These alarming disasters are not aberrations. The climatic changes brought on by global warming--record-setting rainfalls, typhoons, heat waves--have made themselves apparent repeatedly in recent years. The blame for warming climates falls squarely on humans, who produce greenhouse gasses, such as carbon dioxide.
這些駭人聽聞的災難不是特例，隨著地球暖化帶來的氣候變異──破紀錄的暴雨、颱風、超級熱浪──近年在全球各地一波波上演，而論氣候暖化的罪魁禍首，由人類大量製造的二氧化碳（CO2）等溫室氣體難辭其咎。
