ASSIGNMENT #2:IMPLICATONS OF HISTORICAL CLIMATE CHANGE
Introduction
The purpose of this assignment is to gain a greater understanding of past climate change events. As discussed in the course instructional content, a number of historical climate change events have occurred in the Earth’s past. You will be asked to select one of these events and describe it in the context of the radiation balance, to discuss the impact of the event, and also to include factors that have contributed to or caused this event.
Assignment (total 20 marks)
As mentioned in the instructional content, the Earth has undergone a number of long and abrupt climate change events, suggesting that the Earth’s climate, and more specifically temperature, has not been consistent over the past 4 billion years. You are asked to research a historical (i.e., Snowball Earth or Eocene Thermal Maximum) or abrupt climate change event (i.e., Younger-Dryas event) and write a short research paper that will address the following in the body of the paper:
a description of the event (i.e., how climate has changed, date of occurrence, length of event, etc.) (5 marks);
a discussion on the impacts of the event on the greenhouse effect and on the physical and biological environments
(5 marks); andan explanation of the factor(s) that contributed or caused the event (i.e., Milankovitch cycles, sunspot activity, etc.) (5 marks).
The paper should also include an introduction and conclusion. The introduction should introduce the topic to the reader, as well as having a clear thesis statement (i.e., what the paper will discuss). The conclusion should recap the main points of the paper for the reader. An additional 2 marks will be given for these sections (1 mark for each section).The research paper should be no more than 1300 words (not including figures/graphs or references). Any information beyond the 1300 word limit will not be read and graded.
Include any figures or graphs that you think are relevant to the discussion of the historical climate event. Make sure to provide an appropriate caption and reference for the figures/graphs, and that the figures/graphs are cited properly in the text (i.e., “The temperature during the event increased (Fig.1)”.
All information used in the research paper that comes from another source must be referenced properly using an acceptable format (for more information on referencing see: http://libguides.lib.umanitoba.ca/citingandwriting). This site will also provide information on writing a research paper if you are not familiar with this format. You must only use credible sources for your paper (Wikipedia or any encyclopedias, as well as personal websites are not credible sources).
An additional 3 marks will be given for the style of the paper. This includes spelling, grammar, sentence and paragraph structure, as well as overall presentation
