Warmer conditions in the tundra increase decomposition rates enough to release carbon from stored soil organic matter, which produces a net flow of carbon to the atmosphere, which could lead to more warming.

A fire generates more heat, which increases combustion, which would cause more fire.

Warmer and drier climatic conditions lead to more fires, which in turn release more CO2

Warmer conditions lead to increased photosynthetic rates and hence an increase in uptake of CO2, which could decrease the temperature.
