2 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??

3 MET 112 Global Climate Change Learning Contract  Instructor –On time and prepared. –Answers questions. –Approachable and friendly. –Fair with assignments and grades. –Genuinely concerned about your learning and intellectual development.  Students –Make every effort to arrive on time; and if late, enter class quietly. –Preserve a good classroom learning environment by a) refraining from talking when other people are talking b) turning off cell phones. –Be courteous to other students and the instructor. –Aware that learning is primarily their responsibility. –Aware of universities policy on academic integrity and pledge to abide by them at all times. –Have read and understand what plagiarism is and know how to cite sources properly.

4 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)

5 MET 112 Global Climate Change Plagiarism  Judicial Affairs  Look at the Student Code of Conduct  Read through SJSU library site on Plagiarism 

Ok, let’s start talking about climate change!

7 MET 112 Global Climate Change Definitions  Weather: –  Climate: –  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

8 MET 112 Global 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

9 MET 112 Global Climate Change Definitions  Hypothesis: –  Theory: –  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.

10 MET 112 Global Climate Change 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.

World Population 6,446,131,400 The Challenge: Sustainable Management of an Ever-Changing Planet

The Challenge: Sustainable Energy

The Challenge: Food Security

Food production needs to double to meet the needs of an additional 3 billion people in the next 30 years Climate change is projected to decrease agricultural productivity in the tropics and sub-tropics for almost any amount of warming

The Challenge: Sustainable Forestry

Wood fuel is the only source of fuel for one third of the world’s population Wood demand will double in next 50 years Climate change is projected to increase forest productivity, but forest management will become more difficult, due to an increase in pests and fires

The Challenge: Water Security

Water Services One third of the world’s population is now subject to water scarcity Population facing water scarcity is projected to double over the next 30 years. Climate change is projected to decrease water availability in many arid- and semi-arid regions

21 MET 112 Global Climate Change 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?  Form group of two – names on the top of the paper Activity 1b
