Wind fall trees an obstacle

Last month a mysterious orange film ("goo" in the media vernacular) washed up on the shores of a northwest Alaskan village called Kivalina. An orange powder seems an odd product for the drying of crustacean eggs, but could make perfect sense for fungi -- specifically, the rust fungi.

The outlook for blueberries in Southcentral Alaska this year is bleak, scientists say. The reason: Two species of moth have damaged berry patches, as well as native deciduous trees, from the southern Kenai Peninsula to Mat-Su.

STERLING, Alaska — Spent today tramping around the boggy depths of the Kenai National Wildlife Refuge, which is about a three-hour drive south of Anchorage. Berg The group went there to see h…

Twenty-five students in the Pribilof Island Marine Science Camp have discovered the second-known population of a new species.

CBC reporter Kaitie Fraser spotted this strange jelly-like substance in her aunt's backyard, growing on a cedar tree. In fact, her aunt said, when she first saw it, it looked like orange flowers at a distance. But when she started to approach it, it looked more like clumps of gummy bears.

Nunavut is not prepared to deal with the impacts of climate change and doesn't have a plan to deal with them, according to the latest report by Canada's auditor general.

I am sad to see the crops on my fields being just brown and yellow instead of green. All the hard work we did this spring, it's almost for nothing..." dairy farmer Filip Nilsson told Radio Sweden.

The aggressive infestation that took hold in the Matanuska-Susitna Borough north of Anchorage in 2016 has now spread north, covering hillsides in the communities outside the park with rustred dead trees and reaching into park boundaries.

The European black slug was first introduced into Alaska in the 1980s in Cordova, Slowik said. It eventually made its way to Juneau and Ketchikan, likely hitching a ride on fishing gear, and is now prevalent across Southeast. A few years ago, people started seeing the slug in Whittier and Girdwood.

The river, which starts at the Saskatchewan Glacier in the Columbia Icefields and flows through to central Saskatchewan, is usually murky brown by the time it reaches Edmonton in summer. In recent weeks, however, the water has taken on the hues of Alberta's glacial lakes, thanks to dry, hot weather combined with maintenance at a major dam.

They are brightly coloured, beautiful and hungry — tropical fish and sea urchins are thriving in southern waters warmed by climate change. But now they are devastating kelp forests already knocked around by marine heatwaves.

The birch leafminer ate its way through birches across Southcentral and Interior Alaska this summer. Hot and dry weather earlier in summer may have been optimal for them.
