Climate scientists have been worried about climate change . In 1988, the was founded by the United Nations. It has been bringing together the world’s top climate scientists, to provide governments worldwide with scientific information about climate change and potential solutions.
At first, warnings about climate change did not seem to have much effect. The showed that few people around the world worried about climate change. At the time, climate change seemed to be an uncertain and distant threat. If it were to happen, it would be at some point in the far away future.
But global public opinion has shifted. The showed that over two-thirds of people around the world saw climate change as a threat. A similar level of concern was seen in the World Risk Polls of 2021 and 2023.
The shows that climate concerns are more likely among people who worry about extreme weather. Around the world, records are being set for , , . Climate change is no longer an uncertain or distant threat. And people are noticing.
But there are two drawbacks to these findings, limiting climate action. And both have implications for climate communications.
The first drawback: not everyone around the world draws the link between extreme weather and climate change. The show that climate change concerns are relatively low in some regions of Africa and Asia. This may seem odd, because these regions are being hit hard by climate change. into the Poll data found that people in these regions do worry the most about extreme weather. Interviews with South African farmers have found that they are very aware of the weather changing – but may be . It doesn’t help that climate communications use such as “mitigation” and “adaptation.”
The solution: climate communications should be easy to understand, and use concrete examples of weather changes that are expected due to climate change. My team at the University of Southern California has been working with the and the IPCC to find ways to talk about climate change in . We have written a for people who want to learn more about climate change without the buzz words. We also helped to .
The second drawback: taking action is especially important in , which contribute the most to climate change. The World Risk Poll shows that people in high-income countries tend to be the most worried about climate change. But not everyone who is worried about climate change is or willing to support policy change. One reason is that about climate change – even though the World Risk Poll shows that is not true. Another reason is that many people who are worried about climate change . Yet another reason people hesitate to act is that they believe , because contribute the most to climate change.
The solution: people are more likely to act , so sharing the is an important step towards helping people see that most others are worried about climate change. The World Risk Poll findings may also help to make policy makers more aware of shifting public opinions. Showing people what actions they can take is another important step. We therefore created .
Dr. Sarah Jenkins and Dr. Andrea Taylor discuss the integration of the Poll with data on vulnerabilities, governance, and long-term climate projections to identify predictors of disaster risk perception and preparedness, and develop early warning and risk communication strategies.
Experts discuss the factors that make some workers more vulnerable than others to violence and harassment.
Dr. Joel Gill and Dr. Faith Taylor discuss how World Risk Poll data will be used to understand contributing factors to existing high levels of household preparedness in the face of natural hazards.
