1 ASCL Workshop— Boulder, CO Essential Principals Essential Principals The atmosphere and humans are inextricably linked (humans are dependent upon and affect the atmosphere) Breakout session: 8c Recorder: Rhonda Spidell

2 ASCL Workshop— Boulder, CO Fundamental Concept #1 ► The interconnected relationship between humans and the atmosphere is complex and difficult to isolate. ► ► (scrap this point but somehow rescue that the relationship is complex ► ► use quantify or limit)

3 ASCL Workshop— Boulder, CO Fundamental Concept #2 ► Human beings are dependent on and vulnerable to Earth’s atmospheric processes. ► ► Humans breathe to inhale oxygen and release carbon dioxide and are dependent on water distributed through the hydrologic cycles which determine human activities. Living organisms including humans depend on the atmosphere and cause changes to the atmosphere. *vulnerable to natural hazards

4 Fundamental Concept #3 Living organisms including humans depend on the atmosphere and cause changes to the atmosphere. ASCL Workshop— Boulder, CO

5 Fundamental Concept #4 ► ► Human activities, such as changes in land use and burning fossil fuels, alter the atmosphere, affecting human and ecosystem health and climate. ► ► Human activities, such as burning fossil fuels and increasing the amount and variety of chemicals released into the atmosphere, reducing the amount of forest cover, and rapidly expanding farming and industrial growth have changed Earth’s land, oceans, and atmosphere and altered Earth’s climate. Atmospheric contamination degrades human health. ► ► The increase in global average temperatures since the mid-20th century is very likely due to the observed increase in human-induced greenhouse gas concentrations in the atmosphere, primarily from fossil fuel combustion and deforestation. (Based on IPCC, 2007) ► ► Add Goddard examples

6 ASCL Workshop— Boulder, CO Fundamental Concept #5 ► ► Individual and societal activities are affected by weather forecasts and climate expectations. Many decisions are based on assumptions of a stable climate. ► ► (some reservations about the second sentence) ► ► some consensus about an educated citizenry and decision making---local to global
