As summer temperatures rise, the frequency of extreme weather events is increasing, posing significant risks to public safety. The U.S. experiences the highest number of billion-dollar disasters from April through August each year, driven by a warming atmosphere that enhances storm systems and amplifies heat stress.
Alongside extreme weather, the prevalence of insect-borne diseases escalates during this season. The Centers for Disease Control and Prevention (CDC) projects that around 476,000 people in the U.S. will be diagnosed with Lyme disease annually, with the majority of cases occurring in late spring and summer. The emergence of mosquitoes and ticks during warmer months contributes to the spread of diseases like West Nile virus and Lyme disease, both of which have seen a rise in incidence over recent decades.
Additionally, climate change is extending the duration and intensity of summer, further exacerbating these issues. As global temperatures continue to rise, the combination of extreme heat and humidity poses serious health risks, particularly for vulnerable populations.
