"Heatwaves and Droughts: Getting Worse with Climate Change"

In the past decade, heatwaves that used to happen once every 10 years have now occurred 2.8 times in 10 years and are 2.2 degrees hotter on average. At the current global warming rate of 3.6 degrees, these heatwaves could strike 5.6 times over the same period and be 4.68 degrees hotter. This doesn't account for extreme heatwaves which can be hundreds of times more likely due to climate change. For instance, a 2012 heatwave in North America was at least four times more likely than it would have been pre-industrially. Cities like Chicago are particularly vulnerable as urban heat island effects amplify temperatures, making extreme weather dangerous for residents.

While droughts are complex and vary greatly by region, they're becoming more common and severe in areas like the western United States. As the atmosphere warms, evaporation increases, leading to intense but short rainfall events that saturate soil and contribute to flooding instead of alleviating dry conditions. The Midwest may not see a significant increase yet, but prolonged dry periods are becoming more common. Extreme weather doesn't respect borders; wildfires in Canada can affect air quality in the U.S. These events underscore the importance of climate resilience and mitigation efforts to prepare for future disasters. Fossil fuel burning is identified as the primary cause, and if unchecked, these events will worsen over time.
