Recent wildfires in Siberia raised major global concerns over the threat posed to permafrost

The video discusses the rapid warming in the Russian Arctic, which is causing permafrost to thaw. This thawing leads to soil erosion, revealing mammoth tusks and releasing greenhouse gases like methane and CO2. The video highlights the work of Lakita Zima and his father Sergei in raising awareness about these changes. It also explores the carbon content in permafrost and the potential for increased emissions as the permafrost continues to degrade.

What is the primary consequence of the rapid warming in the Russian Arctic?

• Increased snowfall

• Thawing of permafrost

• Decrease in wildlife

• Rise in sea levels

What have Lakita Zima and his father dedicated their lives to?

• Preserving Arctic wildlife

• Collecting mammoth tusks

• Building Arctic shelters

• Raising awareness about thawing permafrost

What has the soil erosion in the Arctic revealed?

• Ancient artifacts

• Mammoth bones

• New plant species

• Underground rivers

What is a significant component of permafrost that contributes to global warming when released?

• Nitrogen

• Oxygen

• Carbon

• Sulfur

What happens to the ice in permafrost as it thaws?
