巴布亚新几内亚的CO2渗漏显示,酸化逐渐摧毁珊瑚礁,减少多样性和恢复。 CO2 seeps in Papua New Guinea show acidification gradually destroys coral reefs, reducing diversity and recovery.

在巴布亚新几内亚,自然的二氧化碳渗漏创造了一个现实世界的实验室,科学家在这里研究海洋酸化对珊瑚礁的影响。 In Papua New Guinea, natural CO2 seeps create a real-world lab where scientists study ocean acidification’s effects on coral reefs. Katharina Fabricius博士在《通讯生物学》上发表的研究报告显示,不断上升的二氧化碳将珊瑚礁生态系统从不同的珊瑚社区逐步转向以藻类为主的简化系统,生物多样性和结构复杂性较低。 Research by Dr. Katharina Fabricius, published in Communications Biology, shows rising CO2 gradually shifts reef ecosystems from diverse coral communities to algae-dominated, simplified systems with less biodiversity and structural complexity. 虽然没有突然崩溃发生,但珊瑚覆盖和婴儿珊瑚数量减少,威胁着珊瑚礁的恢复。 While no sudden collapse occurs, coral cover and baby coral numbers decline, threatening reef recovery. 自工业时代以来,海洋的酸度增加了30%,预测显示,到2100年,pH值进一步下降到7.8。 The ocean has become 30% more acidic since the industrial era, and projections show further pH drops to 7.8 by 2100. 与变暖不同,酸化是全球性和不可逆转的,不减少排放,加剧对海洋生物和沿海社区的威胁。 Unlike warming, acidification is global and irreversible without cutting emissions, compounding threats to marine life and coastal communities. 研究强调,由人类二氧化碳排放驱动的海洋酸化只有在排放停止时才停止。 The study underscores that ocean acidification, driven by human CO2 emissions, will only stop when emissions cease.
