The world is heating up faster than we thought, and the consequences could be catastrophic. A leading climate agency has reported that 2025 was the third-hottest year on record, marking the warmest decade ever. This alarming trend suggests we might hit a critical temperature threshold much sooner than anticipated.
Last year was only 0.13 degrees Celsius cooler than the record-breaking year of 2024 and a mere 0.01 degrees cooler than 2023. But here's where it gets controversial: the past three years have averaged more than 1.5 degrees Celsius above pre-industrial levels, a threshold set in the Paris Agreement. This increase is primarily due to the build-up of greenhouse gases and exceptionally high sea surface temperatures, partly influenced by an El Niño event.
This 1.5-degree target is crucial because exceeding it is believed to have severe consequences, as warned by the Intergovernmental Panel on Climate Change. They predict significant impacts on human health, the loss of ecosystems, and more frequent extreme weather events.
And this is the part most people miss: the latest data indicates that we could breach the 1.5-degree mark before the end of this decade, over a decade earlier than the initial projections made when the Paris Agreement was signed in 2015.
"We are approaching it very rapidly," says Carlo Buontempo, Director of the Copernicus Climate Change Service.
Australia is also taking steps. Recent reports show that annual emissions are now 29% below 2005 levels. The federal government has revised its 2030 target to reduce emissions to 43% below 2005 levels by 2030, aiming to contribute to the global effort to keep warming within the 1.5-degree target.
However, the Climate Council urges more urgent action, highlighting the devastating impacts Australians are already experiencing, such as bushfires, heatwaves, floods, and cyclones. According to the Climate Council, "All signs point to the need to act right now, not tomorrow." They emphasize that every action to cut climate pollution helps secure a safer future.
Furthermore, the economic costs are mounting. Last year, floods and cyclone damage cost the country over $2 billion in insured losses, and flood zone homes were valued at $42 billion less due to increased risk. Even those who avoided direct damage will face higher insurance premiums, lost farm production, higher food prices, and increased health costs. Economists argue that allowing climate change to worsen will be more expensive than investing in renewable energy and cleaner transport.
