The number of boil order advisories issued by Swedish municipalities have more than double this year compared to 2018, Swedish Radio reports.

A storm system during the last week of November brought high winds and seas to Newtok and other western Alaska communities.

Palsmyr is threatened by climate change. At Ferdesmyra in Finnmark, the characteristic ice-filled pals that protrude from the terrain will be gone in a few years.

Blooms are often associated with low dissolved oxygen events and warm ocean water temperatures and weather changes – all of which we are, or have been, experiencing," said Kiemele. Farm owner Cermaq says it has deployed fish protection countermeasures that have already caused conditions to improve.

After a decade of heavy erosion, a lake in the Bristol Bay village of Port Heiden finally breached, sending water gushing into the bay.

The ice may look solid, but emergency officials are warning Yukoners to be wary. M.A. Chartrand learned that the hard way last week.

Danny Foster and Mike Hawley of Kivalina were ice fishing outside of town when they came upon something they’d never seen before. Incidentally, similar ice balls or ice eggs were reported on an ocean beach in Finland on the same day.

Mergansers (Mergus merganser) are not common visitors to Cheney Lake, but a flock of about a dozen showed up in early November.

Gradual sea ice reduction and reconfiguration of the coast, have increased the rate of erosion near Port Heiden over the course of several decades. Draining of Goldfish Lake brings memories, loss of community landmark, and many emotions.

Low water on the Noatak River may be the reason behind changes in the water quality in community wells. The water quality began to change in the plant as measured (eventually) by the need for twice as much chlorine and Naclo polymer in order to get an acceptable residual of chlorine. The change indicates that the well recharge had been depleted and the that wells began operating on stored water in the aquifer. This water would have been older, likely anaerobic and higher in organics and in inorganics such as iron and manganese.

Nils Thomas discovered "sinkhole" in the middle of Finnmarksvidda. Scientists have long warned against this, and now it happened.

New aerial footage appears to show thousands of dead fish at Lake Pamamaroo in the Menindee Lakes System, near Broken Hill, nine months after a mass fish kill event on the nearby banks of the Darling River.

Nick Page shared the following observation of a young beaver north of Courtenay on Vancouver Island. There are not many beaver observations on Vancouver Island, and most are very recent, especially in this part of Vancouver Island. The closest iNaturalist observation is linked here.

The road through Svínadalur, near Súlá river in Leirársveit, broke apart this morning, trapping three tourists who could not get their car out again.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

Despite recent rain, groundwater levels remain at near-record lows. Markku Rantti, head of the local village association, says some wells in the area only have about 20 cm of water at the bottom.

Usually one of the most full flowing in Russia, the river tends to drop the level twice a year - but not by a catastrophic 2-2.5 meters as this year.
