The human beings are facing many global changes • population • Climate changes • Global warming • Pollution • Health • resource use • Transportation • sea ice loss & sea-level rise • biological diversity
Two main global changes Climate changes • greenhouse gas emissions • pollution - Water management Global warming • global dimming • temperature increases • weather pattern changes
The history of global changes • In 1980, the World Climate Research Program (WCRP) • In 1987, the International Geosphere-Biosphere Program(IGBP) • In 2001, in Amsterdam, the landmark science of conference of IGBP, WCRP, IHDP • In 2012, in London, another major science conference, Planet Under Pressure: new knowledge towards solutions.
The causes of global changes • solar output • plate tectonics • Volcanism • proliferation and abatement of life • meteorite impact • resource depletion • changes in Earth’s orbit
The physical evidence for global changes -The advent of agriculture (10000 years ago) -industrial revolution (1750) -Haber-Bosch process (1909) • population more than doubled (1950-2010) - human population - urban population & rural population • Chemical composition of the atmosphere Greenhouse gases in increasing fast!!!
How global changes influence the society in variety of areas Globalizationglobal integration global financial crisis
Predict the future environmental development • global warming effect • Carbon dioxide • Pollution damage • Dirty bombs • Hydrogen fuel cells for cars • nuclear power • Water
