  1. Re:Wrong Science on Human Water Use Accounts For 42% of Recent Sea Level Rise · · Score: 1

    Well, we are doing a lot more than drinking and pissing, don't we? We irrigate, we pump ground water etc.

    Let me try a simple model. It's not a working model, but it shows on a very simple scale how things are interconnected:

    Let A,G,O,S be the amount of atmospheric, ground, oceanic and surface water.

    Now, we can assume that the rate of change for each is at least partially dependent on its amount. We can thus formulate differential equations.

    For example, surface water gets replenished by precipitation and by groundwater seeping out from natural wells. Therefore

    dS/dt = k(AS)*A+k(GS)*G

    k(AS) and k(GS) being first order rate constants for transfer of atmospheric and ground water to the surface, respectively.

    That's not all of course, surface water is also lost to the other reservoirs. So:

    dS/dt = k(AS)*A+k(GS)*G+k(SA)*s+k(SG)*S+k(SO)*S

    Nomenclature for the other rate constants as above. Now, we can do this for A,G and O the same way and get a system of differential equations, which in reality, are of course not strictly first order and not strictly dependent on the simple amounts, but lots of other factors.

    Since we are playing with the rate constants, in particular related to evaporation and ground water extraction, we get measurable changes in A,G,O and S.

    Simplified, but voila, Science.

    As long as the rate stays constant. Given the current sea ice data, I do have my doubts about that, though.

  3. Re:Really? on Human Water Use Accounts For 42% of Recent Sea Level Rise · · Score: 2

    Oh that I live to see this day, I agree with tmosley. Well played. That's basically the process, as far as I know - we extract loads of ground water - fresh one as well as fossil one. So sinks for water, particularly deep aquifers, play a lesser role in the water cycle. Since we force water to stay near the surface, evaporation increases and transport to the sea becomes increasingly important compared to transport into ground water. How, in the long term, ocean evaporation rates may change to counteract this is another problem, one for which I do not know any studies out of hand.

    Pretty much that. I grew up close to the Czech border in Germany. Wasn't that much of a fun place in the 80s. Our history teacher was military reserve - he used to tell the occasional story about how they nuked our hometown during the last training exercise. Roads were prepared with access shafts to place explosives to destroy the infrastructure, should the Soviets decide to move, lots of fun stuff like that.

    I'd like to see the details of that calculation, but I fear that you are off by a couple of orders of magnitude somewhere. The thing that makes Yellowstone so dangerous is the fact that the mantle plume melts the granitic crust, yielding a highly volatile, gaseous granitic magma. I doubt it that the energy to melt the crust over the whole Yellowstone area concentrated into Lake Yellowstone just turns out as 10-20 times the solar constant, area-wise. That's not to say that geoengineering on such a scale is impossible as such, though.

    Also, more people should read Glen Cook, btw.

    Coming from Germany with its huge culture around sourdough bread I was shocked when I shopped for bread in a Californian supermarket for the first time. It was late already, I just came from the airport and I just wanted to grab something to make a sandwich. When I unpacked the stuff and took the first bite, it was... just horrible. When I studied the packaging, I learned that they obviously added a metric fuckton of molasses to the bread. What... the...??? The stuff was sweeter than some of the cakes I was used to.

    Here we are closing in on the problem. McDonalds food is indeed perceived as tasty by a lot of people. If you know anything about food, if you tasted actually decent food before, you will of course recognize it as the bland boring crap it is. Many people, however, do not have that knowledge or experience. If you watch the relevant Jamie Oliver shows, like Food Revolution or Ministry of Food, you get the impression that we are rapidly losing our cultural knowledge about food and cooking as an everyday experience.
