By Robin McKie Paris summit must recognise spreading health danger posed by global warming, says Wellcome Trust director

Epidemics of dengue fever and other tropical diseases could soon affect people in Britain because of global warming, one of the world’s leading medical experts has warned. Jeremy Farrar, director of the Wellcome Trust, said he also believed the planet is already being affected by many other serious health threats triggered by climate change – including malnutrition and deaths from air pollution.

However, these dangers were not being given proper attention by world leaders, added Farrar, an expert on infectious diseases. Climate negotiators heading to Paris this month did not appear to have understood the widespread impact that global warming has already had on Earth. “I don’t think the health community has had a big enough input into climate talks,” Farrar told the Observer. “Bodies like the World Health Organisation have not made their voices heard.”
