1. ASCL Workshop— Boulder, CO Essential Principals Breakout session: 2E Recorder: Christy Gerrits

2. ASCL Workshop— Boulder, CO Initial Comments ► These are the simplified ideas without prioritization.

3. ASCL Workshop— Boulder, CO Essential Principle #1 ► Complexity  Complexity of Earth’s system is a challenge  Inadequate measurements and chaos contribute to uncertainty  Earth system is nonlinear

4. ASCL Workshop— Boulder, CO Essential Principle #2 ► Linkages (Earth-System)  All life is linked to atmosphere/ocean/land/space/cryo….

5. ASCL Workshop— Boulder, CO Essential Principle #3 ► Energy/Matter/Cycles  Uneven heating of the Earth drives weather and climate  Water cycle  Energy transfers between systems

6. ASCL Workshop— Boulder, CO Essential Principle #4 ► Human Impact  Atmosphere is being altered by human activity  Human activities are being affected by the atmosphere  Humans’ use of natural resources  Humans are able to live because of atmosphere  Economic impact

7. ASCL Workshop— Boulder, CO Essential Principle #5 ► Change Happens  Rate of Change  Human activity accelerates chage  Constantly changing  Atmospheric changes affect living and non-living components  Atmosphere is dynamic

8. ASCL Workshop— Boulder, CO Essential Principle #6 ► Nature of Atmosphere  Earth has only one atmosphere  Air is real and has mass  Atmosphere has structure and characteristics

9. ASCL Workshop— Boulder, CO Essential Principle #7 ► Nature of Science  How do we know what we know  Scientific process  Critical thinking  Earth systems science is interdisciplinary  Laws of Math and Science explain Earth systems  Our understanding and knowledge of Earth systems evolves  Weather and climate are quantified and predicted based on data and models

10. ASCL Workshop— Boulder, CO Essential Principle #8 ► Weather  Affects us daily  Links us to the Earth atmosphere system

11. ASCL Workshop— Boulder, CO Essential Principle #9 ► Climate  Regional vs global  Differentiating climate from weather ► Time scale

12. ASCL Workshop— Boulder, CO Concluding Remarks ► We are still confused about whether we are developing a high framework or a document like Ocean Literacy. ► Are we expressing Climate Change clearly enough? ► How much emphasis should weather have?

13. ASCL Workshop— Boulder, CO Final Step ► At the end of the breakout session, the Recorder should save this file, using the following naming convention: ascl_breakout_.ppt eg., ascl_breakout_2c.ppt ► Once you have saved the file, please transfer it to your session’s OPL, who will upload it for use in the following plenary.
