TRANSCRIPT

  • 1.CLIMATE CHANGE: WHAT YOU NEED TO KNOW For more information: African Biodiversity Conservation and Innovations Centre, PO Box 100882 00101, Tel: +254 20 2330014, Mobile: +254 720 529884 , Nairobi, Kenya, www.abcic.org, info@abcic.org A significant change in the state of the climate and/or the variability of its properties and that persists for an extended period and include changes in temperature, rainfall, snow, and wind patterns lasting for decades or longer. Gases in the air around the earth keep it warm, just like a greenhouse keeps the plants inside warm. These natural gases are known as greenhouse gases (Table 1). Over the last 50 years, human beings have produced more greenhouse gases, making the air have a greater greenhouse effect (Figure 1). This is called the enhanced greenhouse effect and has caused the temperature of the earths surface to rise, changing the worlds climate. Natural causes of climate change include changes in the suns energy, changes in ocean circulation, variations in solar radiation and volcanic eruptions. What is climate change? How does it happen? What can you do? The future climate change outlook How can we tell that the climate is changing? Table 1: Greenhouse gases The six main gases are:- CO2 Carbon dioxide (Industries) CH4 Methane (Farms and solid waste landfills) HFCs Hydrofluorocarbons (Industries) PFCs Perfluorocarbons (Industries) N2O Nitrous oxide (Farms and industries) SF4 Sulphur hexafluoride (Industries) Rising sea level Melting of snow and ice e.g. on Mts. Kenya and Kilimanjaro Widespread changes in extreme temperatures Changes in rainfall patterns Shrinking of the arctic sea-ice Prolonged and severe droughts (Figure 2) and floods One of the key factors affecting future climate change is the amount of greenhouse gases emitted into the atmosphere. This depends on among others population growth, economic development, technology and changes in peoples behaviour (Figure 3). Climate takes a while to respond to greenhouse gases; so any greenhouse gases released into the atmosphere now will still affect the climate 50 years to come. Figure 1: Greenhouse effects Figure 2: The main photo shows the impact of climate change on maize in a farm in Kenya. The other shows loss of livestock as a result of extreme drought in the Horn of Africa Use alternative sources of energy, renewable, which will not release harmful emissions such as solar and wind Adopt energy saving tips e.g. using energy-saving appliances like the compact fluorescent light (CFL) bulbs, switching off our electrical appliances when they are not in use Use the public transport; reduce the use of automobiles or use eco-friendly or fuel efficient car Reduce Reuse Recycle: to produce less waste Take part in forest conservation and re-forestation efforts: plant and adopt a tree Practice sustainable and organic agriculture Introduce climate change education in the school curriculum ACKNOWLEDGEMENT ABCIC would like to thank CIC Insurance Group for funding the development of this poster.
