In Colombo, residents like Fathima Rinoza struggle with unbearable midday heat.

The city’s rapid urbanization has led to a dense building landscape that traps heat, exacerbating the effects of rising temperatures. This situation forces many to rely on expensive air conditioning or seek alternative cooling methods, such as passive cooling techniques, which can be costly to implement and maintain.

Passive cooling involves designing buildings to naturally regulate temperature without mechanical systems, but it requires significant upfront investment that many cannot afford.

The long-term vulnerability of Colombo’s infrastructure to increasing heatwaves is evident. Without widespread adoption of sustainable cooling solutions, the city faces a future where energy costs soar and thermal comfort becomes a luxury.

What is the long-term climate outlook for this region?

Colombo must invest in urban planning that prioritizes green spaces and passive cooling designs to mitigate rising temperatures. Failure to do so will lead to increased energy consumption, higher costs, and a decline in quality of life.

The outlook is negative without significant changes.
