#93 – Mister Mustard,
Potland??? Can you get there by 4:20???
We got a long way to go and a short time to get there …
That’s what you meant, right Bandit?
Scott–if you have the time, I’d still be interested in your thoughts to my question at #51. And to that I will add just saw again the tv show “The Big Chill” about fresh water coming out of Russia and the Ice caps may stop the Atlantic Conveyer at any time, a 50/50 probability in the next 100 years and snow on the ground for 100 days a year will occur in England. Another consequence of global warming: melting ice and changing the salinity of the ocean==a gotcha that will probably happen before the ocean rise of “global warming” is fully recognized. We are living in interesting times, I pity our kiddies.
BTW on the car deal–I recall GM selling straight 6’s with manual transmission that got worse mileage than the same car with a v-8 automatic. You also got worse mileage if you put larger tires on the car. So–all the parts do work together. I’d be happy to take a penalty in acceleration to up my overall mileage. I don’t see any economy cam’s in the speed magazines.
#51, 95 – bobbo,
Sorry I missed that question earlier. It’s an excellent question. I’m not sure whether I’ve read any articles that specifically state that the collapse of the ocean food chain would kill humanity.
However, I have read numerous articles that I was just reading that the oceans are becoming acidic far more quickly than we expected. I’ll look for the reference after I type this.
The real issues with the increasing acidity, in the form of carbonic acid, are 1) shellfish will be unable to form shells as they will dissolve as they are being created and 2) as the ocean absorbs more CO2, it becomes unable to absorb more. So, the more CO2 already in the ocean, the less the ocean can pull from the atmosphere to reduce warming.
The issue with shellfish is that shellfish such as krill and other creatures are the base of the ocean’s food chain. Many of the ocean species upon which we depend may go extinct without this base. Since a billion people depend on ocean seafood for the bulk of their protein, this will be disastrous even if not fatal to our species.
Here’s the article I was thinking of. It is probably exactly what you are looking for with the exception of the fact that the study did not go as far as to examine the exact impacts to humanity of having the oceans in this state. This article is for a general audience but does cite a peer reviewed source in the journal Science.
Oceans turning acidic decades earlier
Thanks for reposting your question bobbo. Sorry I missed it the first time.
bobbo,
You may also be interested enough in the topic to sign up for the Climate Crisis Coalition newsletter. I get it once a week. It gives a good overview of what’s going on and usually has links to more detailed stories. When those stories do not have links to the real research, it is usually not too hard to then use google scholar to find the original if the general article seems to miss the point or is a bit vague.

#96–Scott==great/scary link.
I feel like we are playing dodge ball with our civilization. One ball might be ocean rise. Another is ocean acidification. Another is change in salinity. No matter how could you can twist and dodge, when the number of balls increases, your time on the basketball court is reduced.
#95 – bobbo,
Regarding the decrease in salinity of the ocean, it is a big factor in the slowing of the ocean conveyor currents, which have already slowed by 30%. In the extreme scenario discussed in Under a Green Sky, this is a huge factor in causing the ocean currents first to stop and then to start up very differently leaving warm water all the way to the depths of the ocean.
Since warm water dissolves less oxygen, the anoxic ocean ends up not supporting today’s deep see life. Instead, bacteria breed there that produce sulfur. Gradually the anoxic and mostly lifeless layer gets closer and closer to the surface. Once it breaks the surface, the ocean belches forth toxic levels of hydrogen sulfide gas into the atmosphere.
This was the cause of the Permian/Triassic extinction 250 million years ago. It was the worst of the six mass extinctions the planet has seen. (I’m including the current extinction event in the six.)
If we allow/cause this to happen again, we and most other multicellular life on the planet will not survive. Let’s hope this worst case scenario does not happen.
As for your comment about “our kiddies”, it won’t be my kids dealing with it. (I hope the HTML below works, no preview here.)

Oh well. The GIF didn’t come through. Oh well. For anyone who wants to see the award gif, please follow the link. It’s cute.
#99–Congrats. I achieve the same effect by not shaving.
The USA has very low gas taxes. The cost of gasoline is mostly graft on the part of the oil companies and the oil investment speculators, not to mention a president and a republican controlled congress that let it spiral out of control without lifting a finger.
If this had occurred under Clinton, he would have been impeached, imprisoned, and then forced to live on an island somewhere, but its Bush so its okay.
