Warming to hit "roads, pipelines" in Canada north
By David Ljunggren
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.
Temperatures in the north -- which includes the Arctic -- are rising much faster than elsewhere in the world, and this comes at a time of increasing interest in the area's vast mineral and energy reserves.
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.
"The risk to infrastructure systems will only intensify as the climate continues to warm."
The panel called for better building codes to help protect against the effects of climate change, better disaster planning and a change in insurance policies to encourage modifications to take into account the risks of warming.
The NRTEE -- which Ottawa set up in 1988 to provide it with information and advice on environmental issues -- also cited the risks posed by coastal erosion, storm surges, wildfires, blizzards and changing wind and snowstorm patterns.
The faster rate of warming is shortening the life of ice roads that supply massive mines like the diamond operation at Diavik in the Northwest Territories. Diavik is 60 percent owned by mining company Rio Tinto. Continued...
