There is significant evidence from studies based on climate archives that the Earth’s climate about 10 000 years ago was very different from the present climate; it has changed a lot since the last glacial period which ended about 10 000- 12 000 years ago (Chappell, 1998). Hence, about 10 000 years ago the Earth was buried under ice sheets and it was much cooler than present temperatures (see Figure 1, Appendix) (Chappell, 1998). The Earth that has been cycling between cold and warm climates for ages and is currently in the interglacial period where it has slowly become warmer along with a rise in sea level (Watts, 2009). There are many climate archives which can help scientists study past climates and their development over time. Climate archives contain information about past climate conditions and are also referred to as climate proxies (Ruddiman, 2014). Scientists use climate proxies to study climate changes, however they do not directly extract information from them, instead they look for the mechanism by which climate signals are recorded or stored within the proxies; often called climate parameters (Ruddiman, 2014). Therefore, this paper will discuss how through the use of corals and foraminifera scientists can better understand the climate from the past along with the help of certain climate proxies and parameters.
