Global climate change although often thought of as a recent issue is not restricted to recent geologic time. Evidence also exists for past climate change events. Discussion 5 focuses on the study ofpaleoclimatology(past climates) and how that can help us understand recent concerns about global climate change.
In order for your instructor to have a better understanding of your prior knowledge and learning experiences with global climate change you are asked to complete apre-and post-lesson survey. Your surveys contribute to your participation grade for discussion 5 but are NOT graded as correct or incorrect responses. Please answer as honestly as possible. Also provide a paragraph on how you evaluate the authority and reliability of the article that you submit for the assignment. See the guide below for more information.
Quality Assessment Guide – Evaluating the quality of what you find
Never just accept that the information you found is authoritative and reliable. Especially if it is found on the web. Before you use information you need to evaluate it to see if it is reliable information supplied by authoritative authors.
Not all books are reliable or authoritative.
Magazines and journals and newspapers contain content of varying authority.
In the scholarly world a journal can say we will not publish your article because your peers dont think it is any good These are Peer Reviewed Journals. Every article is evaluated by other people working in the same field before being included in the publication.
Be particularly careful with web pages and documents. The web is not controlled by any entity. Anyone can put misinformation on the web and no one can force them to take it down. This is definitely a buyer-beware world.
