Global warming brings risks of disease, disability: Experts
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, Science Daily reported.
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 coled the report.
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.
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.
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.
