Damascus in the Heat: Rising Temperatures and their Implications
The capital city of Syria, Damascus, is experiencing a significant rise in temperatures. Reports have indicated that temperatures are now ranging from 2 to 5 degrees above average. This ongoing trend could have various implications on local weather patterns, agriculture, and daily life. It is important for both residents and authorities to be aware of this situation and take necessary measures to ensure public safety, health, and well-being.
The Heat Crisis: Effects on Human Health and Ecosystems
Extreme heat is one of the leading causes of weather-related deaths globally, killing an average of more than 600 people per year in the United States alone. Heat stress occurs in humans when the body is unable to cool itself effectively. High humidity and elevated nighttime temperatures are key ingredients in causing heat-related illness and mortality. When there’s no break from the heat at night, it can cause discomfort and lead to health problems, especially for those who lack access to cooling, such as people with low incomes. The extreme heat also affects air quality. Hot and sunny days can increase the production of ground-level ozone, a harmful pollutant that can damage the respiratory system.
High temperatures can also be damaging to agriculture. Plant growth is negatively impacted by high daytime temperatures, and some crops require cool night temperatures. Heatwaves also increase the chances of livestock experiencing heat stress, especially when night-time temperatures remain high and animals are unable to cool off. Heat-stressed cattle can experience declines in milk production, slower growth, and reduced conception rates. Heatwaves can exacerbate droughts and wildfires, which can lead to negative impacts on the agriculture sector.
Threat to Energy Systems
Warmer temperatures affect many aspects of energy systems, including production, transmission, and demand. Higher summer temperatures increase electricity demand for cooling while simultaneously lowering the ability of transmission lines to carry power, possibly leading to electricity reliability issues like rolling blackouts during heatwaves. In addition, as rivers and lakes warm, their capacity for absorbing waste heat from power plants declines, reducing the thermal efficiency of power production and possibly leading to plant shutdowns.
Strategies to build resilience to extreme heat include identifying vulnerable populations and creating heat preparedness plans. Such plans may include steps like opening cooling centers during periods of extreme heat and adopting workplace heat stress standards. Other measures, such as installing cool and green roofs or cool pavement, can help reduce the urban heat island effect. Pursuing energy efficiency can also help reduce demand on the electricity grid, especially during heatwaves.
Damascus is one of the oldest continuously inhabited cities in the world. Its strategic location, natural endowments of an assured water supply and fertile land, and the intricate irrigation system developed by successive colonizers have made Damascus self-sufficient. However, the increasing heat poses a threat to this ancient city and its residents. As the temperatures continue to rise, it is crucial for the city to adapt and build resilience to protect its people, agriculture, and infrastructure from the adverse effects of extreme heat.
