More Than 260 Airports At Risk of Getting Submerged Due To Sea Level Rise, Coastal Flooding: Study (weather.com) 171

Flights at hundreds of airports worldwide are in danger of being disrupted by rising sea levels, according to a new study. From a report: More than 260 airports around the globe are currently at risk of coastal flooding, and dozens could be below mean sea level by the turn of the century, the research published in the journal Climate Risk Management found. Hundreds more could be in danger depending on the amount of sea level rise driven by global warming between now and 2100. Airports in Asia and the Pacific topped the list. Researchers looked at several different factors to come up with the rankings, including the likelihood of flooding from extreme sea levels, flood protection and the impact on flights. They found that up to one-fifth of air travel routes could be affected.

    Oof dah, you can't make this stuff up. (Wait. Maybe you can, and that's the whole problem.) 8.2 feet of sea level rise in 80 years is a ridiculous number!

    Here, I'll even search that for you. According to NOAA, the sea level trend at Battery Park, NY is 2.87 millimeters/year with a 95% confidence.

    80 years of that trend will produce 9.03937 inches, not 8.2 feet.

    But hey, don't believe me. Believe "the Science" [noaa.gov].

    • Forgot the quote FTA:

      Globally, NOAA's worst-case scenario predicts sea levels could be as much as 8.2 feet higher in 2100 than they were in 2000. A rise of at least 1 foot by 2100 is considered very likely, even on a low-emissions path.

        I think that's assuming the Thwaites Glacier https://earth.org/antarcticas-... [earth.org] doesn't collapse. Just ordinary melting, and thermal expansion due to oceanic warming.

        A lot depends on what happens now, but it's also true that our current CO2 levels have already committed us to a sever warming trend...and we've only got guesses about how severe. It wouldn't be really surprising to see cotton growing in Canada at the end of the century. Unfortunately, due to the shape of the globe there's a lot less land tha

        I'm not sure what the point is of comparing "worst-case scenario" to "linear extrapolation based on current slope."

        The low-emissions scenario would basically keep the present rate of warming (the greenhouse gas we presently have is not going to vanish), so a better comparison between the two would be between the low-emissions case (which they call likely) and the current trend.

        There's a logic error in your post, by the way. You compared a prediction from 2000 to 2100 with an extrapolation from 2020 to 2100.

          Basically all models ignore the mass release of frozen methane, which of course will be the source of accelerated climate change. They also ignore new weather patterns, the rush of warm air up to the arctic, sucking up ice as water and of course pushing it back down south, where it dumps it as snow that melts and fills the seas faster (double plus, the flooding increase erosion and more flooding detritus rushes out to sea, raising sea level and rotting increases methane output).

      Relevant quote:
      "From the 1970s up through the last decade or so, melting and heat expansion were contributing roughly equally to observed sea level rise. But the melting of mountain glaciers and ice sheets has accelerated"

      In other words, the linear extrapolation you are doing is unlikely to hold. Instead the projection is for accelerating sea level rise. I am sick and tired of ignorance passing off as informed opinion. It's just like with the virus: at first it doesn't look bad, then it's a disaster seemingly all of a sudden.

        If you will actually visit the NOAA web site I referenced, you will see that the trend is IN FACT linear, and has been so literally since they have been collecting data back in the 1880s, not the 1970s.

        If you see a linear trend stretching back hundreds of years, the correct interpretation is that it will continue 80 more, not that it will suddenly change. That is an "extraordinary" claim, and extraordinary claims require extraordinary evidence.

        In the absence of such, you need to believe the historical data, not the theorized model.

          It is often very hard to detect exponential rise early on. The trend does not look linear but it takes a lot of squinting to see that. Just like with a virus, at first it looks minor then it explodes. You see the same thing with stock bubbles - at first it looks like a healthy appreciation then it suddenly goes into tulip mania mode.
          The issue is that in some cases, like in the case of a stock market, we do not understand all the driving forces so bubbles are hard to predict early. In the case of viruses and climate change we do know the causal relationships and can catch these exponential rises quite early. At that point, ignorant uneducated people who do know understand the underlying science have a hard time seeing any problem but that does not mean the problem is absent.

          • It is often very hard to detect exponential rise early on.

            Interestingly, temperature increase from AGW is logarithmic with regards to CO2. That is, every time CO2 doubles, an equal amount of warming is seen.

          Good data source, thanks for linking it.

          But to be fair, the article referenced says that the rate is increasing now, while the NOAA data is shows that the rate was constant in the past. Two different things. If what they are saying is accurate, then they are predicting a change in slope; but given the noise in the data, it will take another ten years or more before a change in slope will be visible enough to show up in the NOAA data.

Many people saw them, I get lots calls about those miserable diggers. We have to rid the country of diggers! Make Airports High Again! My terrific supporters like being high."

  • It makes a nice juicy headline to say "260 airports". But the first page of the report contains a panel that says
    The research looked at 14,000 airports worldwide.

    Flying is actually one of the mayor 3 causes of climate change (with eating Meat/Dairy and buying too much stuff). But then again...flodded airports are the least of our worries in sea level rising. How about cities? And the sea level rising itself is just one of the problems we will face: droughts, extreme heath, bushfires, low food production, milions of people on the move, etc.

    When I first came here, this was all swamp. Everyone said I was daft to build an airport on a swamp, but I built in all the same, just to show them. It sank into the swamp. So I built a second one. And that one sank into the swamp. So I built a third. That burned down, fell over, and then sank into the swamp. But the fourth one stayed up. And that’s what you’re going to get, Son, the strongest airport in all of England.

    How do you know we will still be using airports as we know them today in 2100?

For your example, LaGuardia had about 83,000 passengers per day in 2019. LaGuardia is a terrible airport but you have to replace that volume of passengers somehow if you get rid of LaGuardia.
