NTU Singapore's Bold Step into Climate-Health Research
Nanyang Technological University (NTU) in Singapore has taken a significant stride in addressing one of the most pressing challenges of our time: the intersection of climate change and human health in tropical regions. In April 2025, the university officially launched the Centre for Climate Change and Environmental Health (CCEH), an interdisciplinary hub dedicated to understanding and mitigating the health risks posed by a warming planet, particularly in Southeast Asia and other tropical areas. This initiative comes at a critical juncture, as tropical climates—characterized by high humidity, frequent monsoons, and urban heat islands—amplify vulnerabilities to extreme weather, air pollution, and vector-borne diseases.
The launch, officiated by Senior Minister of State Dr. Amy Khor, underscores Singapore's commitment to proactive environmental health strategies. As a densely populated city-state, Singapore exemplifies the tropical urban challenges that CCEH aims to tackle, from transboundary haze to intensified heat stress.
The Urgent Need in Tropical Regions
Tropical areas like Southeast Asia face disproportionate climate-health threats. Global temperatures have risen, leading to more frequent heatwaves that, when combined with poor air quality, create synergistic health dangers. The World Health Organization (WHO) estimates that heat-related deaths reached approximately 489,000 annually over the past two decades, with 45% occurring in Asia. In Southeast Asia, air pollution alone could cost up to $600 billion by 2050, factoring in healthcare, lost productivity, and premature mortality.
Singapore's urban environment exacerbates these risks. The urban heat island effect raises temperatures by several degrees, while events like the Indonesian haze episodes worsen respiratory issues. CCEH's establishment responds directly to these realities, building on Singapore's Third National Climate Change Study to provide localized insights.
Leadership and Interdisciplinary Collaboration at CCEH
At the helm is Associate Professor Steve Hung-Lam Yim, a professor at NTU's Asian School of the Environment (ASE) and Lee Kong Chian School of Medicine (LKCMedicine). Prof Yim's expertise spans transboundary air pollution, climate-air quality interactions, and AI-driven forecasting, making him ideally suited to lead this effort. The centre draws from NTU's powerhouses: LKCMedicine for health modeling, ASE and Earth Observatory of Singapore (EOS) for environmental sciences, Singapore Centre for Environmental Life Sciences Engineering (SCELSE) for microbiomes, and Nanyang Environment & Water Research Institute (NEWRI) for water tech.
This synergy fosters holistic research, from molecular disease pathways to policy recommendations. Collaborations extend to NUS, Stanford, Imperial College London, and local agencies like the National Environment Agency (NEA).
Pillar 1: Tackling Air Quality and Pollution Challenges
Air pollution, intensified by climate change, forms CCEH's first pillar. Prof Yim's team has pioneered studies showing how stagnant weather patterns trap pollutants, leading to episodes linked to 135 million premature deaths globally from 1980-2020 due to fine particulate matter (PM2.5). In Southeast Asia, pollution supercharges storms, increasing rainfall by up to 50% and health burdens.
Recent work, including a 2026 presentation at the Better Air Quality Conference, highlights 'super pollutants'—ozone and particulates—that, under heat, heighten respiratory and cardiovascular risks. CCEH uses AI and remote sensing to forecast these, aiding urban planning in Singapore.

Pillar 2: Extreme Heat and Its Synergistic Effects
The second pillar targets extreme heat, a growing killer in humid tropics. CCEH's simulations reveal how greenhouse gas-driven warming and pollution interact to exacerbate mortality. A landmark study by Prof Yim's group was the first to quantify co-occurring heat-pollution events' health toll worldwide. In 2025, Southeast Asia saw record heat stress days, with climate change adding over 120 dangerous days in some areas.
Under Asst Prof Wang Jingyu's leadership, the team models urban heat islands and physiological limits, projecting vulnerabilities for Singapore's workforce. Findings inform heat action plans, like cooling centers and green infrastructure.Explore NTU's extreme heat research.
Pillar 3: Safeguarding Water Supply and Quality
Water challenges round out the pillars. Climate variability disrupts supply, breeding waterborne diseases amid flooding. CCEH integrates NEWRI's expertise to study contamination risks, linking them to health outbreaks in tropical monsoons. Singapore's NEWater success inspires scalable solutions for the region.
Projections warn of scarcity amplifying dengue and diarrhea, with CCEH advocating AI-monitored purification tech.
Groundbreaking Studies from LKCMedicine and Beyond
NTU's Lee Kong Chian School of Medicine drives simulations projecting climate impacts on mosquito-borne diseases like dengue. Economic modeling estimates productivity losses from absenteeism, vital for policy. A key 2026 study on 'heat and super pollutants' details synergistic effects in Southeast Asia, urging regional action.

Implications for Singapore and Southeast Asia
For Singapore, CCEH supports initiatives like Project Wolbachia, reducing dengue by 75% in treated areas, expanding to 50% coverage by 2026. Regionally, it addresses under-researched tropical risks, fostering ASEAN collaborations. Economic forecasts: unchecked pollution could drain billions, but CCEH's data-driven policies promise resilience.
| Climate Factor | Health Risk | SEA Projection |
|---|---|---|
| Heat + Pollution | Respiratory/Cardio | Escalating by 2050 |
| Air Quality | Premature Deaths | $600B cost |
| Water Scarcity | Waterborne Diseases | Increased outbreaks |
Future Outlook: Innovations and Careers
CCEH eyes AI for predictions, microbiome interventions, and sustainable infrastructure. Philanthropy, like Tsao Family support, fuels expansion. For aspiring researchers, opportunities abound in env health at NTU—postdocs, faculty roles blending climate science and medicine.
Events like the 2026 Regional Action Forum on air pollution-heat synergies signal growing momentum.
Stakeholder Perspectives and Actionable Insights
Prof Yim emphasizes: “Southeast Asia is under-represented; CCEH fills this gap.” Policymakers gain tools for heat alerts; communities, adaptation strategies like green roofs. Students: pursue env health degrees at NTU for impactful careers.
