Climate change is the long-term changes in the climate pattern that is attribute directly to the increase in global temperature caused by human activities ie. the burning of fossil fuel which releases Greenhouse gas (GHG). The GHG accumulates over the Earth’s atmosphere, where it traps the radiation (heat) from the sun like a blanket and prevents it from escaping the Earth. This traps heat and makes the Earth warmer, a phenomenon known as Global Warming. These changes will alter the weather patterns, leading to multiple climate-induced events such as drought, flash flood and sea level rise.

Globally, the warming of climate system will consequently lead to the increase of global air temperature, ocean temperature, melting rate of ice glaciers and the increase of average sea level.​
