Climate System
What makes up the Earth’s climate system?
ACTIVITY
Draw a picture, with labels, of what components make up a climate system.
Natural Climate System
Components of a Climate System
Human Influenced Climate System
In Summary:A region's climate is generated
by the climate system: Atmosphere, Ice, Vegetation,
Land, and Oceans
Video
Key Terms:
• Weather is the present condition of temperature, humidity, wind, precipitation, and other meteorological elements and their variations over short time periods—hours and days.
• Climate is the long term—30 plus year—average of temperature, humidity, wind, precipitation, and other meteorological elements.
• Climate System is the Earth’s components that influence climate.
Greenhouse Gasesand the
Greenhouse Effect
What do you think are the greenhouse gases?How would you define the greenhouse effect?
Earth’s Atmospheric Gases
Misc. Gases, 0.01%
Carbon Dioxide, 0.03% Water Vapor, 1.96%
Argon, 0.91%
Oxygen, 20.54%
Nitrogen, 76.55%
Misc. Gases
Carbon Dioxide
Water Vapor
Argon
Oxygen
Nitrogen
Greenhouse gases absorb and emit infrared radiation (long wave). They do not absorb short wave radiation (most of incoming solar radiation).

The Earth’s Energy Budget and the Climate System
• How would changing the Earth’s surface impact the absorption, reflection, and radiation of the sun’s energy?
ACTIVITY
AlbedoTo calculate albedo, divide the reflective light by the incidence (incoming) light: Albedo = Reflective light
Incidence light
to convert to a percentage multiply by 100
For example: The florescent lights measured 507 lux (incidence light) and the floor measured 87 lux (reflective light). The floors albedo is: 87 lux/507 lux = 0.17 albedo In other words the floor is reflecting 0.17 (17%) and absorbed 0.83 (83%) of the light.

Summary of Earth’s Energy Budget
We change the Earth’s Energy Budget by:
1) Changing the Earth’s Albedo, changing the Earth’s land surface and land cover
And/or
2) Enhancing the greenhouse effect

Eight “wedges”
Goal: In 50 years, sameglobal emissions as today
What is a “Wedge”?A “wedge” is a strategy to reduce carbon emissions that grows in 50 years from zero to 1.0 GtC/yr. The strategy has already been commercialized at scale somewhere.
1 GtC/yr
50 years
Total = 25 Gigatons carbon
Cumulatively, a wedge redirects the flow of 25 GtC in its first 50 years. This is 2.5 trillion dollars at $100/tC.
A “solution” to the CO2 problem should provide at least one wedge.

Take Home MessagesTake Home Messages
• In order to avoid a doubling of atmospheric CO2, we need to rapidly deploy low-carbon energy technologies and/or enhance natural sinks
• We already have an adequate portfolio of technologies to make large cuts in emissions
• No one technology can do the whole job – a variety of strategies will need to be used to stay on a path that avoids a CO2 doubling
• Every “wedge” has associated impacts and costs

Scenarios:Responding to a Changing Climate
ACTIVITY
Think about:• Which activity/activities you could engage in and
why?• Which activity/activities would be difficult for you to
do and why?• Which activities your community could implement
and why?
Changing the World through Influence
• Liking– People respond more positively to people they view positively.
• Social Proof– People do things they see others do.
• Authority– People tend to obey figures of authority.
• Perceived Scarcity– A perceived lack of something makes that item more valuable.
• Reciprocity– People tend to return a favor.
• Consistency– People do things they see as exemplifying their image of themselves.
(Cialdini, Robert (2008). “Influence: Science and Practice.” 5th ed. Upper Saddle River, NJ: Pearson.)
What I will do today and tomorrow?
Three local climate issues -Individual actions to mitigate or adapt
Example: Recycling reduces energy use and landfill space
ACTIVITY
Individual Community & Regional
• How does this action impact the community?• How can one persuade others to take this
action?• If the community takes this action, does it
impact a broader group of people?• If so, how can this broad group take action to
continue expanding the impact? (regional and beyond)
Citizen Action Examples
• iMatter• Climate education networks• Cornell Citizen Science Clearinghouse• USGS Gauging Stations• CoCoRaHS (Community Collaborative Rain Hail
& Snow Networks) • Earth Force • Hoosier Riverwatch
