The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) in 1988
� More damage because of storm and other weather related calamities to building, transport, energy, communication and water services
� Greater frequency and severity of extreme weather events: Heatwaves, fires floods, landslides, droughts and storm surges will become significantly more frequent
� Blackouts due to peak energy demand for air conditioners will become common in spite the fact that there will be less energy use for winter heating
� Coastal flooding: Projected global warming this century is likely to trigger serious consequences for humanity and other life forms, including a rise in sea levels of between 18 and 59 cm which will endanger coastal areas and small islands

The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) in 1988
� Severe water shortages
� Reduced agricultural production due to drought and fire
� Risk for peace and security due to increased possibilities of wars for claims for water, land and other resources
� Increase in refugees from the effects of climate change
� Increase in mosquito, food and water-borne diseases
� Loss of biodiversity

Countermeasures against Global Warming and Climate Change
� Reduction of CO2 production and carbon footprint --- Public transportation vs individual traffic – Energy management/conservation
� Early warning systems and forecasting
� Change in the food and meat production
� Crop: variety, genetic modification, planning, irrigation modification
� Vector control

Global Warming, Climate Change and Disaster
� Climate change can viewed as challenge and chance for mankind
� Quadrupling energy efficiency
� Introduce carbon emission rights for everyone equal and just
� Exploitation of existing carbon-free technologies
� Raising awareness in the public and take a more scientific approach – not ideological approach-
� Radical change in philosophies and politics
� Emphasis on equality and justice
