Buried in sediment under an ancient crater lake in Central Otago, fossilised leaves have helped Kiwi researchers find the long-term effects of increasing CO2 levels on melting Antarctic ice. Preserved in sediment containing no oxygen to aid decomposition, the sediment cores were essentially stacked annual layers similar to tree ring or ice cores. Studying the […]
