Climate change: more and more people are exposed to extreme heat


More and more people are struggling due to heat waves and climate change, with health problems. Especially in cities the situation is exacerbated. A new international study shows. Therefore, the missing hours of employees are piling up.

Climate change threatens according to a study, the health of more and more people. Accordingly, 18 million more people at risk the heat were in last year’s waves exposed as 2016. In comparison to the year 2000, there were 157 million more. The report, a number of scientific institutions in the journal The Lancet.

As the heat of people that are over 65 years of age, live in cities, or Diabetes, a cardiovascular disease or chronic respiratory problems are at risk in this context. The climate change, are exposed according to the authors, especially a lot of people, because the temperatures are rising in the densely populated regions of particularly strong: 0.8 degrees Celsius from 1986 to 2017. In the same period, the global average temperature rose by 0.3 degrees Celsius. The researchers also expect to see a spread of tropical diseases.

Heat stress coupled with poor air quality in cities

The heat is often associated with air pollution in the cities. 97 percent of the studied cities in countries with low-and middle-income levels do not meet the air quality guidelines of the world health organization (WHO).

The warming also leads to more work hours for the heat to fail. In 2017, there were 153 billion hours worldwide, 62 billion more than in the year 2000. In addition, other economic losses: In the past year, 712 extreme weather events led to a global loss of 326 billion dollars (approximately 288 million Euro), almost three times the amount of 2016.

Health risks rise

Today’s changes in heat waves, and of working assets to give advance warning of the increased and overwhelming impact on public health, are expected if temperatures continue to rise, Hilary Graham, of the University of York in a Lancet quoted message.

But there are bright spots, write the authors. So, global coal consumption has fallen since 2013. The performance of the 2017 power plants built on is divided into 157 gigawatts from renewable energy and 70 GW from fossil fuels. Exciting Trends in key areas of health, including the phase-out of coal, the use of healthier, cleaner mode of transport and the adaptation of the health system, to justify a cautious optimism, the researchers write.

For the project The Lancet Countdown: Tracking Progress on Health and Climate Change have done, among other things, the United Nations and 27 leading research institutions. The project is based on the expertise of Climate scientists, physicians, Ecologists, mathematicians, geographers, engineers, energy-, food-, livestock – and transport experts, Economists, Social and political scientists as well as members of the health authorities.
