The Growing Threat of Climate-Driven Health Risks in Singapore and the Tropics
Singapore, a tropical city-state in Southeast Asia, faces escalating health challenges from climate change, including intensified heat stress, surging vector-borne diseases like dengue, worsening air pollution, and variable water quality. In 2025, Singapore recorded 29 days of high heat stress, up from 21 the previous year, partly due to expanded monitoring but underscoring rising temperatures. Dengue cases, though lower at around 4,000 in 2025 compared to prior peaks, are closely linked to warmer, wetter conditions that boost mosquito breeding, with climate warming contributing to 18-20% increases in incidence regionally. Air pollution, the sixth leading health risk in Singapore, could cost Southeast Asia up to $600 billion by 2050, with over 90% of the population breathing unsafe air per WHO standards. These interconnected risks highlight the urgent need for targeted research in higher education institutions like Nanyang Technological University (NTU) Singapore.
NTU Singapore Unveils the Centre for Climate Change and Environmental Health
On April 15, 2025, NTU launched the Centre for Climate Change and Environmental Health (CCEH), a pioneering interdisciplinary facility dedicated to studying and mitigating tropical climate health risks. Officiated by Senior Minister of State Dr Amy Khor at the Experimental Medicine Building, the centre addresses under-researched tropical vulnerabilities, where high humidity, monsoons, and transboundary haze amplify impacts. Led by Director Assoc Prof Steve Yim, an expert in air quality and climate modeling, and Deputy Director Assoc Prof Sanjay Chotirmall from NTU's Lee Kong Chian School of Medicine (LKCMedicine), CCEH integrates atmospheric science, medicine, environmental engineering, and data analytics.
The facility leverages AI, environmental sensors, remote sensing, and advanced modeling to predict and counter risks to respiratory, cardiovascular, and mental health, particularly for vulnerable populations like outdoor workers and the elderly.
Pillar 1: Tackling Air Quality Degradation in a Warming Climate
Air quality forms CCEH's first pillar, focusing on how climate change exacerbates pollution through intensified storms and haze. Recent NTU research shows air pollution 'supercharges' Southeast Asian storms, potentially costing the region $600 billion by 2050 and leading to 36,000 avoidable premature deaths if unaddressed. In Singapore, pollution ranks as a top health risk, contributing to heart disease and respiratory issues, worsened by urban heat islands and transboundary sources.
- Transboundary haze episodes, like those studied in 2025, link to increased hospital admissions.
- AI-driven forecasting models predict PM2.5 spikes during El Niño events.
- Synergies with heat: Combined exposure multiplies health effects beyond individual hazards.
CCEH's work builds on Prof Yim's projects with NUS and Stanford, modeling global heat-pollution interactions.Learn more on NTU CCEH air quality research.
Pillar 2: Addressing Extreme Heat and Synergistic Vulnerabilities
Extreme heat, CCEH's second pillar, examines heat stress amplified by humidity—the 'feels-like' temperature in Singapore often exceeds 40°C during peaks. 2025 saw record heat stress days, with climate change adding 122 dangerous heat days in 2024 alone. WHO data indicates 45% of global heat deaths occur in Asia, with Singapore's urban density heightening risks for workers and children.
Research highlights synergies: Heat plus pollution increases mortality more than sum of parts, informing updated guidelines. NTU simulations project El Niño reducing life expectancy gains by 2.8 years by 2100, with trillions in losses.
Pillar 3: Securing Water Supply and Quality Under Climate Variability
The third pillar targets water challenges: droughts strain supply while floods risk contamination. Climate variability has increased Singapore's annual rainfall by 83mm/decade, overwhelming drainage yet causing dry spells. CCEH studies waterborne diseases like diarrheal illnesses, linked to warming waters favoring pathogens.
- Extreme rainfall events spread contaminants, raising cholera/salmonella risks.
- Droughts impact NEWater production, vital for 40% of supply.
- Modeling predicts tropical-specific shifts in microbial ecology.

Interdisciplinary Teams Powering CCEH Innovations
CCEH unites NTU's top talents: LKCMed for clinical insights, Asian School of the Environment (ASE) for climate modeling, Earth Observatory of Singapore (EOS) for geohazards, SCELSE for microbial risks, and NEWRI for water tech. This synergy fosters breakthroughs like AI-enhanced exposure assessments.
Prof Yim's remote sensing expertise complements Chotirmall's respiratory research, training PhD students over five years for policy impact.
Flagship Projects and Real-World Case Studies
Early CCEH outputs include CARE-ASIA, a multi-country platform analyzing heat-pollution in Asian cities, expanded via Tsao Foundation philanthropy to include Jakarta. Another: Dengue projections under warming, aligning with Wolbachia releases covering 50% households by 2026, reducing infections 75%.
| Project | Focus | Impact |
|---|---|---|
| CARE-ASIA | Regional heat-air data | Policy for 9 countries |
| Storm Supercharge Study | Pollution-climate interaction | $600B savings potential |
| El Niño Mortality | Long-term life expectancy | 2.8 years loss avoided |
These demonstrate CCEH's translational research. Build your CV for climate research roles.
Strategic Partnerships and Regional Leadership
CCEH partners with A*STAR, Imperial College London, and CARE-ASIA members (India, Indonesia, etc.), plus philanthropy like Tsao Foundation. WHO contributions and 2025 meetings position NTU as SE Asia hub. Ties to NUS's CAWRAS enhance tropical weather science.
Singapore's RIE2025 funds such efforts, aligning with Green Plan 2030. For faculty positions, visit university jobs in Singapore.
Government Synergies and Policy Influence
Dr Khor emphasized CCEH's role in Singapore's adaptation, complementing Wolbachia and 2026 Heat Resilience Office. Builds on Third National Climate Study projecting wetter/drier extremes. Evidence informs NEA haze responses and MOM heat guidelines (10-min hourly breaks).
Building Future Talent in Climate-Health Research
CCEH trains PhDs and postdocs, publishing in high-impact journals. Amid SG's research boom, opportunities abound at NTU/NUS for interdisciplinary careers. Check research assistant jobs.
