The environmental problems with tundral regions and global warming are varied and worrying. The main concern in relation to global warming is that, as the underlying permafrost melts, methane (a greenhouse gase) will be released from the tundra, contributing further to the vicious circle.

This article here, prepared by the US Environmental Protection Agency, details some of the environmental effects that global warming are having/will have in Alaska, a region of mostly pristine ecosystems including tundral systems.
