In 2016, all except 2 UN countries (Nicaragua and Syria) signed the Paris Agreement. They agreed to set goal for greenhouse gas emission reduction, in an effort to achieve the mission of keeping the increase of the global average temperature to well below 2 °C above pre-industrial levels.

The map shows the distribution of greenhouse gas emission among countries. United States and China account for the highest proportion of emission. Unfortunately, in 2017, United States announced its withdrawal from the Paris Agreement. Although such withdrawal notice could only be made 3 years after the Agreement came into being, and not take effect a year thereafter (2020), the move has already affected the morale of the international community..

Global warming has far-reaching impacts. It could lead to iceberg cessation, sea level rise and water temperature increase. The climate change could affect the ecosystem and intensify the uneven distribution of precipitation, and subsequently affects food production and price. As ecosystem and temperature are affected, vector-borne infections could become more widespread, causing illnesses and deaths. In fact, besides efforts at country level, we as individuals can also contribute to the control of global warming in our daily life. Let’s reduce electricity, fuel (coal and oil) and paper usage, and take the mass transit system. We can protect the environment..!

地圖顯示各國的相對排放溫室氣體百分比。其中美國及中國 佔最大百分比。令人惋惜的是,美國於2017年宣佈退出協定。雖然根據協定要求,簽約國須在協定生效滿3年後才能提出通知,並在通知一年後才能正式生效(2020年),但消息對於國際社會的整體士氣有一定影響。

全球暖化的影響深遠,首先冰川會消融 、海平面會上升及水溫會升高 。生態系統 會因氣候變遷而受影響,加上降雨量不圴而導致的旱災,都會造成農作物失收,影響糧食產量及價格。此外,全球暖化令以蚊作傳播媒介的傳染病更廣泛地散布,危及生命。事實上,除了國家層面的努力,大家亦可在日常生活中出一分力,減少用電、燃料 (煤、油)及紙張、盡量乘搭公共交通工具。保護環境,我做到!
