Two cases of Highly Pathogenic Avian Influenza (HPAI) have been confirmed in Pocahontas and Guthrie counties in Iowa, but the U.S. Centers for Disease Control and Prevention (CDC) states that there is no public health concern.

Authorities say at least seven people have been killed after a “superfog” of smoke from south Louisiana marsh fires and dense fog caused multiple massive car crashes involving 158 vehicles.

Coastal communities in the Northwest Territories of Canada were hit by a weekend storm, causing high winds and massive waves that led residents to scramble to save boats and cabins from being washed away.

Several hundred reindeer drowned in Porsanger during their migration from summer to winter pastures, causing significant loss for the district and prompting the local government to offer crisis support to affected reindeer owners.

El Bosque, a Mexican fishing village with a population of 400 people, is being swallowed by rising sea levels, and experts predict that the entire village could be underwater within a year, leaving residents displaced and without adequate housing alternatives.

David Kuptana, an elder and full-time harvester said ice should be forming around his home on Victoria Island this time of year — but instead, temperatures have been hovering around zero and it's been raining.

Heavier rains and aging distribution networks are triggering more cases of public water supply contamination. The local utility takes water from the Esse River for processing and distribution. Because of recent heavy rains and strong runoff, it contains an unusually high level of solid matter.

Remnants of Typhoon Bolaven brought the rain from the Pacific. The typhoon has been bringing rain to the Southeast region for days. Ketchikan's one-day record is nearly nine inches, set on Oct. 11, 1977.

Samuel Roberts, 65, and Mark Elson, 51, said they were not prepared to be lost along the shore of Great Slave Lake when they headed out for a short fishing trip. But it became smoky and foggy, and the men became disoriented. The following day, when the air cleared, Roberts said they couldn't recognize anything. "We had no idea that we crossed over the Dettah side and [were] headed to the East Arm," said Elson.

Viruses have now been found in mosquitoes or in animals around the state, prompting health officials to warn Maine residents to protect against mosquito bites. The Maine Center for Disease Control and Prevention reported positive tests for eastern equine encephalitis, or EEE, in several emu flocks and multiple horses. Also, a horse tested positive for West Nile Virus in York County.

Residents of Borgarfjörður Eystri have had to boil their drinking water for two weeks due to coliform bacteria in their water sources. “This has probably come about because of soil subsidence [sinking ground] in the wet land in that area,” stated Glúmur Björnsson, a geologist at utilities contractor HEF Veitur.

Unusually heavy rains in Lapland have caused water levels to rise near flood levels, and further rises will depend on temperatures over the next few days, with climate change being a contributing factor.

There have been similar, even larger outbreaks of avian flue in seabird colonies in north Norway. In some cases, the losses were dramatic and major fractions of the colonies were wiped out. In Spitsbergen, avian flu was found for the first time in 2002, but the recent outbreak on Hopen is the largest one so far.

Melting glaciers in Iceland are contributing to an increased supply of electrical power. In the past ten years, the additional supply has amounted to one medium-sized power plant.

A humpback whale calf found dead near Juneau, Alaska was killed by a large boat, according to biologists who found deep lacerations on the calf's body and pectoral fin likely caused by a propeller, highlighting the risks of vessel strikes and the need for reduced speeds and increased distance between boats and whales.

In Dillingham, Alaska, 19 cases of avian flu have been identified in common murres, with the virus still present in wild birds and genetic testing being conducted to determine if it is a new strain or a strain circulating in North America.

Finnish authorities are investigating a gas leak outside of Finland, suspected to be caused by external activity, with both the security police and defense forces involved in the case.

Scientists from the University of Alaska Fairbanks have observed an increase in chum salmon spawning in North Slope rivers, potentially indicating a shift in their population and a signal of climate change. Elizabeth Lindley, a Ph.D. student working on the project, says that while evidence of spawning in a new region may be a positive for salmon, the impact on important subsistence resources including Arctic char and Dolly Varden is uncertain.

The Lower Elwha Klallam Tribe catches coho salmon on the free-flowing Elwha River for the first time in over a century since the removal of dams, marking a historic moment for the tribe and the river's recovery.
