Shaw C. Liu, director of the Research Center for Environmental Changes, Academia Sinica, notes that in terms of absolute values, the increase in temperature (1.5oC) of Taiwan's major cities over the past century is around double that of the Northern Hemisphere as a whole (0.7oC). This tends to indicate that "global warming" is only a backdrop to the main urban warming phenomenon: the heat island effect.
中央研究院環境變遷研究中心主任劉紹臣指出，在增溫的絕對值方面，過去百年來台灣都會區的增溫（1.5℃）比北半球增溫（0.7℃）高出約 2 倍，顯示「全球暖化只是大背景，各國主要城市的增溫現象，明顯是受到熱島效應的影響。」
