The layers would be concentric spheres around the Earth, obviously.
The point is that the relative concentration of CO2 with regards to nitrogen/oxygen is irrelevant. The crucial factor is the absolute amount of CO2 that the IR radiation has to travel between surface of the Earth and outer space.
And that absolute amount of CO2 has been increased by about 35% in modern times.
I don't expect you to understand this. This post is meant for other people.
Second, potentially, it could be made safe, but only by raising costs
Money is not the issue. Late fuel loading increases rocket performance.
The refrigeration doesn't have to be internal
What are you talking about ? There's no refrigeration.
Fourth, we know from the launch of the car that the guidance systems and engine control are flaky.
How is the guidance system software relevant for the fuel loading procedure ? The explosion happened because the designers didn't completely anticipate all the physical interactions between the oxygen and the carbon wrapped pressure vessel. Once you do understand these systems, the software is the easy part.
The composition of the atmosphere has been changed a fraction of a tenth of a percent.
Imagine we separate the atmosphere in different layers of pure gases. The pre-industrial amount of CO2 would then be equivalent to about 3 feet thick layer of pure CO2. The current layer of CO2 would be about 4 feet.
The fact that this layer of CO2 is very thin compared to the much bigger amounts of nitrogen and oxygen is irrelevant. Nitrogen and oxygen don't block IR.
People with darker skin and/or living at more extreme latitudes cannot form ample supply. Also people spend more time indoors, and use sunscreen because of all the skin cancer scares.
Trees are very inefficient. Photosynthesis only captures a few percent of the Sun's energy. Trees also require space, decent soil, and water, so they compete with agriculture. And unless you bury the trees, that carbon will be released again.
Mineral capture could be used in deserts and other useless areas.
Trans fat is considered by many doctors to be the worst type of fat you can eat
Agreed, but this in the context of industrial trans fats, which were causing health problems. It says nothing about ruminant trans fats (mostly vaccenic acid) in particular.
Simple question: if ruminant trans fats are bad, why does mother nature give them to the calf ?
Probably because gamma radiation treatment is never discussed in the media, so they don't realize it's happening ? I must admit I had never heard of it until now.
We're not going to be able to feed the planet if we don't embrace GMO
Even with GMO, you're not going to be able to feed exponentially growing population indefinitely. At some point in time you're going to hit the limits, and the higher the limits are, the more people will suffer.
Two glasses of milk have the same trans fat of a salad made with soya oil.
The same amount of total trans fats, or the exact same trans fatty acids ? There are good reasons to assume that the particular trans fatty acids in milk are harmless.
As gene editing results in different food items we put in our bodies ("healthier soybean oil") there's a good argument against its usage: we have insufficient long term knowledge about the consequences of these new compositions.
Trans fats are a good example of what can happen if you introduce new kinds of substances without proper testing. And proper testing is almost impossible to do for dietary items.
I want to sell stock. You want to buy stock. I set a sell price of, say, $1, while you set a buy price of $2. HFT sees both of us before we see each other, buys my stock for $1, sells it to you for $2, and pockets the difference.
That's not how it works. As soon as a matching order appears for one that's already in the order book, a trade is made between the two parties at the price of the first order, without any possibility for a 3rd trader to get between them.
FPGAs can run circles around GPUs as well, given the scope of execution needed
You have no idea what you're talking about. NN evaluation requires multiplications, big caches and fast external memory access. FPGAs are lousy for all of those things. Big FPGAs are crazy expensive too. And their key property, the ability to upgrade them in the field, is totally useless for this application.
I wouldn't take a bet that there won't be big changes in the near future.
Most likely, the silicon can handle future changes just as well as current graphics cards, if not better. Also, I would expect Tesla to keep evolving their hardware.
The cars themselves don't learn, but that would be very inefficient anyway. Tesla can review accident logs, modify their NN, and then send updates to all the cars.
FPGA technology makes no sense. FPGAs are slow and power hungry for NN applications. Besides, there's no reason to change the hardware. The same silicon can implement a wide variety of neural net topologies and weights.
First, you have to QA the silicon in all of the ambient environments, which means the worst of Alaska to the heat of Death Valley, all precip, all RF/EMI, etc.
Sure, but that's routine part of the design. Every modern device has several pieces of silicon that went through that process. There are tools and people that know how to do this.
Then using a closed OS (or a modified BSD-licensed RTOS), you have to ensure its reliability and recoverability from miscellaneous events. Then you have to train the sucker.
Which has nothing to do with proprietary nature of the silicon. Even if they had bought standard silicon, they'd still have this problem.

Hard to argue with them when they constantly re-adjust data to fit theories
We are having heat waves because scientists tampered with our thermometers ?

No, but if you change the climate, you change the weather.

Maybe you can lead the way. Switch off your computer and never turn it on again
You can't solve the Tragedy of the Commons by personal actions.
"Microplastics" are the nanometer grade particulates
No. Microplastics are sub-5mm pieces. The ones you're talking about are called "nanoplastics"
We need to get to the levels of Denmark and Finland
Actually, we need to get to zero emissions, otherwise the problem will continue to get worse.
And we'll see more and more places with humid 30+ C.
Since the CO2 effect is cumulative, a fair comparison would take into account past emissions as well as current ones.
The plastic polymer may be inert, but that does not apply to the additives that are mixed in with it.

There's no guarantee that off-the-shelf hardware from NVidia is a better match for networks 10 years from now.
