      Objectives of Module 10
      To show that ICTs can be used to address climate change
      To demonstrate why ICTs are a crucial part of the solution – i.e. in promoting efficiency, Green Growth & sustainable development

      What is climate change?
      Any change in climate over time, whether due to natural variability or as a result of human activity

      Discussion
      Is climate change real?
      How is it affecting your country or region?
      Summarize the evidence of climate change in your regions (4 groups)

      The causes of climate change (1)
      The variability in the composition of the constituents of the global atmosphere that affects the energy balance of the planet earth
      When certain gases which absorb solar radiation and emit heat increase in concentration in the atmosphere, this can lead to global warming and climate change
    • 6
      The causes of climate change (2)
      Atmospheric gases that absorb solar radiation more than others retain heat that warms the atmosphere and the surface of the planet
      This leads to global warming and climate change
    • 7
      What is global warming?
      Increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.
      Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century.

      Evidence of climate change comes from:
      Data on global average surface temperatures;
      Global average sea level rise
      The thermal expansion of the water in the oceans plus the amount of glacier ice that has melted and that has led by extension to a rise in the level of the oceans around the world

      The impact of climate change (1)
      The efficiency of CO2 sinks is down
      Atmospheric CO2 is being added at the rate of 2ppm annually
      Methane up after 10 years of being stable
      Carbonate calcium walls of marine life are down. The oceans are getting more acidic.
    • 35
      The impact of climate change (2)
      Oceans have warmed up faster
      Arctic sea ice is at a low peak
      Greenland ice sheets have decreased in size
      Fossil fuel emissions are above worst case scenarios
      Deforestation emissions continue and are high

      In the Asia Pacific region, the following changes are anticipated (1):
      By the 2050s, freshwater availability in Central, South, East and South-East Asia, particularly in large river basins, is projected to decrease.
      Coastal areas, especially heavily populated megadelta regions in South, East and South-East Asia, will be at greatest risk due to increased flooding from the sea and, in some megadeltas, flooding from the rivers.
    • 39
      In the Asia Pacific region, the following changes are anticipated (2):
      Climate change is projected to compound the pressures on natural resources and the environment associated with rapid urbanisation, industrialisation and economic development.
      Endemic morbidity and mortality due to diarrheal disease primarily associated with floods and droughts are expected to rise in East, South and South-East Asia due to projected changes in the hydrological cycle.
    • 40
      In small island states the following changes are predicted
      Sea level rise is expected to exacerbate inundation, storm surge, erosion and other coastal hazards, thus threatening vital infrastructure, settlements and facilities that support the livelihood of island communities.
      Deterioration in coastal conditions, for example through erosion of beaches and coral bleaching, is expected to affect local resources.
    • 41
      In small island states the following changes are predicted
      By mid-century, climate change is expected to reduce water resources in many small islands, e.g. in the Caribbean and Pacific, to the point where they become insufficient to meet demand during low-rainfall periods.
      With higher temperatures, increased invasion by non-native species is expected to occur, particularly on mid- and high-latitude islands.

      Solutions going forward: two issues & how to deal with them
      Increasing demand for energy
      Will need both fossil fuels & new and alternate energy
      Need to limit GHG emissions
      Need to replace emissions from fossil fuel emitting sources
    • 43
      We have a problem!
      Renewables are plentiful but require massive investment to fully replace fossil fuels
