The latest State of the Climate report from the Bureau of Meteorology and CSIRO has painted a concerning picture of Australia’s climate, with significant changes noted in temperature, ocean conditions, and extreme weather patterns.
Dr. Karl Braganza, climate services manager at the Bureau of Meteorology, described the situation as “a wicked problem” that is impacting the country’s society and economy.
The report highlights that Australia’s average temperature has risen by 1.51°C since 1910, with nine of the warmest years recorded since 2013.
Projections indicate that this warming trend is likely to continue, largely driven by accumulated greenhouse gases.
The frequency of extreme heat days has also increased significantly, with heatwaves lasting longer and intensifying, marking a stark contrast to conditions experienced in previous decades.
Ocean temperatures are not exempt from this alarming trend.
Rising ocean temperatures and frequent heatwaves pose serious risks to ecosystems and public safety.The report reveals that the world’s oceans have absorbed approximately 90% of excess heat, leading to dangerous marine heatwaves that threaten ecosystems like the Great Barrier Reef.
Furthermore, rising ocean temperatures have contributed to heavier rainfall, as warmer air retains more moisture.
The report warns of a worsening bushfire risk, with many regions experiencing an increase in the number of dangerous fire weather days.
Experts predict that bushfires will become more severe due to climate change, potentially leading to higher costs for insurance and increased fatalities as people choose to remain in their homes during emergencies.
Carbon dioxide emissions continue to climb, exacerbating the climate crisis. Data from the Kennaook-Cape Grim monitoring station shows a significant rise in greenhouse gases over the past four decades, underscoring the urgency for action to mitigate further warming.
As Australia faces these critical climate challenges, the report stresses the importance of reducing emissions to keep global temperatures in check and avert catastrophic impacts.
