Our weather is getting weirder, but weird weather can do less harm when we can see it coming.ĭerek Lemoine is a professor of economics in the Eller College of Management at the University of Arizona. The frequency of extremely hot days is increasing due to climate change, making more accurate weather forecasts even more important for human health and survival. Future improvements could come from similar channels and from applying recent innovations in machine learning and artificial intelligence to weather prediction and communication. Past improvements have come from better models, observations and computers. Our results suggest investing in improved forecast accuracy would be worth the cost. About 68% of the next-day temperature forecasts now have an error of less than 1.8 degrees. Weather forecasts have gotten steadily better over the past decades. In comparison, the 2022 budget of the National Weather Service was less than $1.3 billion. The result shows that 50% more accurate forecasts are worth at least $2.1 billion per year based on the mortality benefits alone. We used federal cost-benefit estimates of how people value improvements in their chances of survival to estimate their willingness to pay for better forecasts. Here are some tips on how to stay safe and cool during hot weather. We found that on days when the forecast called for temperatures to be milder than they turned out to be - either cooler on a hot day or warmer on a cold day - people spent more time on leisure and less in home or work settings.Ĭalifornia How to stay cool and safe during California’s first heat wave of the summerĬalifornia’s first heat wave of the year could last into next week. The fact is, people do pay attention to weather forecasts and adjust their activities in response to them. Yet forecasts that overestimated the summer heat or winter cold had little impact. Summer days that were hotter than forecast and winter days that were colder than predicted had more deaths. We found similar results when the forecast was wrong on hot days with temperatures above 86 degrees Fahrenheit and on cold days with temperatures below freezing. Because weather conditions were the same, any differences in mortality could be attributed to how people’s reactions to forecasts affected their chance of dying in that weather. We then compared deaths in each county over the week following a day with accurate forecasts to deaths in the same county over the week following a day with inaccurate forecasts but the same weather. ![]()
