Rising temperatures as a result of climate change are already exposing people to health risks across the globe, according to a new report from 27 global institutions co-led by UCL researchers. Outdoor workers, people with underlying health conditions, and the urban elderly are especially at risk, according to the findings published in The Lancet.
Professor Hugh Montgomery, (UCL Medicine), Co-Chair of the Lancet Countdown and Director of the UCL Institute for Human Health and Performance, said:
“Exposure and vulnerability to extreme heat is unacceptably high and rising for people all around the world. Heat stress is hitting hard. In high temperatures, outdoor work, especially in agriculture, is hazardous.
“Areas from Northern England and California, to Australia are seeing savage fires with direct deaths, displacement, and loss of housing as well as respiratory impacts from smoke inhalation.”
Leading doctors, academics, and policy professionals from 27 organizations have contributed analysis and jointly authored the report. As members of The Lancet Countdown: Tracking Progress on Health and Climate Change, partners behind the research include the World Bank, World Health Organization (WHO), UCL, and Tsinghua University, among others.
The report investigated the impact of climate change on health in 478 cities across the globe, identifying health impacts including:
The authors say that urgent steps are needed to protect people now from the impacts of climate change. In particular, stronger labor regulations could protect workers from extremes of heat, and hospitals and health systems need to be better equipped for extreme heat.
But the report authors also stress that there are limits to adapting to the temperature increases, so the need for reducing emissions is critical. First author Dr. Nick Watts (UCL Institute for Global Health), Executive Director of the Lancet Countdown, said:
“Whilst the impacts are felt disproportionately by those least responsible for climate change, no country is immune. Our 2018 report makes clear that without urgent action to reduce greenhouse gas emissions, health systems around the world will quickly become overwhelmed by the compounded impacts of a changing environment.”
2018 has been an even hotter year in many parts of the world and another recent report found that this summer’s heat wave was twice as likely to have happened as a result of man-made climate change. With 51 percent of the cities surveyed in the report expecting climate change to seriously compromise their public health infrastructure, the researchers say that the need to ensure health systems, hospitals, and clinics can cope when extreme heat strikes is clear.
Leaders in 65 percent of the cities said they have either already completed or are currently doing climate change risk assessments, but spending on climate adaptation for health is estimated to be just 4.8 percent (£11.68 billion) of all adaptation spending, which is woefully inadequate, the report warns. Professor Anthony Costello (UCL Institute for Global Health), Co-Chair of Lancet Countdown and former Director at WHO, said:
“The world has yet to effectively cut its emissions. The speed of climate change threatens our, and our children’s, lives. Following current trends, we exhaust our carbon budget required to keep warming below two degrees, by 2032.
“The health impacts of climate change above this level above this level threaten to overwhelm our emergency and health services.”
