Large amounts of sulphur dioxide inthe Arctic atmosphere - what does it mean?

My intention was to do a video on this. 

However, from the moment I switched my computer nothing would work. First, the software for showing the pictures (Preview) would not open; then Quicktime, which I use to record the movies would not open and when I did would not allow me to save or export my file in any form onto the desktop.



Large amounts of sulphur 

dioxide in the Arctic while 

methane levels in the mid-

atmosphere appear to have 

reduced

Some may see it as a "solution" to climate change but it is another sign of the growing human predicament

Today, I came across a posting from Harold Hensell on Facebook in which he posted this picture of methane levels at 500 hHz.


He contrasted it with this from mid-January where, as you can see there are humungous amounts of methane at that altitude.



He posted this with the following comments which seem to be a tad myopic to me.



" I don't have an explanation for the decrease but whatever it is, I hope it keeps doing it"

---Harold H.Hensell


As can be seen from this methane report from a few days ago there is no lack of methane coming from the surface




Something else has to be at play here.

Thanks to Margo's regular monitoring we know of two volcanic eruptions...

One was from on one of the Kuril islands at the base of the Kamchatka Pensinsula in the Russian Far East...



And in New Guinea.



Margo has been covering this on a regular basis. Just from this (from 25 June) you can see the spread of sulphur dioxide in the Arctic and Pacific region.





And going forward a few days.




Now, looking at the global total column you can get a further sense of what is happening.

And in the Arctic...



Looking at the global view at 500 hPa one can see that the biggest concentrations of sulphur dioxide are in the higher latitudes of the Northern Hemisphere.




Here is global view of surface level sulphur dioxide.

One might expect that one might get an indication of high levels of sulphur dioxide where the volcanoes are situated.

This appears not to be the case but there are prodigious quantities of sulphur dioxide in the Arctic and this has had an effect on methane higher in the atmosphere but not at the surface

The question that no one appears to be even asking having failed to notice this.



Once again we have people making superficial observations and failing to look any deeper or asking why this might be.

That takes time and effort.

P.S. I have no idea what the effects of trace amounts of sulphur dioxide in the atmosphere coming down when it rains - acid rain?


But there is this...

What is sulfur dioxide?

Sulfur dioxide (SO2) is a colorless, reactive air pollutant with a strong odor. This gas can be a threat to human health, animal health, and plant life.

The main sources of sulfur dioxide emissions are from fossil fuel combustion and natural volcanic activity. Hawai'i Volcanoes National Park (NP) is unique in the national park system because it sometimes has extremely high concentrations of sulfur dioxide — far higher than any other national park, or even most urban areas.
How can sulfur dioxide affect your health?

Sulfur dioxide irritates the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO2 can cause inflammation and irritation of the respiratory system, especially during heavy physical activity. The resulting symptoms can include pain when taking a deep breath, coughing, throat irritation, and breathing difficulties. High concentrations of SO2 can affect lung function, worsen asthma attacks, and worsen existing heart disease in sensitive groups. This gas can also react with other chemicals in the air and change to a small particle that can get into the lungs and cause similar health effects

And seen in relation to climate change

When faced with the crises of irreversible and extreme climate change, scientists have proposed harnessing sulfur dioxide to cool off the planet. Scientists have also urged for multiple countries to work in tandem to significantly reduce dangerous gas emissions caused by industry and transit.




According to Science Direct, humans have known of sulfur's dangers to health and environment for centuries. During an incident in London during 1880, over 1,000 people perished as a result of contact with toxic sulphuric gasses released from combustion of coal.


When sulfur compounds reach the atmosphere, it is when they come into contact with air and water that they become transformed into more lethal and deleterious substances.

Chiefly, sulfur compounds readily become sulfuric acid, acid rain, and cause corrosion to human structures. Also, animals and plants can meet a fatal end when making contact with sulfuric compounds.


One reason sulfuric oxides are so detrimental is that they are hard to remove from the air, soil, and water. Additionally, when there is acid rain present, the inability of natural surroundings to stay alkaline or neutral for optimal health becomes nearly impossible.....


...Volcanoes may be a naturally occurring source of these sulfur-based dioxides. However, when it comes to human-created emissions, the burning of coal at power plants, oil, and natural gas used in vehicles is largely to blame for air pollution and environmental problems….



...Acid rain is created when dioxides come into contact with rain clouds, creating sulfuric rain that is damaging to lakes, rivers, and trees. Aquatic-based wildlife can quickly succumb to a fatality or defects brought on by acidification of their watery environment.


.When fossil fuels are burned to create energy to power cities, transportation, and manufacturing processes in industry, one of the more significant greenhouse gasses that are emitted is sulfur dioxide.


The problem with greenhouse gas emissions is that it not only gets trapped in the atmosphere with no escape, but it amplifies and reflects heat causing temperatures to soar.



When humans and wildlife are faced with inescapable heat that lasts for long stretches, it can be fatal. Additionally, extreme temperatures put a strain on current crumbling infrastructure for electricity, heating, and cooling.

I remember there was a lot of talk about acid rain in the early 1980's and it was supposed to be behind us.

Looks as if it is back!

Doesn't sound like a "solution", does it?

Imagine what acid rain means for the Arctic ice.
