Subsistence hunters in the Arctic have long taken to the sea ice to hunt seals, whales, and polar bears. But now, as the ice disappears and soaring temperatures alter the life cycles and abundance of their prey, a growing number of indigenous communities are facing food shortages.
Canada’s tar sands industry is in crisis as oil prices plummet, pipeline projects are killed, and new governments in Alberta and Ottawa vow less reliance on this highly polluting energy source. Is this the beginning of the end for the tar sands juggernaut?
Rapidly rising temperatures, changes in precipitation, and increased lightning strikes are leading to ever-larger wildfires in the northern forests of Alaska, Canada, and Siberia, with potentially severe ecological consequences.
As the U.S. and Russia take the first steps to drill for oil and gas in the Arctic Ocean, experts say the harsh climate, icy seas, and lack of infrastructure means a sizeable oil spill would be very difficult to clean up and could cause extensive environmental damage.
With the Keystone XL and other pipeline projects running into stiff opposition, Alberta’s tar sands industry is facing growing pressure to find ways to get its oil to market. One option under consideration would be to ship the oil via an increasingly ice-free Arctic Ocean.
Ecologist Wendy Palen was one of a group of scientists who recently called for a moratorium on new development of Alberta’s tar sands. In a Yale Environment 360 interview, she talks about why Canada and the U.S. need to reconsider the tar sands as part of a long-term energy policy.
Hydraulic fracturing is about to move into the Canadian Arctic, with companies exploring the region's rich shale oil deposits. But many indigenous people and conservationists have serious concerns about the impact of fracking in more fragile northern environments.
From the Columbia River basin in the U.S. to the Prairie Provinces of Canada, scientists and policy makers are confronting a future in which the loss of snow and ice in the Rocky Mountains could imperil water supplies for agriculture, cities and towns, and hydropower production.
The mining of Canada’s tar sands has destroyed large areas of sensitive wetlands in Alberta. Oil sands companies have vowed to reclaim this land, but little restoration has occurred so far and many scientists say it is virtually impossible to rebuild these complex ecosystems.
With some species of Arctic birds experiencing steep drops in population and their prey also undergoing marked shifts, scientists are working to understand what role climate change is playing in these unfolding ecological transformations.
The Peace-Athabasca Delta, one of the world’s largest freshwater deltas, is facing major change as rising temperatures, a prolonged drought, and water withdrawals for Alberta’s tar sands industry threaten to increasingly dry out this vast expanse of waterways and wetlands.
Environmental questions about Canada’s massive tar sands development have long centered on greenhouse gas emissions. Now there are mounting concerns about the huge volumes of water used by the oil industry and the impact on the vast Mackenzie River Basin.
China’s recent admission to the Arctic Council under observer status reflects a new reality: the world’s economic powers now regard development of natural resources and commerce in an increasingly ice-free Arctic as a top priority.
In a new paper, the world’s leading polar bear scientists say the time has come to consider drastic measures to save these iconic animals, including supplemental feeding by humans during ice-free periods and relocating more southerly populations to the High Arctic.
The rapid development of Alberta’s tar sands has spawned a new proposal for a 731-mile pipeline that would transport oil to the British Columbia coast. The project is strongly opposed by conservationists and First Nations leaders, who fear the environmental risks it would bring.
With Arctic summer sea ice rapidly disappearing, the native Inuit of Canada are encountering not only unsettling changes in their subsistence way of life, but also a growing number of outsiders who will further transform their once-isolated homeland.
Prime Minister Stephen Harper’s government has been weakening Canada’s environmental regulations and slashing funds for oversight and research — all while promoting aggressive resource development. Critics warn these unprecedented actions pose a major threat to the nation’s vast natural heritage.
With melting sea ice opening up previously inaccessible parts of the Arctic Ocean, the fishing industry sees a potential bonanza. But some scientists and government officials have begun calling for a moratorium on fishing in the region until the true state of the Arctic fishery is assessed.
Polar bears have long come ashore in Churchill, Manitoba, the self-styled ‘Polar Bear Capital of the World.’ But as summer sea ice steadily disappears in Hudson Bay, bears are being marooned on land for longer periods of time — and that is generating a lot of work for the Polar Bear Alert Team.
Canada’s Nunavut Territory is the largest undisturbed wilderness in the Northern Hemisphere. It also contains large deposits of uranium, generating intense interest from mining companies and raising concerns that a mining boom could harm the caribou at the center of Inuit life.
The development of the tar sands and other oil and gas fields in Alberta has carved up the Canadian province's boreal forest, threatening herds of woodland caribou. But rather than protect caribou habitat, officials have taken a controversial step: the large-scale killing of the wolves that prey on the caribou.
For millennia, the blanket of ice covering the Arctic Ocean protected the shore from damaging storms. But as that ice buffer disappears, increasingly powerful storm surges are eroding the coastline and sending walls of seawater inland, devastating Arctic ecosystems that support abundant wildlife.
Grizzly bears mating with polar bears. Red foxes out-competing Arctic foxes. Exotic diseases making their way into once-isolated polar realms. These are just some of the worrisome phenomena now occurring as Arctic temperatures soar and the Arctic Ocean, a once-impermeable barrier, melts.
Across the Far North, populations of caribou — an indispensable source of food and clothing for indigenous people — are in steep decline. Scientists point to rising temperatures and a resource-development boom as the prime culprits.
The massive oil spill in the Gulf of Mexico is a warning, conservationists say, of what could happen in the Arctic as melting sea ice opens the Arctic Ocean to oil and gas drilling. Many experts argue that the time has come to adopt an Arctic Treaty similar to the one that has safeguarded Antarctica for half a century.
Wildlife biologists and climate scientists overwhelmingly agree that the disappearance of Arctic sea ice will lead to a sharp drop in polar bear populations. But some skeptics remain unconvinced, and they have managed to persuade the Canadian government not to take key steps to protect the animals.
As the Arctic's sea ice melts, energy and mining companies are moving into previously inaccessible regions to tap the abundant riches that lie beneath the permafrost and the ocean floor. The potential environmental impacts are troubling.
