How does climate change affect our health?

There are increasing warnings of the negative effects of climate change. Researchers have now found that human health is already negatively impacted by the effects of climate change. The health burden will continue to increase in the future.

In their joint current study, scientists from University College London and other research institutions found that climate change is already having a negative impact on human health. The doctors published the report in the English language journal "The Lancet".

Heat waves in Europe are increasing

The negative effects of climate change range from heat waves in Europe to increasing cases of dengue fever in the tropics, the experts say. Billions of hours worked in agriculture have been lost in the high temperatures and, of course, harvests are also affected. The current report was prepared by 150 experts from 27 universities and institutions such as the World Health Organization and the World Bank. Efforts to combat climate change must be tripled or people must face catastrophic climate change, the experts warn. We can no longer delay climate change, this situation can no longer be ignored, according to the WHO communication.

What are the effects of global warming?

The report outlines the effects of global warming on health in critical terms. A rapidly changing climate has bad impacts on every aspect of human life by exposing vulnerable populations to extreme weather, changing the patterns of infectious diseases, and affecting food security, clean drinking water, and clean air, the report said.

Global warming endangers national health systems

The UN said on Tuesday that measures to reduce CO2 emissions must be tripled in order to avoid catastrophic warming. International climate negotiations should resume in Poland on Monday. The lack of progress in containing global warming threatens both people's lives and national health systems, the researchers say.

Europe and the eastern Mediterranean are particularly hard hit

A survey of executives from nearly 500 cities in the report found that half of respondents expect their public health infrastructure to be severely impacted by climate change, leading to systemic failures such as hospital decommissioning. A heat wave in Europe this summer was linked to hundreds of premature deaths in the UK alone. According to the report, populations in Europe and the Eastern Mediterranean are at higher risk than in Africa and Southeast Asia, as the proportion of vulnerable and elderly people living in cities is high.

How does the heat affect you?

Very hot climatic conditions directly damage health through heat stroke and dehydration, but the aggravation of diseases such as heart diseases is also very dangerous. Heat also increases air pollution and mental health problems. Many communities are unprepared for the sustained increase in the frequency, intensity, and duration of heat waves, experts say. Relatively small changes in temperatures and precipitation can lead to major changes in the transmission of infectious diseases that spread via water and mosquitoes. The portability of the dengue virus reached a record level in 2016, for example. The risk of cholera also increased in regions such as the Baltic States, where the sea warmed up quickly.

People now have to take countermeasures

The report clearly shows that climate change is already having a direct impact on health. Measures against climate change must be prioritized if the potentially devastating effects on the planet and the health of future generations are to be reduced. (as)
