AS the UK struggles with the worst snow for six years across large parts of England, down under the Australians are having to deal with the worst heatwave in decades, with temperatures in excess of 43C (109F) in the south-eastern part of the country. Health officials in South Australia are blaming the high temperatures for an increase in the number of sudden deaths among the elderly. While in the north near Queensland authorities are monitoring a low pressure system that could develop into the state’s second cyclone within a week. More than 60 per cent of Queensland is covered by floodwaters and more devastation is expected. Already there are almost 3,000 properties in the north of Townsville surrounded by floodwaters caused by ex-tropical cyclone Ellie.
The snowfall in England resulted in schools being closed, public transport closures and airport delays. The heatwave in Victoria is the worst since 1908. Wildfires in the west of the state made worse by dry conditions and sweeping winds destroyed 2,000 hectares (4,900 acres) of forest and grassland, forcing residents to flee their homes, emergency workers. The high temperatures resulted in a massive increase the use of air conditioners which have claimed to have caused a breakdown in Melbourne’s electricity grid – leaving half a million homes without power. The economic cost of the heatwave in Melbourne is estimated to be 100,000 Australian dollars.
In the UK the big snow is estimated to have cost the country £1bn in lost productivity due to approximately 20 per cent of the country’s workforce is believed to have taken Monday off due to the extreme weather. Many businesses in London and the south-east were forced to operate on a limited basis with transport services in chaos after up to eight inches of snow. Nearly half of businesses in London were operating at only 50 per cent capacity.
These recent extreme weather events clearly demonstrate our vulnerability to the impacts of a sudden change in climate. The social, economic and environmental impact of such extreme weather should be a warning to us all about what we can expect in the future as the planet warms up and the climate changes. We need to act now to prevent the possibility of run away climate change. We need to make the necessary investment to ensure the infrastructure, social and emergency services can adequately cope with extremes change in the weather.
