Australia needs national plan for rising seas

Australia must examine the legal liability and insurance cover associated with property loss and damage due to climate change, improved early warning systems for extreme seas, and work to prevent the spread of tropical diseases such as dengue fever. “The key message that emerged from the inquiry is the need for national leadership in managing Australia’s coastal zone in the context of climate change,” Jennie George, a government MP and committee chair, said in launching the report on Tuesday. “This is an issue of national significance.” The report said thousands of kilometers of coast around Australia was at risk from rising sea levels and extreme weather events caused by climate change. An estimated 711,000 homes were within 3 km (2 miles) of the coast and less than 6 meters (yards) above sea level. …
