Thanks for that article on Arctic foxes. There are so many things in this world that are not dreamed of by my understanding. The world is full of marvellous things waiting for our senses to get sharper.

The total energy of forest fires in the Arctic in the past month is equal to a 200-gigawatt coal-fired power station, which emitted 50 million tons of carbon dioxide per month.

Under the category of amazing animal feats, a radio collared  arctic fox left Svalbard on March 26th, heading for Ellesmere, and arrived on June 10. It  detoured north around open water, crossed the Greenland sea, then took a look at the Greenland ice cap in winter, because, you know, bored, picked its way across the Nares- after the arch had collapsed and arrived at Ellesmere on June 10th!


What an amazing journey !

You say after the arch collapsed Sebastian, however the arch was still intact up to the very end of June last year. The same route could hardly have been chosen this year because we had no arch in the Kane Basin and would have been very tricky !

Here's the timelapse:

Surge in Sick, Hungry Sea Lions Off California Coast
https://phys.org/news/2019-07-surge-sick-hungry-sea-lions.html

A rise in the number of ailing and malnourished sea lions along the California coastline has marine experts somewhat puzzled, KNTV reports.

Some of the adult California sea lions may be suffering from domoic acid poisoning, related to toxic algae blooms in the ocean, according to the station. But experts aren't sure why they're also seeing more malnourished pups.

"Whether there is some underlying condition, we haven't been able to determine," Frankfurter said, KNTV reported. It may be related to the domoic acid poisoning cases in adults.

The upswing follows a similar surge in sea lion strandings in spring 2018 as well as a rise in California gray whale deaths in early 2019, KRON reported.

"We're seeing a lot of different animals being impacted from the gray whales that are coming in thin to the issues that we are seeing with Guadalupe animals and the sea lions up and down the coast," Frankfurter said, according to the station. "It's definitely a sign of the ocean overall. All of it might (connect) to climate change, relating to warming oceans."

More on the dead gray whales:

3 more gray whale carcasses found in Alaska amid spike in deaths along West Coast

https://www.adn.com/alaska-news/wildlife/2019/06/20/3-more-gray-whale-carcasses-found-in-alaska-amid-spike-in-deaths-along-west-coast/

Three more gray whales were found dead along the coasts of Alaska this week as scientists continue to investigate why so many of the marine mammals are dying as they migrate up the West Coast.

So far this year, 167 dead gray whales have been found dead from Mexico to Alaska, according to the National Oceanic and Atmospheric Administration. The number of the carcasses found on U.S. shores, 81, is the most since 2000.

Many of the dead whales were skinny, NOAA said. Some scientists think it’s likely the whales didn’t get enough to eat last summer in the Bering and Chukchi seas.

By Thursday, the tally of dead gray whales in Alaska had climbed to 10. Normally by this time of year, just three or four carcasses are reported, according to NOAA data from 2016 to 2018.

And more...

Alaska up to 22 dead gray whales this season with 7 reported over holiday weekend

https://www.ktuu.com/content/news/Alaska-up-to-22-dead-gray-whales-7-reported-holiday-weekend-512502861.html

The state of Alaska is up to 22 confirmed gray whale deaths this season, according to NOAA spokesperson Julie Speegle. Seven additional sightings were confirmed over the long holiday weekend, Speegle said, with one necropsy having been completed.

As of June 27, the site reported 14 Alaska whales, and 85 total for the U.S. The total for the U.S., Canada and Mexico this season was reported at 171 by that date.

*****

If my math is correct, then these additional dead whales would bring the total to at least 179, not counting any whales that may have been found in Mexico, contiguous U.S. or Canada since June 27th.

The total population is estimated 26k?

Yes, so not a crisis at this point (though of course the number of confirmed dead are only a fraction of the total deaths, since not all whales end up on shore).

But if this is related to lack of ice and warming of the Bering and Chukchi seas last year, then we will likely see an even higher number of mortalities next year...

The 179 are 0,69% of the population.

Are those all returning or do they include reports from the start of the season migrating south?

I will dig through this thread a bit to see if i can find some more numbers for the other areas.

Also note that the indigenous peoples of the Arctic (the Chukchi and the Eskimos) are allowed to kill several hundred gray whales every year.

Whales, like elephants, are prime candidates for extinction because of their size. Like once dinosaurs that could not compete with smaller mammals.

And they say that with warming a tropical paradise will come on the entire planet - a repeat of the era of dinosaurs. And in fact, the planet turns into a lifeless wasteland.

Taken from reply 240:

"Gray whales spend the summer in the northern Bering and Chukchi Seas, where they consume nearly a year’s worth of nourishment so they can migrate south to Mexico for the winter. Sea ice has been at or near record lows off Alaska, with rising temperatures likely impacting the population of amphipods crustaceans that are the whales’ primary source of food, according to NOAA.

The emaciated whales, now migrating north, are likely showing the impact of poor feeding last summer, according to officials."

The data just says mortalities from 2019. Most of them would be from the migration northwards.

If there are a number of whales already weak now arriving in the Bering and Chukchi, and if warming waters effecting availability of food really is the main factor, then I am guessing there will be moralities on the trip south this year as well as the trip north next year.

https://www.fisheries.noaa.gov/national/marine-life-distress/2019-gray-whale-unusual-mortality-event-along-west-coast

Gray Whale Strandings (as of June 27, 2019)

U.S. State       2019
Alaska       14
Washington    29
Oregon       5
California       37
Total               85
 
Country   2019
Canada     8
U.S.           85
Mexico   78
Total         171

I think this is the breakdown? So that would include the whole route.

Tiger, Rhinos Flee to Higher Ground in India's Flood-Hit Assam
https://phys.org/news/2019-07-tiger-rhinos-higher-ground-india.html



... Wild buffalos running in floodwaters, exhausted rhinos resting on patches of land and elephants crossing a road were some of the unusual sights as World Heritage-listed Kaziranga National Park rangers raced to reach animals struggling in the waters.

The UNESCO-recognised Kaziranga is home to two-thirds of the world's remaining one-horned rhinos and several have been spotted basking in the sun on a patches of high ground surrounded by water.

More than 50 wild animals have died so far, including some in traffic accidents, as they tried to cross a busy highway outside the park and reach the nearby Karbi hills, local media reported.

... The floods, which are in their second week, have so far killed at least 27 people in Assam, sweeping away houses and boats. Across South Asia, including Nepal, Bangladesh and Pakistan, the death toll has risen above 300 with millions of residents affected and hundreds of thousands displaced.

Animals' Body Sizes Shrinking from Climate Change
https://phys.org/news/2019-07-animals-body-sizes-climate.html

University of Cape Town (UCT) researchers have collected clear evidence—over a 23 year period between 1976 and 1999—that climate change is shrinking animals' body sizes.

From the fossil record, it is known that during past periods of global warming, both marine and land-based animals have become smaller. And scientists have proposed that contemporary warming could lead to smaller animals, but so far, evidence supporting this has been scarce.

To investigate this idea and whether it could be true, the research team looked at a group of wagtails living along the Palmiet River. What they found supports the idea that climate change can shrink Earth's animals.

"All else being equal, larger animals can tolerate cold conditions better than smaller animals, so one could expect that a warming climate is relatively more advantageous for smaller animals," said Professor Altwegg.

"A lot of other factors also affect body size, though, so we weren't expecting to find clear temperature effects over a quarter of a century. Yet, the results clearly supported the idea that climate change was the reason why these birds became smaller over time," he added.

... The ramifications of this potential impact would extend beyond the organisms themselves, though. This effect of climate change could result in changes across ecosystems. Body size is an important indicator of an animal's fertility, lifespan and ability to survive times of stress, such as food shortages or drought. Body size also affects how much food an animal needs, how vulnerable it is to predators and what type of food it can eat.

Study shows saving elephants helps us fight climate change
Quote
What elephants eat and how they eat contribute significantly to forest biomass, research has shown.

The key novelty of the new study, by the ecologist Fabio Berzaghi and colleagues, is they include, for the first time, the effect of elephant feeding disturbances in a computer model that simulates demographic processes in forest ecosystems. They found that “elephant disturbance” – all that messy eating – results in forests having fewer, larger trees. Elephants filter out small early-succession (i.e. low wood density) trees, promoting the dominance of late-succession (high wood density) trees, which ultimately leads to long-term increases in the total biomass. Berzaghi and colleagues were able to validate their model predictions with data from real forest plots in the Congo Basin.

By promoting these larger, woodier trees, elephant feeding disturbances therefore mean the forest stores more carbon. ...
Arctic ice is healthy for children and other living things.
