Rising Sea Level Could Put East Coast Nuclear Plants At Risk 323

Posted by Unknown Lamer from the coal-industry-will-stop-at-nothing dept.
mdsolar (1045926) writes with news that global warming may make it more difficult to use modern power sources that rely upon being near large bodies of water for cooling. From the article: "During the 1970s and 1980s, when many nuclear reactors were first built, most operators estimated that seas would rise at a slow, constant rate. ... But the seas are now rising much faster than they did in the past ... Sea levels rose an average of 8 inches between 1880 and 2009, or about 0.06 inches per year. But in the last 20 years, sea levels have risen an average of 0.13 inches per year... NOAA) has laid out four different projections for estimated sea level rise by 2100. Even the agency's best-case scenario assumes that sea levels will rise at least 8.4 inches by the end of this century. NOAA's worst-case scenario, meanwhile, predicts that the oceans will rise nearly 7 feet in the next 86 years. But most nuclear power facilities were built well before scientists understood just how high sea levels might rise in the future. And for power plants, the most serious threat is likely to come from surges during storms. Higher sea levels mean that flooding will travel farther inland, creating potential hazards in areas that may have previously been considered safe." The article has charts comparing the current elevation of various plants with their estimated elevations under the various NOAA sea level rise estimates.

    The idea that these nuclear power plants are still relevant in 86 years should scare people more than any sea level rise. All those nuclear power plants are completely obsolete. If they need to be torn down and rebuilt elsewhere with new, safer, more efficient technology, we're all better off.

    I am a fan of both Anthony Watts' site Watts Up With That [wattsupwiththat.com] *AND* John Cook's Skeptical Science [skepticalscience.com]... both are run by real people who go the extra distance find the best links to their sources (not some blog chain) and both are considerate of the reader.

    Here's a small research journey: Direct CO2 rise causes temperature rise (CO2drivesT)? YES or NO?

    There has been a demonstrated correlation between CO2 and temperature shown by Antarctic ice core data (within ~800-1000y). If a rise of CO2 in this data should consistently lag behind rises in temperature then CO2drivesT is not ruled out (both may be responding to some other factor but at different rates) BUT CO2drivesT has fallen down a notch... it now requires more extraordinary proof.

    Even though human-driven global CO2 has risen 'terrifyingly fast' to 400ppm -- empirically speaking I am not terrified -- because the temperature rise that should accompany such a SHOCK by any reasonable interpretation of CO2drivesT, and to any reasonable extent, has not arisen. The effects of this 'causation' are missing.

    Which is to say the historical correlation is broken.
    That is not necessarily a bad thing. It's a thing,
    Something we should be concerned about.
    The rise to 400ppm is definitely humans' fault. It is 'massive'.
    Temperature has not risen.
    So such a causation, if any may exist, is unlikely to be significant.
    We'd see it by now.

    For example, head for Skeptical Science [SS] [SS] CO2 lags temperature - what does it mean [skepticalscience.com] which acknowledges that CO2 lags behind temperature but introduces 'CO2 amplification' which asserts a feedback where "the increased CO2 in the atmosphere amplifies the original warming.". This in itself is another extraordinary claim. While such a feedback might certainly exist I cannot just swallow it as a flat-fact when pursuing a simple answer to the CO2drivesT question. Where are the computer models incorporating this feedback that match observed temperature?

    There is a stir these days among CO2drivesT proponents that some mechanism must exist that is hiding or delaying the warming that the models predict. Immature 'skeptics' jeer at this, implying that it is all about protecting the sacred forced-feedback hypothesis at any cost. Immature CO2drivesT proponents accuse them of attempting to derail the scientific method. There is a germ of truth in both. I think everyone should grow up a little.

    Aside from the modern lack of warming, one thing seemed odd about amplification. In the Vostok ice core CO2+T [skepticalscience.com] graph clearly at ~75,000YA there is a massive injection of CO2 (~225-230ppm) that I think is Toba era volcanism [wikipedia.org]. If such amplification exists and is significant, that would have been a fine time for CO2 feedback to jump in and 'save the day' with a slowing or a plateau of the declining temperature trend. Or even a rise? But 6,000 years after its onset -- on the Vostok graph at ~220ppm temperature and CO2 are once again in lock-step, both in steep decline. After some six millennia of 'higher' CO2 and 'lower' temperature. Plenty of time for particulates to settle and 'amplification' to occur. If it does. Did it?

    But never mind, it's all changed, that [SS] Lag, what does it mean? [skepticalscience.com] page also said something astounding: "In fact, about 90% of the global warming followed the CO2 increase." 90%... is that a fact.

    Since when?

    Which led me to the next step where the game-changer is supposed to be [SS] Shakun et al. Clarify th [skepticalscience.com]

      If you're interested in the science of Anthropogenic Global Warming, I suggest you read the science, not blog posts. I've read both WattsUp and SkepticalScience, and they are both very poorly written and lack rigorousness. If you are reading these two blogs, you are reading the work of bias amateurs.

      Here's what you should be reading:

      • the peer-reviewed Journal "Nature Climate Change [nature.com]," which includes and references thousands of scientific papers on the subject.
      • he IPCC's 1,500-page "Physical Science Basis [climatechange2013.org]" report, clearly states what we know, don't know, and how we know it. It reviews its past predictions, notes where its models have errored, and takes into account an incredible wealth and scope of scientific observations over 150 years. I highly recommend downloading this 0.5 GIG report and at least skimming it. I consider it the model of good science [ideonexus.com].
      • The IPCC also makes all of its data and models available for review [ipcc-data.org]. So you can see for yourself. Take this data and give it to a machine-learning algorithm. The science of AGW is actually shockingly simple.
      • The US Government also recently updated it regularly scheduled report [globalchange.gov] written by over 300 experts.
      • If you don't trust the government, then I recommend The Berkely Earth Project [berkeleyearth.org]. It was funded by the liberal's favorite bad guys, the Koch Brothers, but its results were so compelling that the lead Climatologist, Richard A. Muller, wrote a piece for the New York Times announcing he no longer a skeptic [nytimes.com].
      • Of course, it's always good to have a contrarian viewpoint in the mix, and for that, I recommend AGW skeptic Judith Curry [judithcurry.com], who presents valid challenges to the consensus with her strong scientific background. I don't find her convincing, but her challenges make for good food for thought.

      Science, published peer-reviewed science, not blogs, is where we should keep this discussion.

    The US areas that are in trouble are mostly the Gulf coast, especially the Mississippi River flood plain and Florida. Florida is just barely above sea level now, and is very flat.

    Slight rises in sea level cause problems all along the Mississippi. Hurricane and storm driven flooding are already getting worse.

    The West Coast isn't so bad off, because there are cliffs along most of it. SF, LA and San Diego do have low spots, but they're a few miles long, and seawalls could be built. It might be necessary to dam the SF bay, with something like the Thames Barrage at the Golden Gate.

    South Florida has a population of greater than 6 million. Not only do we have nukes right on the beach we also have garbage mountains, graveyards that go back 150 years, chemical wells, and every other pollutant that a city tends to have. All of this is less than five feet above sea level. Most of it may be only two feet above sea level. The topography is such that the area will flood from the Atlantic all the way to the Gulf of Mexico. The region will not be habitable inland or on the coasts. Keep in mind we get high tides, spring tides, and hurricanes with surges as well as very tall waves. In other words a house on stilts would not help. Houseboats would have about a two year life span as tropical storms are common. So what you may say. Who gives a hoot about South Florida? the catch is that the pollution that would take place may well be enough to destroy the Atlantic ocean completely. South Florida also produces fruit and vegetables even in winter and there is no other part of the continental US that does that. On top of that the investment and mortgage value of south Florida is on a scale large enough to completely destroy the US economy if we go under.
