Sydney temperatures to soar: CSIRO report
Average Sydney temperatures will soar by 4.8 degrees by 2070, according to a CSIRO report commissioned by the NSW State Government.
In summer, maximum temperatures could rise by up to seven degrees by 2070, according to newspaper reports.
The CSIRO has predicted Sydney would resemble the dry, harsh conditions in the village of Paterson, 150 kilometres north-west of Sydney, in less than 25 years.
Heat-related deaths will increase from the current average of 176 per year to 1312 by 2050, the report predicts.
The frequency of droughts is also tipped to increase to nine out of every 10 years by 1970, forcing Sydney residents to reduce water consumption by 54 per cent for the city to remain sustainable within the next 20 years.
The CSIRO report says the coastline will be devastated by 110-metre storm surges by 2100 and bushfires will almost double as rainfall is expected to fall by 40 per cent.
Meanwhile, a report due to be released today says a 30 per cent cut in greenhouse gas emissions would cost $75 billion in new infrastructure.
Thirty per cent is the amount necessary to meet scientists’ calls for reductions to combat climate change, the newspaper reports said.
On Friday, the world’s leading body of climate scientists, the Intergovernmental Panel on Climate Change, will release a report forecasting global temperature rises of between two per cent and 4.5 per cent
