As we move into the second week of COP18, today’s Outreach theme is Climate Change and Health. The World Health Organisation (WHO) give their five key messages on the links between climate change and health. We hear national accounts on the topic from Kenya, Bangladesh and Afghanistan and several articles explore how health and the environment should be considered as part of the post-2015 development framework. Rajendra Pachauri, Chairperson of the Intergovernmental Panel on Climate Change voices his views on the topic, and Outreach interviews Dr Diarmid Campbell-Lendrum, a WHO climate change expert. Other authors emphasise the importance of energy in the climate-health dynamic. And finally, reflections from the negotiations recount some of the action from last week.
