Denver is grappling with major health risks due to the escalation in temperatures and heatwaves, a direct consequence of climate change. These high temperatures pose a significant menace to everyone, most notably the elderly, children, outdoor workers, individuals with preexisting health conditions, and those lacking adequate home cooling. As the climate warms, the risks associated with these rising temperatures continue to grow.
Heat Risk in Denver
Notably, the city has recorded an upward trend in heat-related illnesses, ranging from dehydration to heat stroke. The Colorado Department of Public Health and Environment has reported the highest rate of medical visits for such illnesses since 2019. This alarming rise in heat-related health issues underscores the severity of the problem.
In addition, certain low-income neighborhoods in Denver are more vulnerable to heat. These areas typically have less tree coverage and more infrastructure that retains heat, thereby intensifying the risk. In response, the city has initiated measures such as tree planting and offering rebates for heat pump installations. These efforts are aimed at reducing heat and improving living conditions in these neighborhoods.
Denver’s Office of Climate Action, Sustainability and Resiliency is taking a comprehensive approach to address the risk of rising heat. This includes hosting summits to brainstorm solutions and prioritizing the most impacted neighborhoods. By bringing together experts, community leaders, and residents, the city aims to formulate effective strategies to combat the effects of rising temperatures and extreme heat.
The summer heat in Denver is reaching unprecedented levels. The city has already set records this summer for the most 100-degree days, with temperatures hitting triple digits multiple times in July. Furthermore, several heat records have been broken, including surpassing records that have stood for over a century. According to climate model projections, these trends are likely to continue.
However, despite the record-breaking heat, the average temperature for July has remained consistent with previous years. This suggests that the summer overall was not extraordinarily hot. Nonetheless, the frequency of extreme heat events and their associated health risks highlight the urgent need for comprehensive action to address the impacts of climate change in Denver. Studies from Colorado State University indicate that climate extremes and extreme weather events like heat waves are becoming more common.
Flood and Fire Risk in Denver
In addition to heat risks, Denver faces significant flood and fire risks. Warming temperatures and earlier spring runoff can lead to severe droughts and extreme precipitation events. These changes in weather patterns affect soil moisture levels, with summer soil moisture becoming increasingly critical for maintaining healthy ecosystems. The Western Water Assessment has highlighted the importance of monitoring these changes to mitigate the impacts on both urban and rural areas.
