NASA | The Future of Fires

The video discusses the impact of fires on Earth, highlighting images from space that show the extent of damage. It explores how climate change is increasing fire frequency, especially in areas not prone to burning. The consequences include risks to homes, federal spending, and food supply. The video also examines mitigation strategies and scenarios, emphasizing the need to reduce greenhouse gas emissions to limit temperature rise and fire occurrences.

What are the main gases released into the atmosphere due to fires?

• Sulfur Dioxide, Nitrogen Dioxide, and Ozone

• Hydrogen, Argon, and Neon

• Carbon Monoxide, Methane, and Carbon Dioxide

• Oxygen, Nitrogen, and Helium

How is climate change expected to affect fire frequency in the United States?

• It will increase fire frequency in areas not currently prone to fires.

• It will only affect fire frequency in coastal areas.

• It will have no impact on fire frequency.

• It will decrease fire frequency in all regions.

Which regions are expected to see an increase in fire frequency by the end of the 21st century?

• Deserts and coastal areas

• Great Plains and Upper Midwest

• Urban areas

• Tropical rainforests

What is the expected temperature rise under a low carbon scenario?

• 8 degrees

• 6 degrees

• 4.5 degrees

• 2 degrees

What is the consequence of higher temperatures on fire frequency?

• Fewer fires in more places

• More fires in fewer places

• More fires in more places

• No change in fire frequency
