Analyzing Accelerated Arctic Warming

A scientific model describes a self-reinforcing warming cycle involving the Earth's vast regions of frozen soil. Arrange the following events to show the correct sequence of this cycle, starting with the initial trigger.

A scientific report describes a phenomenon where rising global temperatures cause vast, permanently frozen regions of soil to thaw. This thawing process releases significant amounts of trapped gases into the atmosphere, which in turn trap more heat. How is this phenomenon best characterized in the context of climate systems?
