VOICED : Thawing permafrost climate changes ticking time bomb

The video discusses the rapid melting of permafrost in the northern hemisphere, particularly in the Great Canadian North, due to global warming. It highlights the environmental impact, such as the formation of ponds and the release of greenhouse gases like carbon dioxide and methane. Researchers are actively monitoring these changes to understand their implications. The video emphasizes the potential future risks and the need to address global warming to mitigate these effects.

What is the primary cause of the rapid melting of permafrost in the northern hemisphere?

• Increased rainfall

• Global warming

• Deforestation

• Volcanic activity

What tools do Flora and his team use to study the permafrost?

• Cameras

• Sensors

• Satellites

• Drones

What gases are released due to the melting of permafrost?

• Oxygen and nitrogen

• Helium and argon

• Carbon dioxide and methane

• Hydrogen and neon

What is the potential consequence if all the carbon in permafrost is released into the atmosphere?

• It would decrease the concentration of CO2 in the atmosphere

• It would triple the concentration of CO2 in the atmosphere

• It would have no significant impact

• It would double the concentration of CO2 in the atmosphere

What is the only way to stop the vicious cycle of permafrost thawing and global warming?

• Encourage deforestation

• Stop global warming

• Increase industrial activity

• Promote urbanization
