Climate change health risk is a ‘medical emergency’, experts warn

Extreme weather events such as floods and heat waves bring rising risks of infectious diseases, poor nutrition and stress, the specialists said, while polluted cities where people work long hours and have no time or space to walk, cycle or relax are bad for the heart as well as respiratory and mental health.

Almost 200 countries have set a 2 degrees C global average temperature rise above pre-industrial times as a ceiling to limit climate change, but scientists say the current trajectory could lead to around a 4 degrees C rise in average temperatures, risking droughts, floods, storms and rising sea levels.

“That has very serious and potentially catastrophic effects for human health and human survival,” said Anthony Costello, director of University College London’s (UCL) Institute for Global Health, who co-led the report.

“We see climate change as a major health issue, and that’s often neglected in policy debates,” he told reporters at a briefing in London.

The report, commissioned and published by The Lancet medical journal, was compiled by a panel of specialists including European and Chinese climate scientists and geographers, social, environmental and energy scientists, biodiversity experts and health professionals.

It said that because responses to mitigate climate change have direct and indirect health benefits – from reducing air pollution to improving diet – a concerted effort would also provide a great opportunity to improve global health.

The report said direct health impacts of climate change come from more frequent and intense extreme weather events, while indirect impacts come from changes in infectious disease patterns, air pollution, food insecurity and malnutrition, displacement and conflicts.

“Climate Change is a medical emergency,” said Hugh Montgomery, director of UCL’s institute for human health and performance and a co-author on the report. “It demands an emergency response using technologies available right now.”

The panel said there were already numerous ways to bring about immediate health gains with action on climate change.

Burning fewer fossil fuels reduces respiratory diseases, for example, and getting people walking and cycling more cuts pollution, road accidents and rates of obesity, diabetes, heart disease and stroke.

Cardiovascular disease is the world’s number one killer, leading to some 17 million deaths a year, according to World Health Organization data.

“There’s a big (energy) saving in people using calories to get around, and there are some immediate gains from more active lifestyles,” Montgomery said. -Reuters
