  1. Climate and Global Warming Extreme weather events Humidity ,floods, storms Crops prices and wild fires

  2. Green house gases form a blanket around earth trapping energy in the atmosphere causing it to warm (known as the greenhouse effect)

  3. Climate changeThe facts • Sea levels are rising due to water expanding as temperatures rise • Rising temperatures accelerate melting adding extra water to the seas • Rising sea level lead to higher tides and storm surges • Climate can be natural but what’s happening now can’t be explained by natural forces only

  4. Human Causes of Climate Change

  5. Who is to Blame? • Humans largely responsible for recent climate change • Human activities releasing large amounts of CO2 and other green house gases into the atmosphere • Majority of green house gases com from burning fossil fuels to produce energy, deforestation industrial processes – some agricultural practices also emit gas into the atmosphere

  6. Effects of Climate Change • Increasing presence of pests and diseases • Sea level rises loss of beaches • Coastal communities – Hurricanes intensified • High temperatures affect growth and production of crops, and trees • Northeast – More frequent heat waves higher threat to human health, farms, aquatic life, damaging livelihoods and regional economy

  7. Effects on health • Longer Heat waves = heat related illnesses and deaths • Heat stroke and dehydration, most common cause of heat related deaths • Skin Cancer • Unhealthy air and pollutants • Spreading diseases –ticks and mosquitoes

  8. Young people, old people and people with medical conditions are more vulnerable to heat related illnesses • Electricity use higher during summer to run air conditioning causes more air pollution • Extreme weather causing injury and death

  9. Availability – food and water , contamination and water borne diseases • Interruption of communication and health care services • More stomach and intestinal illnesses • Mental health impacts depression and post traumatic stress disorder • As quality of air drops ( Lung/Cardiovascular) • Premature Death, asthma • Humidity – warm stagnant air ozone • Inhaling particles exacerbate respiratory diseases

  10. Enhances the spread of diseases causing agents pathogens-ticks , mosquitoes • Salmonella and Bacteria related to food poisoning bacteria grow rapidly in warm environments • GI distress severe death • Food borne illnesses • Flooding overflow from sewage treatment plants into fresh water sources contaminate crops with pathogen containing feces

  11. advocacy • The choices we make today will affect the amount of green house gases we put in the atmosphere in decades to come • Climate change affects everyone, Our lives are connected to climate change interventions • support energy efficiency • Be an advocate of climate change IPCC, Climate Change 2007: Impacts, Adaptation and Vulnerability (Cambridge, U.K.: Cambridge University Press, 2007).
