How a Storm Triggered a City-Wide Asthma Attack

In November 2016, Melbourne experienced a severe thunderstorm asthma event, causing thousands to struggle to breathe and resulting in nine deaths. Thunderstorm asthma occurs when storms concentrate pollen and allergens, triggering asthma attacks. This phenomenon is rare but may become more frequent with climate change. People with hay fever or pollen allergies are at higher risk, and emergency services may be overwhelmed during such events. The video emphasizes the importance of being prepared, especially during high pollen counts.

What was the main cause of the asthma outbreak in Melbourne in 2016?

• A viral infection

• A chemical spill

• A thunderstorm

• A heatwave

What is the best scientific explanation for thunderstorm asthma?

• Storms concentrate pollen and allergens, making them more inhalable

• Storms decrease oxygen levels in the air

• Storms cause a drop in temperature, leading to respiratory issues

• Storms increase air pressure, affecting breathing

How do pollen grains become more dangerous during a storm?

• They burst open, releasing tiny granules

• They become larger and more visible

• They lose their allergenic properties

• They dissolve in the rain

Why might thunderstorm asthma events become more frequent in the future?

• Increased urbanization

• More frequent and severe storms due to climate change

• Improved pollen tracking technology
