Super Pathway Discovered In Southern Ocean 167

Posted by kdawson
from the been-there-right-along dept.
WaltonNews writes in to let us know that a major underwater current called the Tasman Outflow has been discovered by Australian scientists. It helps to regulate the Earth's climate by providing water flow between three oceans in the southern hemisphere. Relatedly, a senior climate scientist has called for the establishment of a Southern Hemisphere network of deep ocean moorings, to complement the network already established in the North Atlantic. The intent is to detect any change in ocean circulation that may adversely influence global climate.

    Al Gore already figured ALL OF THIS OUT.

    There are no natural processes which affect climate. We all know what affects climate, is our use of incandescent light bulbs!

    If only we'd all switch to mercury filled compact flouros, we'd reduce this nations energy consumption by almost 0.005%! Not only that, we'd increase the amount of mercury in our groundwater by over 200%! Mercury is good for you and helps build strong bones and teeth.

    Also, we should junk our existing cars and build and purchase new ones which are marginally more efficient.

    WHEN WILL WE LEARN?! THE ONLY SOLUTION TO CLIMATE PROBLEMS IS TO SPEND SPEND SPEND SPEND ON COMPANIES AL GORE HAS STOCK IN.

      Nearly all of the major news reporters are simply trying to make big headlines (save for several which have their own agenda's). All will spin in to suite their purpose. A good example was back in the 70's, a scientist say that climate change WAS happening and suggested that it COULD lead to global cooling. From that, a number of the articles came out that pushed that. So, quite paying attention there.

      Pay attention to what the real scientist are saying directly. Get past what fox news and oil companies have to say. Listen to the top ones (such as Dr. Hansen who is one of thousands ) and even ones like Dr Grey ( from Colo State, who is one of the very few accredited skeptics). It is a good thing to pay attention to both sides, just skip the garbage.

Until they throw out any temperature readings taken within the area of influence of metropolitan areas all of their models are complete bunk.

    We should tap these ocean currents for energy. We should have machines somewhat similar to wind turbines, anchored to the sea floor, floating in the middle of the flow.

    These flows are far more steady and reliable than the wind. And no pollution. A great source of energy.

        "Unsuccessfully"? The article that you link to says their price is already only slightly higher than traditional energy production. That sounds extremely good for such an early stage in new technology.

        Bugs are to be expected in the beginning. Saying that they are unsuccessful just because they have bugs is like saying that a programmer is unsuccessful because he's debugging his program.

        Of course there could be other problems not mentioned in the article. But from the information in the article I'd say their

As far as I can tell, every time they try putting the turbine in the river, it breaks. If you installed a program and it crashed every few minutes, would you call it successful?

          I commend them for their progress and continuing efforts to get this working. I'll call it successful when it's down there and generating electricity for a significant amount of time.

            If you installed a program and it crashed every few minutes, would you call it successful?

            No, if it was marketed as finished, and yet crashed every few minutes, I would indeed call it unsuccessfull. But if I'm writing a program, and it crashes every few minutes while I'm writing it, I'd call it unfinished. Whether it's successful or not is at that stage not defined by whether it crashes or not.

            I suppose we have different impressions about what stage of development they are in. I do see your point, and you could be right, but I'm not convinced, not with the information I've seen so far.

  • Rather than arguing about the cause of climate change, we need to focus on solutions to the problems it is creating, and monitoring of the climate.

    We need to come up with solutions.
    For example, if we had a way to do desalinzation on a massive scale, we could pump billions of gallons of water inland into the continents of Africa and Asia. This would solve the drought problems by providing fresh water, and it would also reduce sea level.
    We could dig massive holding ponds in the middle of Africa, and/or use n

      The efforts you suggest would change the climate. The climate change debate says that we need to stop change. It does not say that we need to work on technologies to make our lives better.

      Well, I suppose if you like treating the symptoms rather than the cause. But then again, we haven't identified all of the causes and their extents a this point, so perhaps the best we can do is largely treat problems symptomatically for now.

      While no doubt what you suggest as "conservation corps" project would certainly do good in Africa, its effect on climate change would probably be relative to pissing in Lake Superior to raise the water temperature.
