...on May 16, 2009 a collaboration between the British medical journal The Lancet and University College London released the first UCL Lancet Commission report, assessing the impact of global warming on global health, and on populations.

Titled Managing the health effects of climate change (.PDF), the year long study highlights the threat of climate change on patterns of disease, water and food insecurity, human settlements, extreme climatic events, and population migration.
