Bill Nye Explains That the Flooding In Louisiana Is the Result of Climate Change (qz.com)

Reader mspohr writes: Our favorite science guy has an interview (and video) in Quartz where he explains how Louisiana flooding is due to climate change:
"As the ocean gets warmer, which it is getting, it expands," Nye explained. "Molecules spread apart, and then as the sea surface is warmer, more water evaporates, and so it's very reasonable that these storms are connected to these big effects."
The article also notes that a National Academy of Sciences issued a report with the same findings: "Scientists from around the world have concurred with Nye that this is exactly what the effects of climate change look like, and that disasters like the Louisiana floods are going to happen more and more. According to a National Academy of Sciences report published earlier this year, extreme flooding can be traced directly to human-induced global warming. As the atmosphere warms, it retains more moisture, leading to bouts of sustained, heavy precipitation that can cause floods."

      Absolutely correct. What people forget is that the Mississippi used to have flood plains all along its path. When there was heavy rain anywhere along its course, the waters would raise and it would overflow its banks depositing rich soil and silt all along the way. Now, we've replaced the flood plains with housing developments and mini-malls. The rich soil deposited by the Mississippi is under asphalt. (Well, not all of it.) Additionally walls, dams, and other barriers have been constructed by various municipalities and the US Army Corps of Engineers to keep the Mississippi from overflowing its banks. This creates a situation where additional water has no where to go other than to cause the water level to raise and for the river to run faster (such as water flowing through a pipe.) When it gets down to coastal LA, it is traveling much faster than it would naturally and is causing massive erosion. Additionally, it causes major floods as the pent up water finally has a place to go. Government planning at it's best. (Thanks US Army Corps of Engineers!)

      You nailed the reason for the sinking Mississippi delta we're hearing so much about today. Because deltas are made of silt, all of them slump and sink over time. In nature, they are kept alive by annual flood depositions of fresh silt from upstream. Because of Corps of Engineers reclamation, the Mississippi is flowing clean and the delta, even the part that is not built on, is no longer getting fresh silt.

      If we want to save New Orleans, why not drill a grid of injection wells citywide and pump fresh mud at an even rate into each one to keep the city afloat?

You could clearly detect the host's frustration as he attempted to get these hapless officials back on the rails speculating about climate and saying disparaging things about fossil fuels.

    As with any branch of science that uses statistics, no one can say that any specific event has a specific cause where multiple causes are possible. For instance, you can't tell whether a specific decay event in a lump of plutonium was caused by radioactive decay, or maybe a stray high energy cosmic ray. But what you can do is measure a large number of decay events and come up with the most probable explanation. This is true of all statistics, and it's why we have tools like statistics.

    So if anyone points to a specific storm and says "That's AGW", they're not going to get much support even in the climatological community. But if someone states "The number of major floods and the intensity of those floods is increasing, and the most likely agent is AGW", well that's a statement of probability.

    I agree with you about Bill Nye not pointing to climate change as the sole cause of the flooding. Had he said that, I'd think he was a complete idiot. Of course climate change has to do with almost every weather pattern. However it's worth pointing out that every few years, some random town in America (and in other parts of the world too) floods to a large degree, and has ever since I can remember (I was born in the mid 70's).

    It's also worth pointing out that the water level has been rising at a noticeable rate for the last 10 years or so. I live near the ocean, and I've watched boat launches and piers go underwater during high tide, where that never use to happen. I wonder how much of this water rising had to do with, and will have to do with in the future, Louisiana flooding. They're basically already underwater in the lower parts of the state, so much so, that they cannot bury their dead in the ground, due to ground water being so near the surface. My hunch is that the ground water rising is the main contributor to flooding at times like this.

Depending upon where the irrigated desert farmlands are, altered precipitation patterns as a result of transpiration should also flood below sea level, especially the newer higher one, current deserts (think places like https://en.wikipedia.org/wiki/...).

    We may still get periods of smaller and less frequent storms even with extreme global warming just as we do today. The probability of those periods occurring, however, will decrease. The system is far too complex to point to individual events and say, "This was directly caused by X," because that event could have occurred without X, too.

They've made one of the supreme challenges of humanity at this point of time and politicizing it for their own ends). The conservatives, on the other hand, are often just people easily manipulated by large commercial interests who want to delay significant responses to AGW long enough to maximize profits. That's why the fossil fuel companies fund crap "think tanks" like the Heartland Institute, because they serve to give conservative and libertarian types a pack of memes to trot out every time the topic of global warming comes up. A pox on both their houses, I say. Both groups are populated by idiots and demagogues.

    To my mind, the time has come to simply look at the best way of dealing with the problem. For me, the simplest way and the way that it is the most market oriented is carbon pricing. Start upping the price of fossil fuels, thus allowing market forces to concentrate investment on alternatives. I don't even care if governments pocket the cash. The whole point isn't reinvestment of carbon taxes, but rather to create an artificial scarcity. This solution should be eminently favorable conservatives and libertarians, because it favors their economic approach, but of course, it will cost the likes of the Koch Brothers money, so the game goes on.

    Tropical cyclone accumulated cyclone energy (ACE) has exhibited strikingly large global interannual variability during the past 40-years. In the pentad since 2006, Northern Hemisphere and global tropical cyclone ACE has decreased dramatically to the lowest levels since the late 1970s. Additionally, the global frequency of tropical cyclones has reached a historical low. Here evidence is presented demonstrating that considerable variability in tropical cyclone ACE is associated with the evolution of the character of observed large-scale climate mechanisms including the El Niño Southern Oscillation and Pacific Decadal Oscillation. In contrast to record quiet North Pacific tropical cyclone activity in 2010, the North Atlantic basin remained very active by contributing almost one-third of the overall calendar year global ACE.
