Write a short paper describing a paleoclimate proxy of your choice, and summarize an example of it being used in a scientific study. Specifically, your paper should: (1) describe in detail how the proxy “works” – what is it, what climate variables impact it and how; (2) explain the data provided by the proxy and how it is analyzed and interpreted; (3) discuss the strengths, weaknesses, and assumptions involved with using the proxy as a source of climate information; and (4) summarize briefly how the proxy has been used in an actual scientific study. You must refer to at least one study published in valid peer‐reviewed literature (refer to a minimum of 2 peer‐reviewed sources). The following specific content is required: Your paper should comprise no more than three double‐spaced pages, addressing all (4) components listed above, including properly cited references. Copy and paste figures and/or tables onto a maximum of two additional pages at end of your paper (do not embed them in the text!) to illustrate the proxy and data used in your case study. Label and cite the figures (tables) sequentially in your text. Be sure to write your own captions for each figure (table) to explain what they show, and properly cite the source where they come from. These figures can come from any source, cited properly. Properly cite all information in your text, and then provide a properly formatted bibliography of all references used in a final section labeled “References cited” at the end of the paper. You must include at least two peer‐reviewed scientific references. But it is expected you will also cite other non‐peer reviewed sources. Use a consistent bibliographic style.
