Tropospheric ozone - Summers of smog

The video discusses a study by the National Center for Atmospheric Research predicting a 70% increase in unhealthy summertime ozone levels by 2050 due to climate change. Ground-level ozone, formed by sunlight interacting with pollution, poses health risks. The study suggests that reducing certain pollutants can lower ozone levels despite climate change. Advanced supercomputers enabled detailed simulations of future pollution scenarios.

What is the primary cause of the increase in unhealthy summertime ozone levels by 2050?

• Harmful ground-level ozone

• Depletion of the ozone layer

• Increase in UV radiation

• Beneficial ozone in the stratosphere

How does climate change contribute to the worsening of ground-level ozone?

• By increasing temperatures and altering atmospheric conditions

• By reducing the amount of sunlight

• By decreasing pollution from cars and industries

• By increasing the beneficial ozone in the stratosphere

Which areas in the US are expected to experience unhealthy air most of the summer due to high pollution?

• Mountainous regions

• Cities with the highest pollution

• Rural areas

• Coastal regions

What can potentially reduce ozone levels despite climate change?

• Increasing the use of fossil fuels

• Decreasing the use of renewable energy

• Increasing industrial activities

• Reducing certain pollutants

What technological advancement helped scientists simulate pollution levels for hypothetical summers?

• Creation of new weather satellites

• Development of new solar panels

• Invention of electric cars

• Use of one of the fastest Atmospheric Research supercomputers
