Flood in São Paulo; climate change increases probability of extreme rains

An international survey carried out with young people from ten countries shows that Brazilians between 16 and 25 years of age are the ones who most hesitate to have children because of climate change.

Almost half (48%) of Brazilians interviewed said that climate change makes them hesitant about having children. This proportion was well above the world average (39%) and was the highest percentage recorded in the ten countries surveyed – Australia, United States, United Kingdom, India, Nigeria, Philippines, Finland, Portugal, Brazil and France.

In the UK, for example, the percentage of young people who are hesitant about having children because of climate change is 38%. In the US it is 36% and in Australia 42%.

The study, which listened to 10,000 people between 16 and 25 years of age and asked questions about the level of anxiety among young people about climate change, was carried out by researchers from several institutions – such as the Center for Innovation in Global Health at the Faculty of Medicine of Stanford University and the University of Helsinki – and was funded by the Avaaz platform.
