  • Trouble in the Troposphere
    • The temp. of the Earth is determined by the balance of radiation absorbed
    • About 100 years ago, Swedish chemist Arrhenius predicted the increasng concentrations of CO2 would lead to global warming - which it did
    • The information available is used to construct computer models of the Earth's climate
      • Enormous amount of information
      • Emissions
      • How emissions are expected to change
      • Combined with mathematical descriptions
    • In 1988, the World Meteorological Organization and the United Nations set up in the Intergovernmental Panel on Climate Change (IPCC)
      • Assess  the problem of potential global warming and climate chnages that might occur as a result
      • Produce regular reports that represent the work of thousands of scientists from around the world
      • The 2nd IPCC report in 1995 led to the adoption of the Kyoto Protocol in 1997
        • A total of 169 countries agreed to the proposed limits on emission of greenhouse gases. The agreement came into effect in 2004.
      • Since 1988, the IPCC has collected a huge body of evidence to support the link between increased concentrations of greenhouse gases in the atmosphere and the warming of the Earth
  • Assess  the problem of potential global warming and climate chnages that might occur as a result
