Maine study finds potentially disastrous threat to single-celled plants that support all life
Source: BDN
BOOTHBAY, Maine Phytoplankton. If the mention of the tiny plant organisms that permeate the worlds oceans isnt enough to pique your interest, consider this: They produce the oxygen in every other breath you take.
Still not interested? This is where its hard not to take notice. In 2007, the reproduction rate of phytoplankton in the Gulf of Maine decreased suddenly by a factor of five what used to take a day now takes five and according to a recently released study by the Bigelow Laboratory for Ocean Sciences in Boothbay, it hasnt bounced back.
So what does it mean? According to Barney Balch, the labs senior research scientist and lead author of the study, such a change in organisms at the bottom of the planetary food chain and at the top of planetary oxygen production could have disastrous consequences for virtually every species on Earth, from lobsters and fish that fuel Maines marine industries to your grandchildren. But the 12-year Bigelow study focused only on the Gulf of Maine, which leads to the question, will it spread?
I dont think it takes a rocket scientist to know that if you shut down the base of the marine food web, the results wont be positive, said Balch.

If news media still had actual science reporters, and if editors were interested in educating the public, and in reporting actually important news as opposed to trivia about the latest celebrity-du-jour or shallow, misleading stories about the presidential race, maybe it would ultimately become front-page news.

(21,088 posts)The problem is too abstract;
The effects are apparently well into the future;
The effect is just being noticed;
The fix isn't known at this time.
Humans have something called a "hyperbolic discount function", that arises from our evolved brain structure:
Why is it so difficult to generate concern for events that are seen as belonging to the future even though their consequences may be dire? It happens because of the way we're wired.
Millenia of natural selection favoured people who responded immediately to threats or rewards. Individuals that did not immediately run from the tiger were more likely to become the original Darwin Award winners. This selection reinforced our responses to immediate and clearly understood rewards or dangers. The further away in time the reward or danger was, the lower our response to it became, because its influence on our survival was correspondingly less. Even if we waited to run until a distant tiger got closer, the chances were good that we would escape anyway, so there was no need to leave our meal just yet.
This idea is known as the "discount rate". It's the same concept used by banks, where the present value of a future event is discounted depending on how far in the future it will happen. While banks use a linear discount rate (expressed as a percentage), there is strong evidence that human beings use a more complex function that comes from different parts of our brain. The more primitive parts (the brain stem and limbic system) are concerned with immediate survival and emotional responses. They are much less capable of long-term evaluation, but provoke the strongest reactions to pleasure or fear. The neocortex, on the other hand, is our thinking brain. It analyzes, predicts and plans for the future, but has more limited access to our emotional triggers.
As a result, immediate threats or rewards that require no deep analysis tend to activate the "older" portions of our brain and prompt very strong responses. More abstract threats and rewards identified through the analytical capability of our neocortex don't activate our limbic system, and so usually prompt a much less intense reaction. Immediate, concrete concerns always strongly outweigh distant, abstract ones. The discount function is called "hyperbolic" because it falls off very rapidly at first, then flattens out as time passes. Events that are very near term evoke a sense of urgency that falls off steeply as the time horizon passes from the domain of the limbic system to the domain of the neocortex, resulting in the characteristic shape of a hyperbolic curve:

GliderGuider
(21,088 posts)It depends on the degree of climate change. If we've created a world in which a +6 degree C average temperature rise is the outcome, we probably won't survive as a species. Certainly a +8C world would do us in.
We won't know for sure for a while, and if extinction is in the cards it will probably play out over the next 200 to 500 years.
I'd spend more time worrying about it, but I have to drive to Denny's for some dead cow.

(21,088 posts)Humans have proven themselves to be extremely innovative survivors in all kinds of "suboptimal" environments. Short of a massive asteroid strike, human extinction will take what seems to us to be a long time. In geological terms though, it will be the blink of an eye.

(9,001 posts)might make you feel better, but in the end accomplishes almost nothing. However that energy, spent in concert with the like minded becomes a force. Because it's changing the actions of the mega-polluters (agri-biz farms, coal fired power plants, corexit using oil companies) that can actually have substantial impact.
But that means enacting laws and we know where that cul-de-sac ends up.
"Personal virtue and atomized action will not prevent disaster, because personal evil didnt cause the problem. Its political dysfunction thats driving us into the ditch: Capture of our politicians, our elections, and our public discourse by those whose revenue streams depend on the continuation and expansion of a fossil fuel economy."
And yes, I realize that part of why we are here on DU.
But I often see this framed as a problem of "personal virtue", to reference the quote and it is not. Not by a long shot.
GliderGuider
(21,088 posts)I no longer think of my actions in terms of "saving the planet" or whatever. I tried that for a while and it made me crazy. I now think of them simply as making my own life better.
I have adopted a very "Eckhart Tolle" outlook on on the future - it will unfold from the present according to its own dynamics. My role in that process is to tend my own metaphorical and physical garden. It's a lot easier to live this way, I find.

(5,178 posts)But then I'm also of those people who think that many great changes have started from a single person rising from the sea of the easily discouraged.
It may well be the proverbial "lost cause". Like Unions in early industrial America or someone stopping an old growth tree grove from being turned into a Dairy Queen or a myriad of other things. People can't sit back and say "Well, I'll change when everyone else does.". It demands much more than that. It requires an unrelenting and overriding desire to create better conditions & lives for kids & kitty cats and all the other critters on earth. That the idea of supporting that is the right way and in fact, the only way. That it may find a spark in one final person that finally tips the cart over is the only hope we really have.

(42,239 posts)discolouration of the water due to all the shit reaching the sea.
See here :
Though heavier water flows into the Gulf of Maine might be a major factor, Balch said it may actually be side-effects of that phenomenon such as decreased salinity and increasing amounts of materials like rotting plant matter being swept up in the stronger currents that are actually causing the problem. In other words, when the water is brown its bad for phytoplankton because the added material in the water starves the single-celled plants of sunlight.

The type of phytoplankton found near coasts can bloom rapidly when there are changes to the amounts of light and nutrients available. Some blooms are toxic for humans and marine life.
The articles aren't really contradictory, but it is funny to see them both the same day... and the combination demonstrates how little we know and how complicated all the interrelations are.
