Temperature is a defining characteristic of biomes, with each biome having a characteristic temperature range. The biome with the lowest average yearly temperature is the tundra biome. This biome is characterized by cold, long winters and short, cool summers. Because of its high latitude, the tundra biome receives less direct sunlight than other biomes, which contributes to its low temperatures. The average yearly temperature in the tundra biome is below freezing, and the ground is permanently frozen (permafrost). The tundra biome is located in the northernmost regions of the planet, and is home to a variety of adapted plant and animal life.

Feedback Loops in Climate Change: The Permafrost’s Secret
Imagine your freezer is full of frozen peas. Now, let’s say you leave the door open for a while. What happens? Those peas start warming up and releasing water vapor, right?
Well, the same thing happens on a much larger scale with permafrost. Permafrost is ground that stays frozen all year round, but as the climate warms, it’s starting to melt. And when it melts, it releases a whole lot of water vapor and carbon dioxide—two powerful greenhouse gases.
Think of it like this: melting permafrost is like a runaway train. It releases gases that warm the planet, which in turn melts more permafrost, which releases even more gases. It’s a vicious cycle known as a positive feedback loop. And it’s making climate change worse.
The worst part is, these gases stay in the atmosphere for a long time. They can trap heat for centuries, continuing to warm the planet and melt even more permafrost. It’s like a never-ending game of freeze-thaw that’s wreaking havoc on our planet.
But here’s the good news: we can still stop the runaway train. By taking action to reduce greenhouse gas emissions, we can slow down the melting of permafrost and help prevent the worst impacts of climate change for future generations.

Deep beneath the icy surface of polar regions lies a vast layer of frozen soil called permafrost. For millennia, this frozen ground has trapped ancient organic matter, like a perfectly preserved time capsule. But as climate change thaws these icy depths, a sinister secret is being revealed.
The Greenhouse Gas Genie
As permafrost melts, it releases locked-away greenhouse gases into the atmosphere. These gases, primarily carbon dioxide and methane, are like unwanted party guests that contribute to our warming planet.
A Vicious Cycle
The release of these greenhouse gases creates a vicious cycle known as a positive feedback loop. As temperatures rise due to the increased greenhouse gases, permafrost melts even faster, releasing even more emissions. It’s like an unstoppable domino effect, leading to an acceleration of climate change.
Thawing Tundra and Troubled Ice
The thawing of permafrost has far-reaching consequences. It destabilizes the tundra landscape, causing it to sink and become soggy. This not only affects plant life but also disrupts the homes of wildlife that rely on this fragile ecosystem.
Moreover, as permafrost melts, it releases water, which can flow into rivers and oceans. This runoff can destabilize coastal areas and contribute to sea level rise, another devastating impact of climate change.
A Call to Action
Preserving permafrost and mitigating climate change is crucial for the health of our planet and the well-being of future generations. By reducing our carbon footprint and investing in renewable energy, we can help slow down the melting of permafrost and minimize its contribution to greenhouse gas emissions.
