Why Has Singapore Become Hotter and Drier in Recent Years?
As we find ourselves amidst a heatwave, one can't help but wonder why Singapore seems to be experiencing such extreme conditions. It's not just my husband who feels the intense heat; it's a common sentiment among the residents. Every day, it feels like the temperature is pushing the limits, and sometimes even the official measurement of 33 degrees Celsius seems inadequate to explain the oppressive heat.
Factors Contributing to the Heatwave
The heatwave in Singapore can be attributed to various factors, including the climate phenomenon known as La Ni?a. This natural event often leads to higher temperatures and lower humidity levels, creating a perfect storm of conditions that make the weather feel even more unbearable. Currently, we are experiencing the effects of La Ni?a, which has resulted in a milder winter than usual.
Usually, at this time of the year, the temperature would be significantly lower. However, things have changed dramatically. What does this mean for Singapore? It means that the heat is intense and prolonged, making it challenging for people to enjoy the outdoors without feeling the strain of the scorching heat. This is evident in the fact that temperatures that used to be around 16 degrees Celsius now sit around 22 degrees Celsius, a significant jump that makes the air feel clammy and oppressive.
Understanding Climate Change in Singapore
The phrase 'climate' encompasses a wide range of factors that affect the weather patterns, including global temperatures and humidity levels. The term 'climate change' specifically refers to these evolving patterns, which are causing prolonged periods of high temperature and humidity in Singapore. According to meteorologists, the average afternoon temperature in Singapore is expected to remain consistently around 30 degrees Celsius or higher, adding to the discomfort of residents.
The Vicious Cycle of Heat and Humidity
Given the consistently high temperatures and humidity, the effects are felt not just in the afternoon but throughout the day. The heat leads to increased sweating, but the humidity levels prevent sweat from evaporating efficiently. As a result, people like myself are forced to constantly seek relief in air-conditioned spaces. The sweat clings to the skin, creating an uncomfortable and sticky sensation.
To illustrate this vicious cycle, let's consider a typical day. The high temperatures cause excessive sweating, and the high humidity prevents that sweat from evaporating. This creates a constant state of discomfort, making it necessary for people to frequently shower or seek refuge in air-conditioned environments. While these conditions might not last forever, the ongoing trend towards higher temperatures and lower humidity is a concerning sign of a changing climate.
Conclusion
As Singapore continues to experience the impacts of climate change, it is crucial to understand the underlying factors contributing to the current heatwave. La Ni?a, a natural climate phenomenon, is one of the main culprits, but the broader issue of climate change poses an ongoing challenge. While the heat may not always last, the need to adapt to these changing conditions is a reality for Singapore's residents. By staying informed and making conscious efforts to reduce our carbon footprint, we can work towards mitigating the negative impacts of climate change.
