Global Changes

TV forum on Discovery


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
