This seems like an unlikely place for fires. In the winter the landscape is still. But the warmer months can bring conditions that, combined with fire, can release dangerous amounts of carbon into the atmosphere And in more ways than one. What happens in the Arctic does not stay in the Arctic anymore. NASA Explorers Episode Three The Carbon Probl... Read More

Questions & Answers

Q: How does permafrost thawing affect carbon emissions in the Arctic?

Thawing permafrost in the Arctic leads to the release of significant amounts of stored carbon. As the permafrost thaws, the solid ground transforms into mud, accelerating carbon release into the atmosphere.

Q: What are the consequences of fires in high northern latitudes?

Fires in the Arctic have become more frequent, larger, and intense, which burn off the insulating layer of permafrost vegetation. This removal of insulation accelerates the release of carbon into the atmosphere.

Q: Why is understanding permafrost important in addressing climate change?

Permafrost stores twice as much carbon as currently present in the atmosphere. By comprehending the impact of permafrost thawing and carbon release, we can develop strategies to mitigate and manage climate change effectively.

Q: How did personal circumstances shape Kevin's journey as a scientist?

Experiencing his mother's illness and impending death, Kevin realized his passion for making a difference by saving the planet. He initially aimed for spaceflight but redirected his focus to Earth observations, leading him to become a scientist.

Summary & Key Takeaways

• Thawing permafrost in the Arctic causes trees, buildings, and roads to buckle and release large amounts of carbon into the atmosphere.

• Fires in high northern latitudes are increasing in size, frequency, and intensity, removing the reliable insulation layer of permafrost and releasing carbon faster.

• Understanding the impact of permafrost on carbon release is crucial in addressing climate change.
