It's influence on Human Activity

Transportation and infrastructure impacts

There is a substantial presence of permafrost thaw and disruptions to freeze-thaw cycles. This causes damage to the transportation infrastructure including railroads, airstrips, and highways. It leads to the uneven sinking of the ground that responds to permafrost thaw that damages the transport systems thus disrupting the movement of goods and people.9 Integrated Resource and Environmental Management: The Human Dimension, 2005)

Permafrost

Eighty percent of Alaskas surface lies above permafrost. Permafrost remains frozen for long. As the permafrost thaws, ice that results from the melting permafrost that causes the soil to sink, this affect the entire surrounding thus making it impossible for any economic activity to thrive.

Ecosystems

The adverse changes in climate in lakes, plant composition, ponds, and wetlands, it results in changes in lake sizes, some shrinking. This adversely affects the ecosystem that harbors in the waters. Lakes get smaller through evaporation that is caused by warmer temperatures that melt the permafrost.
