What makes your think that we do not understand the chemistry here?
Where do we start the “x is caused by y”? The way it actually happened? Then melting permafrost is indeed the first step.
If you want to go by how we ended up perceiving it, then you need to start, for example, at how the brown color came to be. Then where that came from. Then what caused it to be made. Etc.
