Climate Change is Making Your Weather Worse - and Now Forecasts Will Tell You By How Much

Thanks to advances in weather simulation, forecasts of heatwaves and hurricanes could soon come with information about the extent to which they were fuelled by climate change.

This new technology, which scientists and policymakers say could help people prepare for and respond to extreme weather events, could also help shift the conversation around climate change from a distant threat to a pressing, tangible reality.

For decades, scientists have struggled to connect the dots between climate change and specific weather events, from intense hurricanes and droughts to heatwaves and wildfires. But advances in computer modeling and data analysis have made it possible to quantify the role that climate change plays in these events.

This information could be used in a variety of ways, including to inform emergency preparedness and response, to guide policy and decision-making, and to raise public awareness about the impacts of climate change. For example, a forecast might say that a heatwave is expected to be 20% more severe than it would have been without climate change, or that a hurricane is likely to produce 50% more rainfall than it would have in the past.

This kind of information could also help to build trust and credibility in climate science, which is critical for building public support for action to address climate change. When people can see the concrete, tangible impacts of climate change in their daily lives, they are more likely to take it seriously and demand action.

Of course, there are still many challenges to overcome before this kind of information becomes a routine part of weather forecasting. For one thing, there is still a lot of uncertainty and variability in climate modeling, which can make it difficult to produce precise, reliable estimates of the role of climate change in specific weather events.

In addition, there are also questions about how to communicate this kind of information in a way that is clear, concise, and actionable for the public. For example, what does it mean to say that a heatwave is 20% more severe than it would have been without climate change? And how can people use that information to protect themselves and their communities?

Despite these challenges, many experts say that this kind of information is long overdue and has the potential to make a significant difference in how we prepare for and respond to extreme weather events. As the impacts of climate change continue to mount, it is becoming increasingly clear that we need to do more to prepare, respond, and adapt - and that this kind of information is a critical tool in that effort.
