Climate change and global health
Four steps
• Realize how profound the anthropogenic climate changes are
• Understand the impact of these changes on global health
• Take advantage of the different roles we have as health professionals
• Act

Climate and health
Global health threads by climate changes are primarily a consequence of
• Damages after hurricanes and cyclones
• Homelessness for millions after floods
• Climate refugees, unsustainable migration
• Disintegration of civil infrastructures
• Shortage of drinking water
• Starvation <= population↑, food production↓
• Expanding areas of vector-borne diseases
Commitment of health professionals
Health professionals have four roles
• They are members of strong professional international networks e.g. WMA.
• They are professional health managers
• They contribute with new knowledge through research
• They are citizens as all other citizens
We can and we should act adequately and timely within each of these four roles
Lidegaard & Ricketts (Eds). Climate change and health care. WMA 2009
Commitment of health professionals
Professional networks
• Inform about short- and long term global health impact of climate change
• Stress that climate change is the biggest global health threat of the 21st century
• Demand immediate mitigation initiatives
• Initiate research in health consequences of climate change
Costello et al. Lancet 2009; 373: 1693-1733
Commitment of health professionals
Health managers and advisors• Inform about short- and long term local
health impact of climate change• Focusing on initiatives which improve
public health and global climate at the same time (less use of fossil fuel, diet changes, physical activity)
• Disclose personal views on climate change
Costello et al. Lancet 2009; 373: 1693-1733
Commitment of health professionals
Research in climate and health
• European health consequences of
- increased temperature
- changed precipitation pattern
- melting glaciers
Aletsch Glacier (CH)
Commitment of health professionals
Research in climate and health
• European health consequences of
- increased temperature
- changed precipitation pattern
- melting glaciers
- more frequent extreme weather
• European health benefits of mitigation initiatives
• European adaptive health initiatives
Research in climate and healthEuropean health benefits of mitigation initiatives
• Physical activity from car to bicycle
Adiposity, diabetes, CaVD, cancer
• Changed diet from meat to vegetables
Adiposity, diabetes, CaVD, cancer
• Urban transportation (car transp ->bicycling)
Airway diseases, adiposity, CaVD, cancer
• Reduced consumption – environment
Male reproductive function (TDS)
Research in climate and health European adaptive health initiatives
• Mobile emergency units
to areas hit by extreme weather events
• Modules in all health educations on climate change and health consequences
• Reproductive perspectives impact of access to safe contraception and legal abortion for controlling population growth
• Physical activity – CaVD, cancer, DM, quality of life, life length,
Research in climate and health Professional health organisations
• Construction of sustainable health institutions
buildings, equipment, food, transportation
• Electronic real time video communication in replacement for distant personal meetings
• Waste policy re-cycling equipment
• Environmental footprint of health care sector describe, integrate and recommend green professional practices.
Commitment of health professionals
As member of the general society
• Limiting long distance flights
• Reduce private fossil fuel consumption
• Reduce energy consumption (50%)
• Combine physical activity with personal transportation (e.g. bicycle transportation)
• Learn your children to behave responsible
• Involvement in local initiatives
