Warming to hit "roads, pipelines" in Canada north

OTTAWA (Reuters) – Roads, buildings and pipelines in Canada’s north are at risk from global warming and the government must do more to protect infrastructure in the remote frozen region, an official panel said Thursday.

The National Round Table on the Environment and the Economy (NRTEE) said the permafrost layer had begun to melt, a development that can have disastrous consequences.

“Melting permafrost is undermining building foundations and threatens roads, pipelines and communications infrastructure,’ it said in a report, also citing the potential danger to energy systems, waste disposal sites and ponds containing toxic tailings from mines.

…In particular, the report said, communications and energy transmission towers were becoming increasingly susceptible to the risk of failure.

The changes in permafrost, which include sudden shifts in the ground, will make pipeline construction more complicated.

This could have implications for the planned C$16.2 billion 1,220 km (760 mile) Mackenzie Valley pipeline to ship gas from the Arctic to the western province of Alberta.
