Global warming killed 150,000

GLOBAL warming killed 150,000 people in 2000 and the death toll could double again in the next 30 years if current trends are not reversed, the World Health Organisation has warned.

A heat wave killed 20,000 people in Europe alone this year, the WHO said, launching a book on health-weather links at a UN environment conference.

Climate change, linked by scientists to human emissions of gases such as carbon dioxide from cars and factories, is causing more frequent floods and droughts and melting ice caps.

“An estimated 150,000 deaths ... were caused in the year 2000 due to climate change,” the study said. A further 5.5 million healthy years of life were lost worldwide due to debilitating diseases caused by climate change, it said.

“The 1990s were the hottest decade on record and the upward trend in the world’s temperature does not look like it is abating,” it said. “In Europe this past summer an estimated 20,000 people died due to extremely hot temperatures.”

The situation will worsen if climate trends continue, WHO experts said at a news conference to launch the book.

“We see an approximate doubling in deaths and in the burden in healthy life years lost,” by 2030, said WHO scientist Diarmid Campbell-Lendrum.

The book estimated climate change was to blame for 2.4% of cases of diarrhoea because, Campbell-Lendrum said, the heat would exacerbate bacterial contamination of food.

Climate change was also behind 2% of all cases of malaria, because increased rainfall created new breeding grounds for disease-carrying mosquitoes, he said.

But he acknowledged global deaths from climate change were minuscule compared with the total number of deaths a year, which the WHO puts at 56 million. About 10 times more people die each year from tobacco-linked illness, he said.

“That doesn’t make it more acceptable and the fact is it’s likely to get worse,” he said. “One of the points about climate change is that people who are affected don’t have the choice to stop smoking.”

While halting global warming was the only long-term cure, immediate actions to fight disease and improve health service access would also help, Campbell-Lendrum said.
