is +1.38 degrees C above the normal, which also labels 1998 the warmest year since 1880 for China. Additional ice core delta(18)O and tree ring evidence shows stronger upward trend (of 0.50 degrees C/100 years) than ever estimated based on temperature observations in eastern coast region only during the last hundred years. Enhanced warming trend has occurred in most eastern Asia, the remarkable trend is making the middle-high continent of eastern Asia one of the rapidest warming regions in world during the last 2 decades. And the warming time series in China indicates a sinusoidal variation over the past hundred years and is different than for the global average.
