Dr. kirsty Duncan -CLIMATE CHANGE AND HEALTH

  1. 1. Kirsty Duncan © September 30th, 2013
  2. 2. WORLD ECONOMIC FORUM (2013) -annual survey of more than 1,000 experts released -climate change ranked the “third biggest concern overall” -failure to adapt to climate change listed as the “biggest single environmental hazard facing the planet” -runaway climate change listed as first serious “X factor”, an emerging concern with unknown consequences
  3. 3. A HOTTER WORLD -20th century is the warmest of the last 1,000 years -1980’s, 1990’s, and 2000’s are the warmest decades on record -world’s warmest 13 years of average global temperatures have all occurred in the 16 years since 1997 -warmer temperatures mean increasing droughts, floods, heat waves and other extreme weather
  4. 4. EUROPEAN HEAT WAVE (2003) -death toll of 70,000 -costs exceeded €13 B Source: Wiki (Giorgiogp2) -the duration, geographic scope, impact, and severity of the event were unprecedented in European history
  5. 5. HURRICANE KATRINA (2005) -storm surge of 24-28 ft -43 tornadoes -1.2 million people under an evacuation order -deadliest, costliest disaster in US history at $81 B
  6. 6. INCREASING CLIMATE DISASTERS -each year, 700 to 1,000 events -2011: a year of weather extremes for the US -14 extreme weather events caused losses of $1 B each -worst tornado outbreak in history hit the southern states, with April recording 750 tornadoes
  7. 7. CLIMATE PROFOUNDLY IMPACTS OUR LIVES -climate and weather affect the air we breathe, the food we eat, the water we drink -extreme weather can lead to damaged infrastructure, lost livelihoods, population displacements, and overcrowded conditions which are ideal for the spread of disease -climate variables can affect the emergence of new pathogens and the spread of infectious disease
  8. 8. HEALTH IMPACTS IN A WARMER WORLD -extreme high air temperature and increased air pollutants -cardiovascular and respiratory deaths -extreme weather events and rising sea level -destruction of homes, medical facilities, essential services -from increased risk of infectious diseases to mental health conditions -increasingly variable rainfall -frequency of droughts doubles and duration increases six-fold -increased risk of diarrhoeal disease -transmission of disease -e.g. malaria, dengue, schistosomiasis
  9. 9. TOGETHER WE MUST -recognize that climate change is an emerging and significant threat to public health -raise awareness of this threat, and ensure that health is included in the climate change agenda -continue to explore the links between climate change and human health -work with countries around the world to assess their vulnerabilities, and build their capacity to address climate change
  10. 10. CLIMATE CHANGE -will profoundly affect our economy, health, lifestyles and social well-being -requires moral and intergenerational responsibility -how we respond will define the world our children and grandchildren grow up in -not just an environmental and health issue, but also a human rights issue, an international security issue, and a justice issue What is at stake?
  11. 11. ABSOLUTE URGENCY -2015, the date by which to adopt a universal climate change agreement, is already too late -world tries to hold average climate warming to 2 C, the threshold associated with dangerous climate change -no one yet thinks the world is on a path to stay below an average global rise of 2 C -whether governments accept or minimize the fact that recordbreaking temperatures and extreme precipitation are changing on a global scale, many of the world’s peoples are feeling the impacts now
