Climate change and health are inexorably linked. The WHO estimates that 7 million premature deaths annually are linked to air pollution and between 2030 and 2050 climate change is expected to cause approximately 250,000 additional deaths per year, with direct damage costs to health estimated at between US$2-4 billion/year by 2030. If climate change is not brought under control, health problems from unclean air, water unsafe to drink, insufficient food and lack of secure shelter will only be exacerbated, leaving those developing countries that are most exposed least able to cope.
