  • This whole article boils down to one thing. We know that the earth is warming and is going to continue warming but we can’t model the effects on a local scale. The problem is simply too complex for our current models and our current computing infrastructure.

    The absolute best climate models have horizontal resolutions on the order of 10km. That means that there is one value for temperature every 10km, one value for water vapor every 10km, one value for north-south wind speed every 10km, one value for east-west wind speed every 10km.

    Of course we can’t model hyper local climate effects! We have one pixel every 10km to help us understand an immensely complex system and how it is changing over hundreds of years!

    Hell, we can barely model hyperlocal weather effects! We have high resolution satellite measurements every 10 minutes over the entire globe. We know where everything is and can give the models very good initial conditions. Yet we still can’t say whether it will snow in your neighborhood tomorrow. We can give a probability, but nothing certain.

    If, given high resolution initial conditions for modeling weather, we can’t model a neighborhood’s weather accurately, why would anyone think we can accurately model hyperlocal climate effects?

  • It is amazing to me how short our memories are as a species. There are people who are still in congress who had polio. There are an estimated 300,000 people still alive in the US who survived polio. Even with that, the nominated head of Health and Human Services wants to do away with the polio vaccine.

    I don’t know what the problem is. Is it a lack of empathy? Is it willingness to swallow the bait surrounding conspiracy theories? Is it just a lack of education? How did we get to the point where it is even remotely okay for the future head of Heath and Human Services to be against the polio vaccine?

    If being pro-polio isn’t disqualifying for being the head of HHS, and if he gets confirmed, the U.S. will have very clearly shown that it is in rapid decline. It will have shown that the government is corrupt to its core and is irredeemable.

    I work at a university. When hiring, if someone doesn’t have one of the “Required Job Qualifications”, they are immediately disqualified. We can wiggle a little if we can infer one of the qualifications from other experience, but that is pretty frowned upon.

    If we have things that we’d like to have but are not required, they are listed as “Preferred Job Qualifications”. We then create a rating scale for each based on their relative importance and grade candidates one each of the preferred qualifications. We use the resulting rankings to determine who we will interview. We MUST interview every candidate above the lowest ranked candidate we interview.

    I don’t understand why they don’t have a sign at the entrance to security to tell you what to expect. Or, when it changes by which line you go to, why they don’t have a sign indicating the differences between lines.

    Instead, they wait for someone to make a mistake, then yell out their mistake like “ALL ELECTRONICS MUST COME OUT OF YOUR BAG” at the same time as someone the next line over is yelling “ELECTRONICS DO NOT NEED TO COME OUT OF YIUR BAGS”.

    TSA is infuriatingky inconsistent and incomprehensible, even for someone who travels frequently.


  • I don’t say any of this to say that I think what Walmart is doing here is ethical, onky to say that it is logical from their standpoint if they assume there won’t be any blowback.

    Companies charge what they think they can get for a product. The tax is part of the price. If they think an item will sell for $5.26 including tax, it is reasonable for them to think it will still sell for $5.26 if the item isn’t taxed.

    That isn’t to say this is nice on their part, but the current system doesn’t incentivise them to be nice. It incentivises profit.

    It does seem like they took the easy route to gain more profit. It is likely that, in the a absence of tax, their profit would be maximized by a price that is somewhere between the old pre-tax price and the old post-tax price.
