Unhealthy PSI levels in North of Singapore
At 7pm on 27 February 2021, the Pollutant Standard Index (PSI) in the North region of Singapore had reached unhealthy levels (peak: 108). PSI is calculated based on six pollutants - PM2.5, Sulphur dioxide, Carbon monoxide, Ozone and Nitrogen.
Ozone is formed when other components of the air, nitrogen oxides and other volatile organic compounds, react under specific environmental conditions, including the presence of sunlight

Predicting Earth's future with technology
Scientists are building a highly accurate digital simulation of planet Earth to provide reliable information about extreme weather and climate change. This new project, known as Destination Earth, will bring all environmental factors together alongside human actions to “depict the complex processes of the entire Earth system”.
Ocean Acidification
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent. This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.
Global Temperature Rise
The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 35 years.
The Antarctic Peninsula is setting heat records. They won’t stand long.
On February 6, Argentina’s Esperanza Base clocked a temperature of 18.3 °C, beating the station’s previous high record of 17.5 °C. Two research estimates that sea levels could rise by 2100 downward, suggesting that Antarctica could contribute somewhere between 3 to 16 inches to the world’s oceans.
Shrinking Ice Sheets
On February 6, Argentina’s Esperanza Base clocked a temperature of 18.3 °C, beating the station’s previous high record of 17.5 °C. Two research estimates that sea levels could rise by 2100 downward, suggesting that Antarctica could contribute somewhere between 3 to 16 inches to the world’s oceans.
Sea levels are rising at unprecedented rates.
Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century and is accelerating slightly every year. In fact, an estimated S$5 billion Coastal and Flood Protection fund will be implemented to tackle 'significant' risk of rising sea levels in Singapore.
Extreme Events
The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950.
Decreased Snow Cover
Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over the past five decades and that the snow is melting earlier.
Climate change & Food security
Despite efforts to improve food security especially in developing countries such, much work has yet to be done and climate change is making food insecurity worse.
Click to find out more about how food security is negatively affected by climate change.
Habitat loss
Climate change such as shrinking ice sheets and rising temperatures often lead to loss of habitat which causes more and more species to go extinct.
The rate of biodiversity loss is increasing rapidly.
