The animal was spotted Thursday about seven or eight kilometres away from the sand pits.

It’s not clear whether the unrest will lead to an eruption at Tanaga Volcano, which is located on an uninhabited island about 65 miles from Adak.

The peer-reviewed research published this week in the Public Library of Science suggests that 99% of the orcas studied had photographic evidence of skin lesions. Researchers evaluated photos from nearly 20,000 orca sightings from 2004 to 2016, finding that lesions — often gray patches and gray targets on the orcas' skin — generally became more prevalent over time.

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.

“Significant ash emissions” were possible for several hours following the unrest on Shishaldin Volcano in the Aleutians, according to the Alaska Volcano Observatory.

Havana mansions in Cuba are crumbling due to neglect, bad weather, and economic crisis, leaving residents living in fear of collapse and struggling to receive help from authorities. Cuba’s housing crisis is one of the most pressing challenges facing the island, where a humid climate, the passage of hurricanes and other storms, poor maintenance and a low completion rate of new ones are usually among the top complaints of Cubans.

Every year, Aklak Air switches to flying a Twin Otter to Sachs Harbour in the spring and fall because the gravel runway is too soft for other aircraft. The switch usually lasts for a few days, up to a week, but this fall's warm weather made it necessary for longer and its effects were felt beyond the runway.

Halobacteria thrive in bodies of water with high levels of salt. The salinity inside the Kealia Pond outlet area is currently greater than 70 parts per thousand, twice the salinity of seawater. Maui's drought is likely contributing to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn't happened in a long time.

"I've worked forecast in this area for 33 years. It's very rare. I don't remember any community in B.C. having that much damage from a tornado in my career or in the Peace," said meteorologist Doug Lundquist. 

Finnish Meteorological Institute researchers said the reduction in snow cover was caused by global climate change and is likely to accelerate.

"The damage happened at about 2 a.m. Monday morning when heavy rain caused the landslide and damaged about 2,000 feet of lines."

The weather is a result of a low-pressure system from the East Coast heading northward from Labrador, fueled by the moisture in the Atlantic Ocean.

The southern resident killer whales who returned to their traditional summer feeding grounds in the Salish Sea on Tuesday and Wednesday after a long absence have apparently left again, and although most of the members of J-, K- and L-Pods appeared to be healthy, at least one may be close to starvation.

Seven polar bears, including a wounded mother bear with two cubs, were scared away by rescuers after they got dangerously close to reindeer herders at several locations on the Yamal peninsula. There are concern over rising numbers of the Arctic’s largest predators leaving their natural habitat and coming closer to humans.

Crops across much of Saskatchewan are scorched, stunted and thin as they wither under the unrelenting heat wave blanketing Saskatchewan, according to the province's latest crop report.

According to preliminary data, more than seven thousand walruses were recorded, which is two times as many as last year. This was also when the largest walrus habitat in the history of Arctic exploration was found on the northernmost island of the Franz Josef Land archipelago, the Eva-Liv island.

Last summer while scoping for marine invasive species we found the invasive colonial tunicate, Didemnum vexillum also know as marine vomit.

Murang’a County Director of Meteorology Paul Murage stated that the ongoing short rains are below average and expressed worries that the Ndakaini dam may not achieve full capacity by the end of the season. Following the low water volume residents in the city will experience water rationing in areas that are served by the dam as early as next year.

High winds at the Muklung tower blew the antenna pointing at Levelock out of alignment. It was too windy for the technicians to fly back to finish repairs at the Muklung site on Thursday. On Friday, the cooperative said they were able to reach the site, but the winds were still too strong for them to climb the tower to fix the antenna.

Bulldozer crews have cleared trails and fields for the bison in hopes of reducing the danger of collisions and damaged fields. There's a layer of ice up to two inches thick within the snowpack that has further complicated foraging.
