港去年平均氣溫 創135年新高

【兒童報訊】天文台指本港二○一九年的平均氣溫是一百三十五年來最高，全年只錄得一日寒冷天氣，是有紀錄以來最少寒冷日數的一年。環保人士認為，這印證香港存在氣候暖化，將衍生多項環境問題，如城市涼風逐漸減少，社區內污水增加，容易滋生細菌。

The Hong Kong Observatory revealed that the city's average temperature in 2019 is the highest since 135 years ago. There was only one day of low temperatures, which was the fewest since records began. Environmentalists believe this verifies that Hong Kong has signs of global warming. That creates various environmental problems such as a decrease in urban breezes and an increase in the community's sewage, which would stimulates bacterial growth.

小知識
寒冷天氣
    當天文台預測市區最低溫度將跌至12度或以下，便會考慮發出寒冷天氣警告。溫度只是其中一項指標，天文台亦會考量實際風速、相對濕度等因素。
