Climate change is considered the greatest threat that Earth has to counter in this century. Due to intensified human activity and unsustainable use of the planet’s resources, the percentage of carbon dioxide in the atmosphere has increased while the planet’s ability to absorb the excess carbon dioxide has decreased due to the elimination and degradation of natural carbon sinks such as forests and oceans. This imbalance in the atmosphere has led to increased global warming over a long period of time, and scientists have confirmed the existence of climate change.
In the past decade, extreme weather events have been triggered all over Sri Lanka, taking place more and more frequently and intensely. The severe drought conditions in districts such as Jaffna and Polonnaruwa have continued unceasingly since 2016. More recently, the intense floods experienced in May-June 2018 in most Southwestern and Central regions of Sri Lanka saw the displacement of tens of thousands of families.
