Environmental changes pose a significant threat to global health

  • Climate change
  • Marine pollution
  • Urbanisation
  • Ozone depletion
  • Biodiversity loss
  • Soil degradation
  • Air pollution

Climate change could be the biggest global health threat of the 21st century.

‘Global mean sea level will continue to rise during the 21st century. Under all RCP scenarios the rate of sea level rise will very likely exceed that

  • bserved during 1971–2010 due to increased ocean warming and

increased loss of mass from glaciers and ice sheets.’ (IPCC 2013)

Future challenges

To engage in this increasingly-important topic area, we will need to generate skills and methods in:

  • 1. Well-coordinated interdisciplinary research (including collaboration

with some unfamiliar earth-system sciences).

  • 2. Assessing causal relationships within a systems-change context:

How do large-scale changes in ecosystems affect wellbeing, health and longevity of whole communities and populations?

  • 3. Scenario-based risk assessments (forecasts) of climate change:

Requires construction of models which are both sensible and realistic. 4. Economic research relevant to climate and health 5. Formulation and evaluation of community-based adaptive (coping) strategies. 6. Communications research

CONCLUSIONS

  • CC is, arguably, the biggest challenge to

global heath in the 21th century.

  • Accruing evidence indicates an increased

CC-related disease burden.

  • We must tackle this formidable, increasingly

important public health challenge.

  • There is an urgent need to train more

ECRs/students in this emerging field.

  • Funding is clearly needed to support the

research agenda.
