MET 112 Global Climate Change - Lecture 1 “Introduction and Course Outline” Dr. Eugene Cordero San Jose State University 1 MET 112 Global Climate Change Lecture Outline Introductions and welcome Discussion of greensheet Learning Contract Academic dishonesty Global climate change: – What’s it all about?? 2 MET 112 Global Climate Change Academic Integrity Integrity of university, its courses and degrees relies on academic standards. Cheating: – Copying from another’s test, cheatsheet etc. – Sitting an exam by, or as, a surrogate. – Submitting work for another Plagiarism: – Representing the work of another as one’s own (without giving appropriate credit) 4 MET 112 Global Climate Change Plagiarism Judicial Affairs http://sa.sjsu.edu/judicial_affairs/index.html Look at the Student Code of Conduct Read through SJSU library site on Plagiarism http://www.sjlibrary.org/services/literacy/info_comp/plagiarism.htm http://turnitin.com/ 5 MET 112 Global Climate Change Ok, let’s start talking about climate change! Definitions Weather: – the state of the atmosphere at a particular point in time. Climate: – the accumulation of daily or seasonal weather events over a longer time period. Meteorology and Climatology represent the study of weather and climate respectively, but are each components of Atmospheric Science and are dealt with in this course MET 112 Global Climate Change 8 Definitions Hypothesis: – is a proposed explanation for a phenomenon or some observation. Theory: – is a logically self-consistent explanation describing the behavior of natural phenomenon (originating from some observations) In a colloquial sense, the word theory is used to mean an idea that may or may not be true; a scientist would refer to this as a hypothesis. When a scientist uses the word theory, s/he means a hypothesis which has been tested and has so far passed all of its tests.

Activity 1b You are watching your favorite news program (i.e. CNN, BBC or NBC) and they are reporting on a massive heat wave that is crippling the Midwest. The news reporter states that this event is clearly a result of climate change. Your roommate laughs and remarks that the news reporter is ‘full of it’. Who is right and why?
