"ANCHORAGE, Alaska — The group aiming to develop a giant copper and gold mine in the Bristol Bay area is vetting the scientific studies that underlay its work, turning to a Colorado-based non-profit with expertise in environmental conflict resolution.

"A team of biologists has just announced the first documented case of bird-to-bird malaria transmission in Alaska. Writing in the journal PLOS ONE, they've shown that this frequently fatal avian illness, which is normally associated with the tropics and temperate areas, may be expanding its range.

The one big exception, however, is the Chukchi Sea, where Shell is hoping to explore for oil this summer."

"Two Canadian biologists have reported sighting a handful of grizzly bears and hybrid grizzly/polar bears at unusually high latitudes in the Arctic, indicating that the interbreeding of the two bear species is becoming more common as the climate warms and grizzlies venture farther north."

"Shell is scaling back plans to drill up to five wells in Arctic waters this summer amid a series of setbacks, including stubborn sea ice still clinging to Alaska’s shores and delays in construction of an emergency oil spill containment barge."

"WHITEHORSE, Yukon Territory — In February 1942, President Franklin D. Roosevelt gave the Army Corps of Engineers an assignment: Build a road from British Columbia across the Yukon to Alaska — in eight months, before winter sets in."
