Deep-seated change
Thawing permafrost can render railroad tracks useless, as seen in this photo from the northern Tibetan Plateau taken in the early 1960s. Because water in the soil expands when frozen and loses volume upon melting, it causes uneven movements in the ground surface. Under sustained climatic warming, the consequences of disappearing permafrost could be "very severe" for structures, Nelson said.
