AURORAS ARE NOT AURORAS: Two nights ago astrophotographer Ruslan Merzlyakov went to the coastal wilderness of Denmark's Thy National Park and set up his camera for a long exposure of the Milky Way. He found the galaxy surrounded by aurora-like bands of red and green:

"It wasn't the aurora borealis," says Merzlyakov. "This was a magnificent display of airglow."

#Airglow is aurora-like #phenomenon caused by #chemical #reactions in the #upper #atmosphere. It gets started during the day when the air is illuminated by #ultraviolet #radiation from the #sun. At night the delicate afterglow can be seen from dark-sky locations like Thy National Park.
Green airglow is caused by oxygen. Red airglow is more rare; it is caused by OH. These neutral molecules (not to be confused with the OH- ion found in aqueous solutions) exist in a thin layer 85 km high where gravity waves impress the red glow with a dramatic rippling structure.

Who needs auroras? "The airglow," says Merzlyakov, "was out of this world."

#Climate #Change: #Journalism’s Greatest #Challenge

source: https://wblau.medium.com/climate-change-journalisms-greatest-challenge-2bb59bfb38b8

One climate journalist said to me: “I have the full support from my chief editor. I have even been given a budget increase. My #problem is now the foreign editor who doesn’t give me access to our foreign bureaus when I need them because my stories — supposedly are never as urgent as other breaking news stories — and my other and bigger problem are the news desk editors who don’t give my story a prime time slot or never quite promote it on social #media at the right time of day because they think it won’t perform well”.

...

In the most extreme of this behaviour, news organisations need to ask themselves whether this doesn’t amount to a form of editorial #greenwashing itself: To produce climate journalism so you can say you are doing it and so you can point to the URL’s of each published story while never really throwing the full #authority and distribution power of your news organisation’s brand behind it.

...

Given the foreseeable vehement conflicts over climate #policy in many countries, newsroom managers would do their staff and their journalism a favour if they now reviewed or updated their editorial codes of conduct to make sure there is at least a shared understanding in their #newsroom, a shared language on what they think the typical indicators of editorial activism are and — more importantly — of what clearly isn’t #activism in covering the accelerating climate #crisis.

...

At Agence France #Press, one of the world’s largest news agencies, their Global Chief Editor Sophie Huet is in the process of making sure that their bureaus around the #world include possible climate aspects in every story as naturally as they would already include possible financial angles of a #story.

Scientists raise #alarm over ‘dangerously fast’ growth in atmospheric #methane

source: https://www.nature.com/articles/d41586-022-00312-2

The growth of methane emissions slowed around the turn of the millennium, but began a rapid and mysterious uptick around 2007. The spike has caused many researchers to worry that global warming is creating a feedback mechanism that will cause ever more methane to be released, making it even harder to rein in rising temperatures.

Extreme Weather Events and Capitalism

The #Ice Is #Melting
The #Land Is #Burning
The #Ocean Is #Dying
The #Living #Planet Is #Unravelling
It's happening on our watch.
No more delays ...

#Climate #scientists around the world are alarmed by a triple climate-change-related crisis that hit the western U.S. and Canada in June and July.
Normally climatologists are careful in their assessment of extreme weather events, under pressure from energy industry profiteers and anti-science climate change deniers. They go to great pains to avoid being accused of exaggeration, and rarely (really never) point to climate change as the cause of specific freakish #weather events.

The severity of what has happened in June and July has pushed past many of their carefully calculated projections. The fingerprints of capitalist-induced global warming are all over the crime scene.

A severe #drought in the western states of the U.S. that has been worsening for months has nearly drained Lake Mead in Nevada, Lake Oroville in California and other major reservoirs, threatening #power #generation for millions of people. A series of intense, widespread, sustained heat waves tortured a quarter of the U.S. as well as western Canada for weeks, taking the lives of hundreds of people.
The super-dry conditions in the region have caused 83 wildfires, including the Dixie Fire in northern California and the Bootleg Fire in southern Oregon. They are two of the largest #wildfires in #history and are both still raging.

Mild Pacific Northwest goes wild

The southwest U.S. is no stranger to deadly heat, but what is most unexpected is that this extreme heat has hit the Pacific Northwest, a region known for mild temperatures and damp weather.
Roads buckled in Seattle from the sweltering heat. For several days Portland, Ore., was the fourth-hottest place on earth. British Columbia suffered the highest death toll with more than 800 deaths between the end of June and middle of July — quadruple the average number of deaths.
The village of Lytton in British Columbia burned to the ground just as Paradise, Calif., did in 2018 — essentially nothing left but ashes and smoke.
In Canada’s British Columbia province, and the U.S. states of Washington, Oregon and northern California, the heat broke all-time temperature records, and then broke those records again, and then again.

Electric power for millions threatened

Nevada and California’s livability depends on a system of 1,500 human-made reservoirs, not only for drinking water and agriculture but for electricity from hydroelectric generators.
Engineers say that the water level in Lake Mead will be below the minimum water level needed to generate power to 1.3 million people in a matter of days. Lake Oroville will likely last until September, when it won’t be able to supply electricity for another 800,000.
Normally, power companies buy power from nearby regions when needed. But constantly running air conditioning in a wide swath of the western U.S. during 2021 has diminished power surpluses that normally allow that to happen.
All told, the fires have burned 1.3 million acres — an area larger than Los Angeles, New York City and Chicago combined. The smoke has journeyed cross-country to the East Coast, prompting air quality warnings along the northern part of the Eastern Seaboard and as far inland as central Virginia.
In addition to California, Oregon, Washington and British Columbia, the heatwaves hit Nevada, Arizona, New Mexico, Utah, Colorado, Wyoming, Montana and Idaho.

Heat deadly for agricultural workers

Thirty-eight-year-old Sebastián Francisco Pérez from Guatemala was working at an Oregon tree farm on June 26 when he collapsed and died from the heat. The Bureau of Labor Statistics reports that 53 #agricultural #workers died from heat nationwide in 2019, but this was the first in Oregon directly attributable to heat.
Only four states have laws in place to protect farmworkers. Oregon became the third after the death of Sebastián. Washington State quickly followed with some emergency measures. Some other states merely have “guidelines.”
Irene Ruiz, an #environmental #justice organizer from Boise, Idaho, messaged about the heightened danger to agricultural workers during heatwaves. “Guidelines are not enough. These are the people who put food on our tables and are the most affected and in danger of extreme heat.”

#Imperialism and #globalwarming

Recent decades have seen extreme weather events become more frequent and much more severe than previous periods. Experts point to that quickening pace and increasing severity as caused directly by global warming, even though they usually avoid blaming global warming for specific weather events.
The opposing narrative, motivated by energy profiteers, is that the warming of the atmosphere during this period is a natural cycle, that it has happened before over the millennia, and that it will pass.
But a #scientific #paper published in the journal Nature on July 28 referenced two large, decades-long studies of the #Earth’s “ #energy balance” — the amount of the sun’s energy entering Earth’s atmosphere compared to the amount of energy reflected back out into space. Both studies confirm that greenhouse gases are keeping the sun’s energy trapped in our atmosphere.
The paper asserts that there is less than a 1% chance that the rise in global temperatures and all of its frightening consequences are a natural occurrence.

#Greenhouse #gases began to heat the #atmosphere with the dawn of #industrial #capitalism in the latter part of the 19th century. That much is readily admitted in the capitalist press these days. What isn’t written about enough is the role of imperialist domination in this crisis for #humanity.
The machinery of war is the greatest consumer of oil, and like a dog chasing its tail, pollutes the world while fighting to control oil markets. If the #US military machine were to be ranked in the list of countries that indicates how much they contribute to pollutants that heat the atmosphere, the list would show it ahead of 46 countries.
Estimates of the cost of stopping global warming vary from $300 billion to Forbes Magazine’s price tag of $50 trillion. Underdevelopment and poverty have been imposed on much of the world by #imperialist #military #force and #economic #leverage for more than a century. The stolen wealth is now concentrated in the hands of the tiny group of billionaires that have profited immensely — as a class — from the control of oil markets. That stolen wealth is key to mitigating climate change.

The world is being told to put its faith in international agreements to solve the crisis. The #ParisClimateAgreement is supposed to oblige each participating country to limit greenhouse gases and commit rich nations — and in some cases private corporations — to help fund efforts by poor nations with $100 billion per year in grants, loans and other forms of financing, to help them switch to clean energy.
That agreement still shifts the blame to the poorest countries, when in fact 20 industrialized countries are responsible for 78% of greenhouse gases.
Historically, no country has put more carbon dioxide into the air than the imperialist U.S. #empire. The ultimate goal of the Paris Agreement is to limit greenhouse gases to a 2% increase per year, and “if possible” to 1.5% per year. As of today, the rich countries haven’t come up with the first $100 billion that was due in 2018.

Over the past few days the #weather has been settled owing to there being a #HighPressure region over us. The #pressure is now dropping and air from other parts of the world will start to rush in and inevitably, different air masses, at varying temperatures and humidities will mix. This sets up perturbations in the #atmosphere and steady #TemperatureGradients get perturbed and so, instead of having #clouds with flat undersides, they start to show undulations (spatial oscillations).

This evening, this is the what part of they #sky is looking like.
Clouds and the Sun

Here's a view in a slightly different direction. I think there is a certain grandeur to these beautiful forms.
