Climate research at the Earth Observatory of Singapore fills a gap of much-needed information on climatic forces in Southeast Asia, allowing better forecasts of regional consequences that can be expected from global climate change. Research conducted by the climate group focuses on regional climate monitoring, and the measurement and modelling of past and modern tropical climates.

Research Areas

Sea Level History

Geodetic data from the 19th through 21st centuries, such as the Gravity Recovery and Climate Experiment (GRACE), tide gauges, satellite altimetry and GPS measurements of surface mass loading all provide critical information on processes such as glacier melting and sea-level change. Climate geodesy with its measurements, and their analysis and modeling, are critical to understanding the effects of present-day climate change. 

Longer term validation of climate and tectonic models must rely on the rock record, the subject of Adam Switzer’s research team. Coastal Change Research studies the both the long-term sea level variations from climatic change and the short-term dramatic change from storms or tsunamis.

Atmosphere and Ocean Interactions

Global Climate Change is driven by the interactions between the atmosphere and the oceans. Models of ocean and atmospheric circulation today and knowing how these interactions have influenced past climate are important to solving global questions as well as regional weather and pollution.

Environmental Change

The present may be the key to the past, but the past is also the key to the future. Paleoclimate gives geoscientists a sense of what has occurred on earth so we know what we might expect in the future.

Study of isotopic systems, corals, speleothems, coastal deposits, and more all contribute to our understanding of Earth’s climate.
