ANSWER: ?
A successful answer will include at least three of the following.
- In warm summer months, upper layers of permafrost will thaw naturally.
- Climate change is increasing the extent and duration of this summer warming beyond what is expected in the affected regions.
- Large areas of water in lakes and rivers can heat the ground, causing thaw in nearby areas.
