澳大利亚正面临日益频繁的气候灾害，包括洪水、极端高温和热浪，普通民众在反复灾难中承受越来越大的经济压力。[1]全球变暖已达1.55度，超过《巴黎协议》设定的1.5度目标。[1]澳大利亚联邦政府的灾难恢复支出大幅攀升，从2000年代初的每年1.54亿澳元增至2024年预算的114亿至160亿澳元。[1]
保险成本急剧上升给民众造成沉重负担。[1]根据保险咨询公司Finity的研究，自2021年以来，新南威尔士州的平均保险费上升63%至4680澳元，昆州上升43%至4335澳元，维州上升66%至2646澳元。[1]更为严峻的是，澳大利亚有242,000户住宅面临最高洪水风险，其中186,000户未投保洪水险。[1]气候评估报告指出，到本世纪中期，150万人将生活在高海平面上升和沿岸洪水区域。[1]
专家认为政府在气候适应方面的投入远远不够。[1]保险委员会主席Andrew Hall呼吁建立300亿澳元的洪水防御基金用于10年投资。[1]独立议员Zali Steggall建议将GDP的四分之一个百分点用于适应资金。[1]研究表明防灾投资回报率显著：防灾每投入1美元可节省灾后重建成本10美元，昆州重建管理局投入2.44亿澳元的项目产生了9.88亿澳元的避免成本，实现四比一的回报率。[1]英国第四次气候变化评估称气候适应需年投110亿英镑，折合210亿澳元。[1]环保中心主任Kirsty Howey表示"一切都在崩溃"。[1]
Australia is confronting an escalating climate crisis that ordinary citizens increasingly cannot afford to endure. Global warming reached 1.55 degrees in 2024, exceeding the Paris Agreement's 1.5-degree target [1], and the nation is experiencing intensifying floods, extreme heat, and heatwaves. The financial toll on households has become severe, with insurance premiums rising dramatically across states: New South Wales saw a 63 percent increase to 4,680 Australian dollars since 2021, Queensland a 43 percent rise to 4,335 dollars, and Victoria a 66 percent increase to 2,646 dollars [1]. Meanwhile, 242,000 Australian homes face the highest flood risk, yet 186,000 of these remain uninsured against flooding [1].
Government disaster recovery spending has surged from 154 million dollars annually in the early 2000s to between 11.4 and 16 billion dollars in the 2024 budget [1], yet experts warn this reactive spending is insufficient without substantial preventive investment. The Insurance Council chair Andrew Hall has called for a 30 billion dollar flood defense fund for a decade of strategic investment [1], while independent member of parliament Zali Steggall advocates dedicating a quarter of a percentage point of GDP to adaptation funding [1]. Research demonstrates the cost-effectiveness of prevention: every dollar invested in disaster mitigation saves approximately 10 dollars in reconstruction costs [1]. Queensland's reconstruction management authority invested 244 million dollars in projects that generated 988 million dollars in avoided costs—a four-to-one return [1]. By mid-century, 1.5 million people are projected to live in high-risk coastal flood and sea-level rise zones [1], underscoring the urgency of comprehensive national adaptation strategy and adequate climate resilience funding.
