There was a notable first in the latest Conference of Parties on climate change, held this month in Dubai, as the world gathered once again to seek agreement on how to curb global warming.
Public health in the climate change era became the subject of a day’s discussion at COP28. It came around a century after the climate was first linked to the spread of disease in an article about smallpox published by The American Public Health Association in October 1926.
Climate change was not a recognised concern back then. The COP series of meetings on it started in 1995. Until this year, the relationship between climate change and health has become an integral part of the agenda at these set-piece international events.
The US Special Envoy for Climate, John Kerry, remarked, "I'm astonished it's taken this long to get health on the climate discussion table."
It used to be customary for only environment ministers to attend the COP summits. This year was the first time that health ministers attended in significant numbers.
The conference president, Dr. Sultan Al Jaber, said: "The impact of climate change is already at our doorstep and has become one of the biggest threats to human health in the 21st century," adding, "Governments now realise that health is a critical element in climate action."
Many people are not fully aware of the close relationship between the environment and health. According to the World Health Organisation, the number of deaths is expected to increase by 250,000 annually in the coming decades due to climate change — especially in the case of natural disasters that may lead to the spread of infectious diseases.
