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)

DefinitionsDefinitions

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

DefinitionsDefinitions 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.

It is has water, oxygen and a hospitable climate

Reference: IPCC

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

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?
