Read the IPCC report on climate change which warns of increasing temperatures, extreme heatwaves, droughts and flooding.
Almost every nation on Earth signed up to the goals of the Paris climate agreement in 2015. The pact aims to keep the rise in global temperatures well below 2 degree Celsius this century and to pursue efforts to keep it under 1.5 degree Celsius.

What is to be blamed for the decline in the water level in
Southeast Asia’s largest freshwater lake, Tonle Sap in Cambodia?Station readings at the lake recorded a level of just 3.86m on 31 Aug, 2021 which is nearly 1m lower than in 2020 and about half the normal average at this time of the year.Upstream dams, constructed along the upper Mekong river in Laos, Thailand, Myanmar and China - where the river is known as Lancang - withholding water are a contributing factor to the lower levels of flow into the lake.
Data from the Mekong Dam Monitor, an online platform that tracks indicators in the Mekong basin, shows that more than 12 billion cubic metres of water have been held back by 45 upstream dams since early July.Climate change is also creating havoc with the timing and intensity of the monsoon season, further disrupting the natural behaviours of the lake system and decimating agriculture in Cambodia.How much hotter will it get for Singapore?
While humans can adapt to this with air-conditioning and shade, our native flora and fauna cannot and the impact of a prolonged heatwave will be detrimental.
A warmer atmosphere can also “hold” more moisture - about 7 per cent more per 1 deg C of warming. This can produce more intense rainfall events.
How can climate change be mitigated in Singapore?
Singapore Green Plan 2030
Urban heat island effect occurs when natural land cover is replaced by urban surfaces that absorb and trap heat, such as buildings and roads. Studies have shown that this has caused temperature differences of up to 7 degrees Celsius between urban and less built-up areas in Singapore.
In the first half of the year, urban heat island effect has resulted in eastern areas such as Marine Parade and Changi to bore the brunt of the heat compared to other parts of Singapore, according to climate maps from MSS. In some months, the difference was nearly as much as 4 degrees Celsius.

Several buildings in Tampines central may soon be retrofitted with a cooling system that is more energy efficient. This can lead to 17 to 18 % reduction in electricity consumption. Known as distributed district cooling, the proposed network for Tampines involves having the existing cooling systems of selected buildings produce chilled water to serve the building and others around it.
The buildings will all be interconnected via insulated pipes that can distribute and circulate the chilled water in a closed loop.Greener system of cooling buildings pave the way for more eco-friendly towns. Sustainable towns and districts are essential for Singapore to meet our sustainability goals under the Singapore Green Plan 2030.
A district cooling system can be likened to a giant air-conditioner that can cool an entire district of buildings rather than just individual ones. Chilled water is generated in a central cooling plant before being piped to various buildings through an underground network to provide air conditioning. Warmer water is then circulated back to the cooling plant, so that they can be chilled again and redistributed to buildings. One area that has implemented a district cooling system is Marina Bay. Designed and operated by SP, the underground system serves 16 developments in the area, including Marina Bay Sands, the Marina Bay Financial Centre, as well as One Raffles Quay. By centralising the production of chilled water, about 25,000 sq m of prime land space was freed up for other uses, as buildings did not have to build their own chiller plant.
