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.

  5. The causes of global changes • solar output • plate tectonics • Volcanism • proliferation and abatement of life • meteorite impact • resource depletion • changes in Earth’s orbit

  6. 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!!!

  7. How global changes influence the society in variety of areas Globalizationglobal integration global financial crisis

  8. Predict the future environmental development • global warming effect • Carbon dioxide • Pollution damage • Dirty bombs • Hydrogen fuel cells for cars • nuclear power • Water
