· The Earth’s Climate System · Climate Function · “Climate is what you expect, and weather is what you get.” (World Ocean Review) · Weather is short term, climate is long term (next year, 10 years away) · Earth’s climate is a result of interactions of many components within the system.
· Sun and ocean interactions, ocean and atmosphere.
· Troposphere- · Lowest level of the atmosphere, we live in the troposphere. Primarily composed of nitrogen and oxygen as well as water vapor.
· Majority of weather experienced happens in the troposphere.
· Stratosphere · Second layer of the atmosphere · Planes fly in the stratosphere · Hydrosphere · Comprised of all liquid surface and subterranean water · Fresh and Salt water.
1 · Biosphere · Is the sum of

3 · Energy Cycle · Solar radiation is transformed into internal heat, potential energy, latent energy, and kinetic energy and moves around in various ways by the atmosphere, oceans, land and ice. Some is also radiated back into space (Trenberth) · There must be a balance between the incoming and outgoing radiations.
· Energy cycle drives weather systems, ocean currents, and determines climate (Trenberth).
· Once energy is absorbed and cycled through the atmosphere the energy is then radiated back into space.
· Causes of recent changes · Burning of fossil fuels · Increases CO2 within the atmosphere trapping in more heat.
· CO2 absorbs the heat that is bounced off the earths surface.
· When the sun’s energy reaches the earth, some of that energy is absorbed and some is radiated back, energy balance. Greenhouse Gases absorb the energy that is radiated back into space, intern warming the atmosphere.
4 · “Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone.”(Time for Change) · Greenhouse gases act like a mirror and reflect to earth some of the heat energy that would normally be lost into space. (Time for Change).
· Increase in energy consumption world wide, CO2 and other pollutants at new highs.
5 · Climatic Impact From Atmospheric Energy and Geological Events.
· Energy Transported · Energy is transferred
