Although the situation is dire, it might not be as bad as you think.

This explains the methane

This explains the methane eruptions in the Arctic Ocean.

This research group filmed these methane bubbles during their research in the Arctic.

http://arctic-news.blogspot.com/2014/08/horrific-methane-eruptions-in-east-siberian-sea.html

Methane eruptions from the Arctic Ocean's seafloor helped push up mean global methane levels to readings as high as 1832 ppb on August 12, 2014.

Ironically, the methane started to erupt just as an international team of scientists from Sweden, Russia and the U.S. (SWERUS-C3), visiting the Arctic Ocean to measure methane, had ended their research.

Örjan Gustafsson describes part of their work: “Using the mid-water sonar, we mapped out an area of several kilometers where bubbles were filling the water column from depths of 200 to 500 m. During the preceding 48 h we have performed station work in two areas on the shallow shelf with depths of 60-70m where we discovered over 100 new methane seep sites.”

The coral reef is struggling

The coral reef is struggling to survive in Australia. We have been seeing an increase every year in the Gulf Coast of red tide. This is a toxic bloom of algae. It kills fish and people can't even go to the beach because breathing the sea mist causes illness from the toxins that are given off. Lake Erie had a toxic bloom of algae, this summer, that killed fish and also the toxin got into Toledo's water supply and people could not use it for days. One of the theories on the methane release that I commented on up thread may of been caused by organisms that live in the oceans that make methane. There was simply a massive bloom of them because of environment changes. These organisms are increasing in the warm seas.

Fish are very sensitive to temperature changes. The little tiny shell fish that create oxygen in the oceans are decreasing because of increase water temperature in some places. These little guys use up CO2 that is stored in the water and make oxygen in it's place.

So it is not just the matter of fish migrating to other areas, they just might find it hard to survive with out enough oxygen.

The ice sheets are our air

The ice sheets are our air conditioners that keep our climate balanced. With out them it could be too warm for us to survive. There is too much CO2 and methane in cold storage on the earth right now that will be released in the melt and surface heating. It is now thought that it was extreme methane release, that has been found in core samples dated at the end of the Paleogene period, may of helped caused the extinction of 2/3 of the plants and animals.

For now our winters will be colder and our summers hotter. The increase in water vapor in the atmosphere will cause wetter storms with extreme weather.

Back in my younger days,1974 to 1975, I learned to ski while stationed in Europe.

My first lessons were up in the Zugsptiz above Garmish ... it was a glacier that filled the entire bowl/slope. Now, there's hardly much of the glacier and it's under covers during the summer to keep the sun from melting what's left.

And the Stubital glacier I skied in early October of 1975 in Austria is hurting today as well.

I wonder if people realize the only way to revitalize a glacier is for another ice age to occur ???

Sounds like a Rachel Carson ... Silent Spring ... moment. Key point being the fishys.

I suspect cod is the predominate fish species in that region. So if the water temp is changing, then the schools will migrate to where the water temp is to their liking. Only problem would be an abundant food source in the new feeding area.

Or are cod tolerate of water temp changes along with food sources ?

In reply to Fascinating stuff, momoe.

You are welcome. I didn't know if anyone would be interested in this. It is a big international problem that don't get much media coverage in this country. People just can't wrap their minds around it because of the misinformation that has been put out by corporate interests for the last 40 years. It isn't happening in their front yards so they don't understand the urgency.

The Greenland ice sheet is now melting 5 1/2 times faster then when Al Gore made his movie. It doubles in it's speed every few years. Right now it is raining on the ice sheet in the south west corner of Greenland which it never does. Normally it snows all the time on the ice sheet even in the summer months. This just adds to the summer ice melt that provides the lubrication for the glaciers to move on. The ash from all the fires in the tundra located in Siberia and Canada has settled on the western side of ice sheet causing it to reflect less sun light. You can see the dark ash on the satellite pictures and it looks like dirty snow. Those areas are absorbing the sun's energy. This means loosing coastal areas a lot sooner then the models showed in the movie.

Weather is becoming more extreme. The jet stream is now weaker and slowing down which makes storms move slower. The scientist are worried about desertfication of California. There was a paper released on the rising of the mountains from the loss of the weight of the water and ice. Also the sinking of some valleys from the pumping of all the water from the aquifers in California. This comes from satellite surveys. Aquifer is not a renewable source. Once it is gone, it is gone.

We are in for a difficult time with land loss, weather, food and big hits to the economy.

Fascinating stuff, momoe.

While I am at it. There was a third paper released also from the University of Michigan Ann Arbor also yesterday. CO2 maybe released faster then in current predictions.

http://www.eurekalert.org/pub_releases/2014-08/uom-sct081514.php

"Our results suggest that sunlight, rather than biological processes, controls the fate of carbon released from thawing permafrost soils into Arctic surface waters," said aquatic geochemist Rose Cory, first author of the Science paper and an assistant professor in the U-M Department of Earth and Environmental Sciences.

Worldwide, permafrost soils contain twice the amount of carbon that's in the atmosphere. So thawing permafrost is a special concern for climate modelers trying to predict the timing and extent of future warming due to the ongoing buildup of carbon dioxide and other greenhouse gases.

But soil carbon does not instantly turn into carbon dioxide gas when permafrost thaws. It must be dissolved in water and chemically processed before it gets released into the atmosphere as carbon dioxide. Until now, scientists believed that bacteria were largely responsible for converting dissolved organic carbon into carbon dioxide gas in Arctic streams, lakes and rivers.

Here is more on the influence

Here is more on the influence of ocean currents on climate.

The slowing currents increased carbon dioxide (CO2) storage in the oceans, leaving less CO2 in the atmosphere. That kept temperatures cold and kicked the climate system into a new phase of colder, but less frequent, ice ages, the scientists believe.

"The oceans started storing more carbon dioxide for a longer period of time," says Leopoldo Pena, the paper's lead author and a paleoceanographer at Columbia University's Lamont-Doherty Earth Observatory (LDEO). "Our evidence shows that the oceans played a major role in slowing the pace of the ice ages and making them more severe."
