The National Meteorological Service (SMN) warns that Argentina may experience intense heatwaves this upcoming summer, particularly in December, January, and February. Forecast maps highlight a worrying trend, indicating that the heat could reach more extreme levels than we’ve seen in the past.
Understanding Heatwaves
A heatwave isn’t just hot weather; it’s when temperatures stay dangerously high for three days or more. These critical thresholds differ across regions. For example, in Santa Fe, the maximum is 34.6 °C, while Buenos Aires has a threshold of 33 °C. Historical data shows a concerning increase in mortality during heatwaves, with the longest one recorded in December 2013 leading to a shocking 43% rise in deaths in Buenos Aires.
A Rising Trend
Heatwaves in Argentina have become more frequent since 1960, largely due to climate change. Matilde Rusticucci, a researcher at CONICET, notes that 19 of the last 20 summers have seen at least one heatwave. Shockingly, extreme heat days in Mendoza have tripled over the past decade compared to the previous ten years. Between 2005 and 2019, the risk of death during heatwaves in major cities increased by 8% to 25%.
Health Implications
Extreme heat poses serious health risks. The World Meteorological Organization labels it as the deadliest climate phenomenon, causing over 546,000 deaths annually. Vulnerable groups like children, the elderly, and those with chronic illnesses face higher risks. The impacts can be overlooked too—issues like male infertility and malnutrition in children also arise from extreme heat.
Moreover, heatwaves disrupt crucial services like energy and water supply and can hinder work performance.
Early Warnings and Community Action
In response to rising temperatures, the SMN has introduced an early warning system for heatwaves. Alerts are color-coded:
- Yellow: caution for the general public; moderate risk for vulnerable groups.
- Orange: heightened risk, especially for sensitive individuals.
- Red: serious danger, even for the healthy.
Cities across Argentina have been proactive. The “Heatwaves and the Health of the Elderly” program works in urban areas like Rosario and Córdoba. In Rosario, public drinking fountains and cooling centers are mapped for easy access.
Staying Safe in the Heat
Experts recommend simple yet crucial steps to stay safe during a heatwave:
- Keep homes cool; ventilate when possible.
- Wear light clothing and use sunscreen.
- Stay hydrated and never leave people or pets in cars.
- Connect with neighbors, especially elderly residents who may need help.
Be aware of warning signs:
- Mild: rashes and cramps.
- Moderate: headaches and dizziness.
- Severe: high body temperature and confusion.
Heatwaves, often seen as a silent threat, are exacerbated by climate change. Argentina faces challenges in protecting its vulnerable populations, adapting its cities, and raising awareness about this pressing issue. As we navigate these extreme conditions, staying informed and prepared is more important than ever.
