The devastating floods in Valencia in October 2024 and the rainfall alert issued on September 28, 2025, showed that the way we communicate risks can make a difference, for better or for worse. This article presents eight key points for journalists, public officials, communicators, and anyone else interested in communicating better about floods and other crises.
This guide is designed for journalists who cover stories about risks in any sector: health, environment, artificial intelligence etc. You will identify the concepts that will help you explain, for example, why false flood alarms occur, the pros and cons of installing a nuclear plant in a certain area, or the uncertainty of a study that finds a particular diet increases the risk of developing cancer.
The risk of an adverse reaction to a vaccine and the risk of not evacuating a flood-prone area have something in common: both are risks, though very different ones. While one refers to a numerical probability, the other refers to a potential consequence. Here, we explore six different meanings of the word “risk” in headlines. These examples will help you explain risks more clearly, or demand that clarity from others.
Studies on risks, especially those related to health, generate headlines because they are of concern to the public. A good understanding of risk is crucial for making decisions such as getting vaccinated, taking care of one's diet, choosing a contraceptive method or changing consumer habits. However, it is difficult: it is a statistical concept that is often identified with danger and provokes feelings, so its perception is subjective. This guide, accompanied by an infographic, brings together seven recommendations for risk information from the expert María del Carmen Climént.
A study published today in The Lancet claims that there are no benefits to alcohol consumption for young people between the ages of 15 and 39. However, the authors claim that in adults over the age of 40 consuming a small amount may confer some health benefits.
Communicating outbreaks of infectious diseases is not easy, especially when they affect population groups that may face discrimination. Cases of monkeypox among men who have sex with men remind us of the importance of reporting without stigma.
"The level of alcohol consumption that does not harm health is zero," says a review of dozens of studies conducted in recent years on the effect of light drinking. The 20 or so authors of the paper, and other experts, insist that "alcohol is carcinogenic from the first drink". In their view, this message should be conveyed more clearly to the public.
