In early December, the Lancet Countdown published a new report on the global link between climate change and health. Annette Peters researches the consequential interconnections at the Helmholtz Zentrum München.

Ms. Peters, environmental pollution such as exhaust fumes or contaminated water is bad for our health. That's easy to grasp. But why is climate change harmful to our health?

There are many different consequences of climate change that directly impact our health. Heat waves, for example, are occurring more frequently and putting stress on our cardiovascular systems. People who live in cities, where heat waves are felt more keenly, are especially affected by this development. New infectious diseases are spreading, for example through the tiger mosquito, which now enjoys conducive living conditions here in Germany. We are also looking at how our mental health is being affected. Does the impact go beyond just not being able to think so well when it’s hot outside? On hot days we’re also seeing a higher number of heart attacks among people with diabetes and high cholesterol levels. Overall, changes in our climate directly affect our health in a wide variety of ways.

Which of these topics are you researching?

My team and I are primarily researching the biological processes that occur in the body on hot days. We are especially interested in looking at what happens on a molecular level when several hot days occur in a row. We also want to find out how heat – together with air pollutants and noise – impacts urban environments, in other words how these factors interact to affect our health.

 

Do you have any findings already?

We are able to demonstrate, for example, that the negative effects of air pollutants on the human body increase when temperatures rise. Heat has an intensifying effect, which means that pollutants in the air will pose a greater threat to us as climate change increases.

Eckart von Hirschhausen has translated and summarised the results of the Lancet Countdown 2020 in this video (German). In it, he emphasises how central this topic is to our health and what we can do now to ensure that we continue to have healthy people on a healthy planet in the future.

 

Are there any lessons we can learn from the current health crisis of the COVID-19 pandemic that are applicable to climate protection, too?

Yes, certainly. For one thing, we are currently seeing that things previously considered to be set in stone can absolutely be changed. For example, it has been quieter and the air has been cleaner in many places throughout cities in recent months. Another thing is that we’ve seen how drastic and far-reaching such global events can be. While climate change is happening less abruptly than the pandemic, its effects will also be serious, which is why it’s so important that we take timely and decisive steps to counteract them. We still have the possibility to keep the effects of climate change within tolerable limits.

The 2020 Lancet Countdown report was presented on December 3, 2020. More information: https://klimagesund.de/
