罗伯邓巴尔：在海洋和冰层中追寻远古气候

罗伯邓巴尔不断收集一万二千年前的气候数据，在远古海床、珊瑚石和冰层内寻找线索。他的工作对于我们为调整现在的气候而设定基准线——也对追踪日益严重的海洋酸化十分重要。

Earth’s climate history is locked in ancient corals, sediments, and ice, revealing how oceans have shifted over millions of years. Recent drilling in Antarctica shows that giant ice sheets have melted and reformed dozens of times, with just small temperature increases triggering dramatic sea level rise. Today, ocean acidification is accelerating as a third of human-generated CO2 dissolves into the sea, threatening marine life that has never faced such rapid chemical change. Understanding these intertwined forces is key to setting meaningful climate targets and protecting global biodiversity.
