Climate Change and Global Health Group

• Research on health impacts, adaptation and mitigation to climate change

• Global perspectives community focus• Rare formation of ”Public Health Climatologists”…..

1. Weather, climate and climate change

Page 7: Climate Change Health Impacts and Adaptation Strategies Joacim Rocklöv, Associate Professor Epidemiology & global health, Umeå University joacim.rocklov@envmed.umu.se.

What is climate?

• Described by physical laws• Complex interaction of atmosphere, sun, vegetation, oceans

and humans• Characterized by different climate types – e.g. arctic,

temperate, tropical, step, monsoonal, arid… • Realisation of weather (rain mm, sun hours, temperature,

wind speed and direction, etc.)• Statistics of weather (long term averages) describes the

climate

Page 8: Climate Change Health Impacts and Adaptation Strategies Joacim Rocklöv, Associate Professor Epidemiology & global health, Umeå University joacim.rocklov@envmed.umu.se.

What is climate change?

• Imbalance of energy in the climate system• Manmade climate change is caused by greenhouse

gases generated by human activities

Epidemiologic research tasks

• Exposure-response relationships between climate variation and health outcomes

• Estimate the current health burden (e.g., annual deaths) attributable to climate change

• Develop scenario-based modelling to project health risks

• Assess health harms and benefits of proposed mitigation and adaptation policy options

Adaptation

= preparedness and prevention of impacts• Education• Policies• InterventionsBoth top-down and bottom-up perspectives are needed:• National policies and strategies• Community involvement• Mixed methods

Page 19: Climate Change Health Impacts and Adaptation Strategies Joacim Rocklöv, Associate Professor Epidemiology & global health, Umeå University joacim.rocklov@envmed.umu.se.

Example - Sweden

Impacts and adaptation strategies:• Health conditions in Sweden are sensitive to climate change, and the

potential impacts was described where such evidence existed in the 2007 National Climate and Vulnerability Assessment (SOU 2007:60)

• Recommendations in form of adaptation strategies was developed in and after the assessment

• Many of which are being emphasized and implemented presently

Examples of undergoing adaptation activities:• Heat waves (warnings system under development)• Borreliosis (increased surveillance and preparedness northwards)• Drinking water (surface water sources; under research; new

technology investments, e.g. UV-light)

Page 20: Climate Change Health Impacts and Adaptation Strategies Joacim Rocklöv, Associate Professor Epidemiology & global health, Umeå University joacim.rocklov@envmed.umu.se.

• Epidemiology of disease directly related to weather and climate extremes (heat waves, floods)

• Epidemiology of disease indirectly related to weather and climate (malaria, dengue, waterborne disease, vole fever etc.)

• Occupational health and productivity• Perceptions, experiences and knowledge of the public to climate

change and health• Projections of disease under climate change scenarios• Research and policies for mitigation and adaptation• ICT and eHealth in adaptation and mitigation• Community adaptation to climate change health impacts (e.g.

early warnings and action plans, mixed methods)

Page 21: Climate Change Health Impacts and Adaptation Strategies Joacim Rocklöv, Associate Professor Epidemiology & global health, Umeå University joacim.rocklov@envmed.umu.se.

Example – mixed methods in adaptation research

A doctoral project in Kenya seeks to:Increase compliance, preparedness and health seeking behaviour to reduce under five mortality in malaria in Kenya by ”epidemic” early warnings disseminated through mobile phones to mothers

Quantitative part:• Develop the early warning by predictions of incidence using lags

of e.g. weather (1)• Evaluate the intervention by a controlled interrupted time series

design (4)Qualitative part:• interviews to help implement the mobile phone intervention

among stakeholder (3)• interviews to seek knowledge on how to develop the messages

and instructions among community participants/mothers (2)
