What affects the tundra?
The oil, gas, and mining industries can disrupt fragile tundra habitats. Drilling wells can thaw permafrost, while heavy vehicles and pipeline construction can damage soil and prevent vegetation from returning.
How does the sun affect the tundra?
But even the sun can’t warm the tundra much. The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost, ice that never goes away in the ground, to melt, creating bogs and shallow lakes that don’t drain.
What environmental factors would cause tundra organisms to perish?

What type of climate would a tundra have?
Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts. They have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year.
How do seasons affect the tundra?
The tundra climate has two main seasons – winter and summer. … During the summer, the snow and ice may melt enough to form shallow lakes on the surface but the water cannot penetrate the still frozen soil. There is also less wind during the summer months, which also allows for plant growth.

How does the tundra contribute to a reduction of carbon dioxide on earth How is climate change affecting the tundras ability to reduce carbon dioxide?
Tundra is one of the biggest carbon dioxide sinks on Earth. … As a result of climate change, tundra soils are thawing deeper and deeper and for a longer periods of time in the upper layers of permafrost. This causes organic matter to decompose faster, releasing larger amounts of carbon dioxide into the atmosphere.
