Climate change impacts, and the adaptation needs, will vary by region and sector. Some of the impacts will be gradual, as a long-term increase in global temperature brings about a rise in sea level, g... reater water scarcity in some regions and changes in precipitation patterns. Energy demand patterns will change (such as for heating and cooling), power plant cooling and efficiency will be affected, as will hydropower output, and coastal infrastructure (including refineries, liquefied natural gas "LNG" plants and power plants) will be threatened (Figure 3.1). For example, in the United States alone nearly 300 energy facilities are located within 1.2 metres of high tide (Strauss and Ziemlinski, 2012). Other impacts of climate change are likely to be more sudden and destructive, with extreme weather events, such as tropical cyclones, heat waves and floods, expected to increase in intensity and frequency (Box 3.2). Cyclones can damage electricity grids and threaten or severely disrupt offshore oil and gas platforms, wind farms and coastal refineries. Heat waves and cold spells will impact upon peak load energy demand, putting greater stress on grid infrastructure and undermining the ability of power plants to operate at optimum efficiency. Gradual and sudden climate impacts can also interact, such as a sea level rise and more powerful storms combining to increase storm surges. Furthermore, disruptions to the energy system caused by climate events can have significant knock-on effects on other critical services, such as communications, transport and health.
