Cranking up the intensity: climate change and extreme weather events
KEY FINDINGS 1. Climate change is influencing all extreme weather events in Australia. All extreme weather events are now occurring in an atmosphere that is warmer and wetter than it was in the 1950s. Heatwaves are becoming hotter, lasting longer and occurring more often. Marine heatwaves that cause...

Climate change is influencing all extreme weather events in Australia. All extreme weather events are now occurring in an atmosphere that is warmer and wetter than it was in the 1950s. Heatwaves are becoming hotter, lasting longer and occurring more often. Marine heatwaves that cause severe coral bleaching and mortality are becoming more intense and occurring more often. Extreme fire weather and the length of the fire season is increasing, leading to an increase in bushfire risk. Sea level has already risen and continues to rise, driving more devastating coastal flooding during storm surges. 2. Some of the most severe climate impacts the world has experienced have occurred in 2016. Arctic sea ice reached its lowest annual extent on record while record sea surface temperatures drove the worst coral bleaching event in the Great Barrier Reef’s history. Tropical Cyclone Winston was the most intense cyclone to hit Fiji on record, while Hurricane Otto was the southernmost hurricane to hit Central America on record. Canada experienced its costliest wildfire in history in Fort McMurray, forcing the evacuation of almost 90,000 people. The US state of Louisiana experienced 1-in-500 year rains that brought severe flooding leading to 30,000 rescues and 13 deaths. 3. Across Australia, extreme weather events are projected to worsen as the climate warms further. Extreme heat is projected to increase across the entire continent, with significant increases in the length, intensity and frequency of heatwaves in many regions. The time spent in drought is projected to increase across Australia, especially in southern Australia. Extreme drought is expected to increase in both frequency and duration. Southern and eastern Australia are projected to experience harsher fire weather. The intensity of extreme rainfall events is projected to increase across most of Australia. The increase in coastal flooding from high sea level events will become more frequent and more severe as sea levels continue to rise. 4. The impacts ...
