Entrapping hidden changes in nature

The study of climate change is a very important field of science, since life is directly affected by these changes. Many proxies, i.e. data previously preserved within speleothems, sediments, tree rings, corals, etc., have been observed and many theoretical models have been developed in order to gain a comprehensive understanding of past and future climate. Investigating the past climate changes leads to the forecasts of future possibilities. Therefore, enlightening the past is a keystone to answer questions about climate as well as vegetation, life, evolution, and nature. Paleoclimatology, the understanding of changes in climate during the history of Earth, has become a popular area of research at the intersection of climatology, chemistry, physics and mathematics. In order to extract the proxy information, many observations and mathematical studies have been performed.
