The year 2024 was the world’s warmest on record globally, and the first calendar year in which global temperatures exceeded 1.5°C above its pre-industrial levels. The official declaration was made on Friday by the Copernicus Climate Change Service, the European Union’s Earth observation program. It comes as wildfires continue to tear through Los Angeles, California – a disaster scientists say was made worse by climate change.

Description In a rapidly changing climate, history may no longer be our best guide for what’s next. Our weather is noticeably more chaotic, unpredictable and dangerous. Climate drivers – recurring phenomena such as El Niño/La Niña, the Southern Annular Mode, and the Indian Ocean Dipole – may be interacting in complex new ways. Rising ocean temperatures are affecting rainfall patterns. Extreme events are becoming worse, more common, and less predictable.

In late October 2023, after three years of above average rainfall had given way to El Niño and Australia’s driest three months on record, fires in the Western Downs Region of southeast Queensland destroyed more homes than were lost in that state in the infamous 2019-20 Black Summer fires.

From Kakadu and the Great Barrier Reef in the North, to the Snowy Mountains in the Southeast, and jarrah and marri forests in the Southwest, Australia is home to incredibly diverse ecosystems. Many of our plants, animals, birds and fish are found nowhere else in the world. Our First Nations people protected these living wonders through their holistic approach to managing the land and caring for Country for more than 65,000 years.

Description For the past three years, Australia has experienced wetter than average conditions, with record-breaking rainfall and floods across New South Wales (NSW), Queensland, Victoria, South Australia and Tasmania (BoM 2022). This has been due to a rare, ‘protracted' La Nina event, together with a negative phase of the Indian Ocean Dipole and a positive phase of the Southern Annular Mode.

Australia has long been referred to as a land of “drought and flooding rains”, prone to bushfires as well as intense rainfall events. Periods of hot, dry, windy weather have regularly dried out vegetation and made it susceptible to ignition, alternating with prolonged wet periods that have promoted rapid and widespread vegetation growth. Climate change, driven by the burning of coal, oil, and gas, is worsening these extreme weather events (IPCC 2021a).
