Sydney, Australia’s largest city, is experiencing ‘life-threatening’ floods after torrential rainfall – equivalent to about a month’s worth of rain – battered parts of the city and its surrounding areas over the weekend, causing dams to overflow and waterways to break their banks. As of Tuesday, evacuation orders had been issued for a whopping 50,000 people in and around Sydney, while the New South Wales government has also declared an emergency in 23 areas. This weekend’s floods marks the fourth flood emergency in 16 months for Sydney, a city home to five million people, and is a stark reminder of the worsening impacts of climate change in Australia.
