IT'S HOT IN PARRAMATTA Cities are hotter than rural areas due to the Urban Heat Island Effect 2015 SYDNEY morning summer surface temperatures in treeless urban areas warmest year on record globally Greater heat absorption leads to rising surface temperatures during the day 12.8°C higher than vegetated non-urban area More heat is absorbed by buildings, roads and other hard surfaces At night, hard surfaces re-radiate the heat into the surrounding environment 33 32 31 30 I URBAN HEAT ISLAND Suburban Residential Rural Farmland Rural Commercial Urban Residential Park City Suburban Residential PARRAMATTA has more hot days than Sydney 15 PARRAMATTA SYDNEY 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 PEOPLE IMPACTS CITY IMPACTS Damages electricity and transport infrastructure EXTREME HEAT Dehydration Periods of Heat cramps extreme heat Heat exhaustion Increases need for air can cause heat related illnesses conditioning which increases cost of living Heat stroke Worsening of existing medical conditions Increases peak energy demand, driving up infrastructure costs Increases the risk of HEATWAVES power cuts HAVE BEEN SHOWN Increases air pollution (more ozone created from motor vehicle exhaust emissions) TO DRAMATICALLY INCREASE PATIENT PRESENTATIONS AT HOSPITALS COST OF EXCESS HEAT IN TERMS OF WORK ABSENTEEISM TO AUSTRALIAN ECONOMY IN 13/14 FY = can have a considerable effect on human health as the body cannot recover from daytime extremes INCREASED NIGHT TIME TEMPERATURES $6.7 BILLION WHO ARE MOST AT RISK?
