Chapter 13 Climate change and disaster risks: The Singapore response

Abstract

The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) (Intergovernmental Panel on Climate Change, 2007) of 2007 concluded that most of the warming of the climate is very likely driven by human activities that increase greenhouse gas (GHG) concentrations in the atmosphere. Activities such as burning of fossil fuels for power generation and in vehicles, as well as increasing deforestation, result in emissions of four long-lived GHGs: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and halocarbons (a group of gases containing fluorine, chlorine, or bromine). The report projects that by the end of the 21st century global temperatures could rise by 1.1–6.4°C over 1990 levels, while global mean sea levels could rise by 18–59cm, depending on future scenarios of varying global emission levels. This is likely to adversely impact ecosystem resilience, putting many plant and animal species at the risk of extinction. Sea level rise and coastal erosion coupled with temperature extremes, heat waves, and heavy precipitation events that are projected to become more frequent will affect the health and well-being of millions of people around the world.
