When we want to look into the past, the greatest tools we have are called proxy climate records. These are natural archives that record variations in climate, including ice cores, lake sediments, corals, cave stalagmites, peat and tree trunks. These archives provide us with climate change data reaching further back than the few hundred years of information we can get from human instrumental weather records. |
