Feel the heat in western NSW
15 Nov 2004
Climate change would lead to more hot spells and fewer cold snaps, with the number of 35 degree-plus temperature days in New South Wales expected to exceed 100 days every year. A study by CSIRO said with many more hot days, heat stress to animals and crops was likely to increase, while the quality of transport infrastructure would decline, with greater frequency of buckling of railway lines and melting of road tar. Earlier CSIRO research predicted that average temperatures in parts of NSW would rise by 6.4 degrees by 2070, while rainfall could drop by as much as 40 per cent. The warmer temperatures could harm crops such as stone fruits and some grapes. Towns in the far west of the states, such as Wilcannia, Walgett and Cobar, would be worst hit. Wilcannia already has 59 days a year above 35 degrees. By 2030 its residents can expect up to 83 days above 35 degrees. Canberra and Bathurst may become more temperate. Canberra is now below zero on 62 days a year, but this could drop to 39 by 2030 and just nine days by 2070.
