Human and Nature

Review of last lecture Large spread in projected temperature change comes from uncertainties in climate feedbacks Main climate feedbacks for global warming: ice- albedo, temperature, water vapor, cloud, aerosol, carbon cycle Abrupt climate change and tipping points

Life cycle of the Sun and Earth Length of human history

Cradles of civilization

Were the ancient people stupid? ?

Ancient Greece : Art God of Wine (600BC) Bell krater depicting the return of Persephone (440 BC)

Ancient Greece: Art ~130BC~400BC

Ancient Greece: Philosophy & Science

Ancient China: Art Jade dragon, 3000BC Bone flute, 6000BC Can still play

Ancient China: Art Silk clothes, 200BC Weight 49g Bronze art, 400BC

Ancient China: Philosophy

Egyptian pyramid ( BC) How were they constructed?

Dujiangyan irrigation system 250BC ( 都江堰 ) Eliminate floods. still in use today to irrigate over 5,300 km 2 of land. Survived the big earthquake in 2008.

Ancient view of nature: Quite modern Basic elements of natural systems Wind Earth Fire Water Respect and be in harmony with nature (Conservation of monmentum) (Conservation of mass) (Conservation of energy)

Video: Feelings of mountain and water QSvGQhttps:// QSvGQ

The industry revolution James Watt ( ) Watt’s steam engine (~1770)

Positive effects of industry era: Abundance of materials

Positive effects of industry era: Convenient transportation & communication

Negative effects of industry era: Environmental issues

Negative effects of industry era: Competition, unsatisfied, stress

Possible solutions Take advantage of the positive effects Try to avoid the negative effects Enjoy the bare necessities Be independent

Vision: Setup of the National Parks John Muir ( )

Vision: Enjoy the bare necessities

Sustainability Human rights and dignity Accountability Efficiency Investment in the future Vision: Green Economy

Summary Cradles of civilization. Were the ancient people stupid? Ancient view of nature Industry revolution: positive effects and negative effects Vision: environmental protection and enjoy the bare necessities
