  • In the past, climate fluctuated naturally in an elegant cycle of warm and cold periods defining the agriculture, civilization and possibly tools that man used. For quite sometime now, the climate has been changing at an unnerving pace. Globally, the mean temperature has gone up by three-fourths of a degree- centigrade but some of the Earth’s remote spots have warmed much more, so that ---
  • Global Average Temperature Over the past 100 years there has been an increase in global average temperature of more than one degree Fahrenheit (0.6°C). While the record shows a great deal of variability, the upward trend is unambiguous. Most of the warming occurred during two periods, 1910 to 1945 and 1976 to the present. The rate and duration of the 20 th century warming has been much greater than in any of the previous nine centuries (i.e., over the last 1,000 years). Globally, the 1990s has been the warmest decade, and 1998 and 2001 the two warmest years in the last millenium. Night-time minimum air temperatures over land have increased at the greatest rate; this has lengthened the frost-free season in many mid-and high-latitude regions.
  • Considering the consequence of a higher GHG level at 450ppm…….
  • The short-term trends of relative sea level change from tide-gauge data indicate spatial and temporal variation. The general trends for the period 1948 to 1993 is a relative rise of sea level in the Manila, Legaspi and Davao stations and a relative fall in Cebu and Jolo stations. In Manila Bay, In Jolo and Cebu, the tide-gauge data indicate uplift of landmasses. The tide-gauges here are set on rocky foundations. In contrast, in Manila Bay, Legaspi and Davao, the tide-gauges are situated on Holocene coastal deposits. A noticeable change in the rate of sea level change, apparently occurring synchronously across the stations, took place in the late 1960’s. Except for Cebu, acceleration of sea level rise is indicated. In Davao and Manila the previous rate of rise of 2.1 mm/y increased to 3.2 and 20.0 mm/yr, respectively. In Manila, extraction of groundwater has been identified as the major contributor to the elevated rates of relative sea level rise (Siringan and Ringor 1998). In Legaspi, the flat trend shifted to 5.9 mm/yr. In Jolo, the relative fall of 3.8 mm/yr became a relative rise of 0.4 mm/yr. In Cebu, the only station with a different signal, shows an increase in relative fall from 2.9 mm/yr to 3.5 mm/yr. Local tectonic and/or anthropogenic influence is indicated by the non-uniform magnitude of change across the stations.
  • And these are not minor issues. Diseases that are sensitive to climate include some of our biggest killers. These include d iseases such as malaria and diarrhea. They also include risk conditions such undernutrition, the single largest contributor to the global burden of disease. Together, these kill many millions each year, especially children in developing countries.
  • Climate change will affect, in profoundly adverse ways, some of the most fundamental determinants of health: food, air, water. This figure shows that climate change impacts on health both directly - for example through heatwaves, floods and storms, but also indirectly, through effects on infectious disease, on water availability, and on agricultural production.

    1. 1. CLIMATE CHANGE Presented by: JOHN JULIUS BERMEJORT3 at Pateros Rescue Unit, LGU Pateros NCR
    2. 2. What is climate change?“Change in climate which is attributeddirectly to human activity that altersthe composition of the globalatmosphere and which is in addition tonatural climate variability observed overcomparable time periods.” - (United Nations Framework Convention on Climate Change [UNFCCC])
    3. 3. Scientists now agree that most of the global warmingtoday have been caused byHumanActivities
    4. 4. Human activities that lead to the increase in concentration of greenhouse gases (GHGs)include:  Worldwide deforestation  Increasing industrial activity  Motor vehicle emission  Waste management practices  Intensive agriculture
    5. 5. Waste as a source of GHG emissions Decaying solid waste in landfills emits methane
    6. 6. Waste as a source of GHG emissionsDecomposing waste in water also emit methane KLIMA

    9. 9. What is global warming? Global warming refers to the increase in the earth’s mean temperature due to the so-called enhanced greenhouse effect.
    10. 10. How do GHG influence climate change? The higher the concentration of greenhouse gases in the atmosphere, the stronger the greenhouse effect.

    14. 14. GLOBAL STATUS Scientists’ report : By 2050, the world would reach the tipping point of irreversible climate change• weather patters will be disrupted, causing stronger typhoons Ice caps will melt, raising sea levels by 6 to 7 meters
    15. 15. Evidence indicated that people living in low-income countries are 4 times more likely todie from extreme natural disasters thanthose in high-income countriesWomen and men suffer different negativehealth consequences following a disaster
    16. 16. Manifestations of Climate Change … Melting of Glaciers Arctic sea ice area decreased by 2.7% per decade
    17. 17. Greenlands glaciers are melting into the sea twice as fast asthe previously believed rate of four miles per year.
    18. 18. The Thames Barrier, a major flood defense systemin London designed to be used once every two tothree years is now being used six times a yeardue to increased rainfall.
    19. 19. Sea Level Rise Possible Impacts • Increased coastal flooding • Enhanced coastal erosion • Salt-water intrusion • Impacts of storm surge magnified
    20. 20. Impact of sea-level rise in the Philippines Effect on coastal populations, habitats and infrastructures Intrusion of sea water to upstream of rivers resulting in: loss of ground water supply loss of eco-systems loss of livelihoods Above are significant : 7,107 islands 36,289 km of coastline many river systems

    30. 30. Health Impact (Global)• 1.8 M people die from diarrheal diseases• 1.5 M deaths in the 0 – 5 y.o. age group every year of 5,000 child deaths/day• 88% attributed to unsafe water, inadequate sanitation and hygiene• 1.1 billion lack of access to an improved drinking water supply
    31. 31. Major killers are climate sensitive diseases- Each year: - Undernutrition kills 3.7 million - Diarrhea kills 1.8 million - Malaria kills 1.1 million Each of these is highly sensitive to temperature and precipitation
    32. 32. Health workforce are central toidentifying potential health risks from natural hazards and promoting personal and community risk reduction measures It is essential to strengthen disaster preparedness in health sector
    33. 33. Health facilities whose services remainaccessible and functioning, at maximumcapacity and within the same infrastructure,during and immediately following disasters,emergencies or crises is greatly impaired
    34. 34. Hospitals/healthfacilities destroyed ordamagedPeople left withoutemergency carehospitals and healthfacilities fail tofunction.More without publichealth and clinicalservices whenoperations are
    35. 35. All disasters are health issue, and damage to health systems affects every part of society and the nations as a whole.

    50. 50. Promote Public Awareness Educate yourself, you family, your friends, your co-workers and everyone you meet. The more people are aware of the issues the more likely they are to make decisions that will be constructive! Be ac tive - Speak up in a positive way in your local community and organization and help others to commit to reducing greenhouse gas emissions.

The less energy we use, the better. • By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually.
