El cambio climático Y su salud

The report finds that the US Midwest has experienced a significant increase in dangerously hot and humid summer days since the 1940s and 1950s. This trend increases the risk of heat-related illnesses and deaths, particularly for vulnerable populations such as the elderly, children, and urban residents. The analysis, covering 10 cities across eight states, indicates that rising nighttime temperatures and more frequent heat waves exacerbate health risks. Projections suggest that without significant carbon emission reductions, the region will face a substantial increase in days exceeding 90°F and 100°F by the end of the century.

• Extreme heat is the leading cause of weather-related deaths in the United States, causing more annual fatalities than floods, lightning, tornadoes, and hurricanes combined. Between 1999 and 2003, excessive heat exposure resulted in approximately 3,442 deaths of US residents.
• Over the last 60 years, the US Midwest has seen an increase in the frequency of dangerously hot and humid summer days, as well as hotter dry days. Conversely, there has been a decrease in cool, dry days that typically provide relief from summer heat.
• High temperatures and humidity increase the risk of hyperthermia and dehydration, and can worsen existing medical conditions such as heart disease, kidney disease, respiratory illnesses, and diabetes. Vulnerable groups include children, the elderly, urban residents, agricultural workers, and those with limited mobility or health issues.
• The lack of nighttime cooling is a significant health risk, as higher nighttime temperatures and humidity prevent the body from recovering from daytime heat, increasing the likelihood of heat-related complications.
• Future projections indicate that if current carbon emission trends continue, the US Midwest will likely experience a sharp increase in days over 90°F and 100°F by the end of the century. For example, in St. Louis, days over 100°F are projected to rise from fewer than 3 per year (1961–1990) to 43 per year (2070–2099) under a high-emissions scenario.
