No you don't, when permafrost melts it causes ground to move. It is really bad for everything build on or in it. Something like houses sinking and falling apart. In some cases it cause big holes in the ground and they got even bigger over time.

Most of Siberia does not have permafrost, though.

Because permafrost melting is the only negative consequences of climate change. There are no forest fires, no problems with insect due to milder winters, etc.
