In Progress: Fastest Sea Rise In At Least 2800 Years (www.cbc.ca)

Layzej writes: A new study finds that sea levels on Earth are rising several times faster than they have in the past 2,800 years and are accelerating. Co-author Stefan Rahmstorf explains that the fact that the rise in the 20th century is so large is a logical physical consequence of man-made global warming. This is melting continental ice and thus adds extra water to the oceans. In addition, as the sea water warms up it expands. The data from the past can also be used for future projections, using a so-called semi-empirical model calibrated with the historically observed relationship between temperature and sea level. With the new data, this results in a projected increase in the 21st century of 24-131 cm, depending on our emissions and thus on the extent of global warming.

    The actuary tables don't lie. Insurance companies have accepted AGW for years now, no matter how much Big Oil and the Koch's try to deny it.

    You do realise the universe doesn't give a flying fuck about what you think about Climate scientists.

    Pretty much this. And, moreover, the universe doesn't give a crap about our continued existence, and won't take any special steps to save us.

    The problem is we're an exceedingly short-sighted species, and the near term profits of corporations are pretty much driving this process, and they'd rather have big executive bonuses now than give a fuck if there's a habitable planet down the road.

    I figure the only people actively denying climate change stand to make money from the status quo. Pretending it's not happening pretty much has no rational basis in anything else, because it doesn't otherwise benefit anybody.

    But it's the free market right? If all these insurance are over charging wouldn't other companies swoop in with lower premiums and steel all the business? Why don't they? Because they're genuinely afraid of they big payouts they'll increasingly have to make.

    You're thinking "Rising Oceans" are like a bathtub filling up. It's more like a statistical increase in flooding events. Exactly what insurance companies are leery of.

    When the responses are on the order of "how do we know the vase is broken?" or "prove the vase wouldn't have broken on its own" ... there are people who are trying to say "there is no mess, and even if there was a mess you can't prove it was us".

    You don't think those companies paying to fund stuff which says "nope, not happening" want to muddy the waters long enough to keep up profits for a while?

    I mean, when Exxon scientists identified climate change decades ago, and when Exxon spent huge amounts of money denying climate change, you can bet your ass that the denial of this comes entirely from corporate interests who don't want the source of their profits impacted, and they don't really give a crap how it affects everyone else.

    Corporations are, collectively, sociopaths. The longer they can convince you either there is no mess or that they nothing to do with it, the longer they can keep making huge sums of money.

    The people denying it's happening have a vested interest in misdirection and deception for as long as they can. Nobody has any other reason to deny it's happening other than the money they're going to make.

    This is the standard bullshit of the PR game ... keep publicly lying about it to confuse the issue, and pay to discredit the facts to support their own narrative. Complete and utter sociopaths with no regard for anything but themselves.

    Around 10 years ago, I sat in on a presentation by an insurance company exec who made an incredibly compelling case for the monetary cost of the global warming. Complete with facts and figures. Oddly enough, I haven't heard a lot of deniers cherry picking those numbers.

  12. Science Denial on Slashdot... by tekrat · · Score: 5, Insightful

    What's funny is that this is *Slashdot* -- where I actually come here for the comments, usually because Slashdot is inhabited by geeks, techs, programmers, scientists; i.e; People that should know a thing or two. Usually the discourse here is insightful and thought-provoking...

    And then comes a global warming post, and all the science deniers come out of the woodwork. You see posts as dumb as "It's snowing right now out my window -- global warming is a myth!"

    This is directed to all the deniers -- what are you people *doing* here on Slashdot? Do you actually work in the technology field and yet deny actual science?

    We *KNOW* there's too much CO2 in the atmosphere and we KNOW that it traps heat, so, what precisely are you denying?

    Or has Fox News tainted your perception of the world so thoroughly that when something comes up that clashes with your ideology you stick your fingers in your ears and scream "LALALALAL I can't HEAR you!" when presented with FACTS?

    Seriously, I don't understand why someone who denies science is on Slashdot -- why not also talk about how Black Holes are a myth, why we can't go beyond a 4Ghz CPU speed because God says so, and solving complex math is forbidden by the Bible? Maybe you'd prefer Slashdot articles on Ghosts, Chemtrails, UFOs and Bigfoot?

      First off, labeling anyone that disagrees with you as a "science denier" is neither insightful nor thought provoking so you might remove the plank from your eye before criticizing the specks in others.

      It is when you're talking to a science denier.

      How would you treat an anti-vaxxer or someone who denies evolution?

      We do not *KNOW* there's too much CO2 in the atmosphere. We are, at this moment in planetary history, at all time lows for atmospheric CO2. Historically we should be around the average of about 1600-1800ppm. Around 280ppm we would see plant life began to die off. We are damn lucky to be rebounding now. Yes, CO2 traps heat. We rarely hear about the way it does that is a logarithmic effect. The impact of going from 500 to 600 ppm is far lass than the effect of going from 300 to 400.

      So what if it is logarithmic. That doesn't mean trapped heat magically doesn't do anything at all. We are observing substantial changes in the ocean, not just sea level rise, but in the actual chemical composition as absorbed CO2 messes up pH levels. And we are also observing higher ocean temperatures, and lower atmospheric temperatures.

      As to planetary history, what the fuck difference does that make? Humans didn't exist in the Jurassic, and human civilization only developed in the last 10,000 years, not in the last 100 million years. Significant changes in climate will have, and are already having significant changes on rain belts.

      Trying to dismiss AGW by appealing to the fallacious view that it only counts when it is big increases is to betray intense ignorance of an entire discipline. What you're arguing is the equivalent of a Creationist saying "yeah well, we can only observe microevolution!"

    Having experienced Katrina I can assure you that insurance companies will simply ignore the law with relative impunity. Remember, it's a lot cheaper to simply buy yourself a few politicians, prosecutors, judges, and regulators than actually pay out massive claims during a major storm event.
