VOICED : Thawing permafrost climate changes ticking time bomb

The video discusses the rapid melting of permafrost in the Great Canadian North, driven by global warming. Researchers, led by a French team, are studying the environmental impact, including the formation of ponds and the release of greenhouse gases like carbon dioxide and methane. The potential for permafrost to significantly contribute to global warming is highlighted, with concerns about the vast amounts of carbon it contains. The video emphasizes the need for urgent action to mitigate global warming and prevent further permafrost thawing.

What is the primary cause of the rapid melting of permafrost in the Great Canadian North?

• Increased rainfall

• Volcanic activity

• Global warming

• Deforestation

What is one of the most visible signs of permafrost melting?

• Creation of ponds

• Increase in snowfall

• Formation of glaciers

• Emergence of new forests

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

• Sensors

• Microscopes

• Satellites

• Drones

Which gases are released due to the melting of permafrost?

• Hydrogen and neon

• Carbon dioxide and methane

• Oxygen and nitrogen

• Helium and argon

What is the potential impact of all carbon in permafrost turning into CO2?

• It would double the CO2 concentration

• It would reduce the CO2 concentration

• It would have no effect

• It would triple the CO2 concentration
