... sedimentary rocks. When bacteria and algae in the ocean grow by taking in carbon dioxide, they prefer the ordinary carbon-12 atoms. As a result, the sea becomes enriched in carbon-13, which is acceptable to sea creatures building their carbonate shells. Variations in carbon-13 therefore record how much ph...Climate changes are linked between Greenland and the Antarctic
