Warming and Slowing the World

chrisleonard writes "We all know that global warming is supposed to heat the planet up, but did you know that it might also slow it down? According to a report from Belgium's Royal Observatory (as reported here by astronomy.com), if the days seem a little longer to you than they used to, it might not be just old age catching up with you. Would it be wrong to call the interaction of the world's warming temperatures and its slowing rotation ... a snowball effect?"

      Good god. It doesn't work that way.
      The equatorial circumference of the earth is 40,000 kilometers.
      Given that the earth rotates with a period of 24*3600 seconds, give or take a few, the velocity of a person on the equator is 40,000,000=v86,400 or 462 m/s.
      Centripetal force is F=(mv^2)/r. The equatorial radius of the earth is 6,400km or so. Thus, a 100 kg person at the equator experiences F=(150*462^2)/6,400,000=5 newtons of centripetal force. One kg is 9.8 newtons. Thus, centripetal force has next to no effect on your perceived weight today.

      Now. Assume that a subtraction of 2m/s of acceleration from the downward gravity induced Fw is significant. Centripetal acceleration is v^2/r. 2=v^2/6,400,000 v=3600. V would have to be 3600m/s for a significant counter to gravitational force. Note that this is 9 times the current value, so the earth's day would have to be less than 3 hours long. I don't think that's very bloody likely.

      Yes, I know that centripetal force is actually an inward force and isn't applicable in this situation. But the magnitude of centripetal force is equivalent to the magnitude of centrifugal force, which I didn't use because it doesn't actually exist. At any rate, it all works out. Trust me.

They of course did say that chopping down unexplored rain forests could very likely wipe out plant and animal life that had never been recorded. Of course that's no deforestation.

The geologists were stumped on that one until an artic diver happened to notice something under the ice in one of his dives. He found a plethora of life below the ice in the form of green algae and a few other things that I can't think of the words for. He said there was at least 30 meters of ice above him. He said there was a great deal of bright light coming down through the ice. He knew why also. If you quickly freeze ice, air will get trapped inside and form the white spots you see in ice cubes. If you cool it slowly though, the ice will freeze from the bottom up and will not contain air pockets (many anyways) making it extremely transparent. He proved the theory. Whew, enough typing.

    I'm sorry, but I'm going to pipe up here.

    If you're basing "global warming" off anecdotal evidence, Canberra in Australia (where I live) has just had one of the coolest summers ever. The opposite of your experience. And please, don't try that b-s line on me that "global warming makes the extremes greater", because that's not global warming.

    But allow me to present the case against the global warming phenomenon.
    1. The temperature that is used by most scientists to prove the world is "warming up" is taken at posts that have been established for circa 100 years. Any further back than that there's no guarantee that the information is accurate. As a result of scientists normally living in larger cities as opposed to country towns, most of those weather posts were set up beyond the outskirts of large towns/cities approximately one hundred years ago.

    However, as is the nature of these cities, they have grown/sprawled to encompass these weather posts. Now, as any scientist can tell you, cities are warmer than their surrounding regions. It's known as the "urban heat island effect". Tarmac, cement and all those other human building materials absorb and retain a much greater proportion of the heat that hits them during the day than does undeveloped land. Try walking over bitumen during a hot day and then walk over dirt. You'll see what I mean.

    As these hotter cities expand to encompass the temperature stations, the temperature recorded by them is artificially increased. However, it's an extremely localised effect - the city is warmer, yes, but there's no way that the city is warm enough to have any effect on the surrounding countryside. It doesn't warm the globe up.

    So, to begin with, almost all the statistics the global warming proponents are chucking round are incorrect.

    2. Furthermore, land covers only 1/3 of the earth's surface. The other 2/3 is the ocean. Funnily enough, scientists haven't measured the temperature of the ocean over the past 100 years - there are generally only temperature stations located on the land. So the statistics that I've outlined above, that I believe already are flawed, are no greater than 30% of the surface area of the planet.

    3. NASA satellites (which have been measuring the temperature of one of the atmospheres of the planet - I forget it's name, but it's about 1km above the surface of the planet) shows that the planet has actually been cooling down since the records have recorded. How is it that the planet has been warming up yet the atmosphere cooling down? And remember, these statistics are taken for the entire planet, not just the area over which is land.

    4. From core samples that have been taken in various places over the planet, scientists have been able to determine both carbon dioxide and temperature levels. They've graphed both these over hundreds of thousands to millions of years, and guess what it showed - carbon dioxide moves as a result of temperature, as opposed to vice versa.

    5. Another scientific experiment that's very interesting - in an isolated greenhouse, increase the proportion of carbon dioxide in the atmosphere. Guess what you'll find? That the trees/plants grow faster. And as such, increase their intake of carbon dioxide, and produce more oxygen!

    As such, my opinion is that the effort that is spent worried about global warming should instead be re-directed towards the preservation of native habitats, especially old growth forests which are our greatest ally as carbon dioxide recyclers. They are, quite literally, the lungs of our planet.

As several people have pointed out, it is absurd to assume the questionable names were added by the petition's authors; they were obviously added by critics wishing to discredit the petition, and have subseequently been removed.

      This no more makes it certain that it is a hoax than the objections raised by some of the IPCC authors to that report's contents (which, they asserted at the time, were forced on them by the lead authors for political reasons) make that report a hoax. Such accusations can (and have been) made by both sides. That's part of what makes it a controversy.

      In any case, questions of science can not be resolved by pettition. In this case, we may even be past the point where data will help, since the sides seem to be polarized beyond even agreement on terms.

      For example, over what time period are we talking? It is quite posible to have a warming trend on one scale and a cooling trend on another (think about a fall morning; between, say, dawn and noon, the temperature is likely rising, but that doesn't mean winter has been cancled). Are we talking about the upper atmosphere, the lower, or maybe the sea surface? If we are talking about the earth as a whole it is clearly cooling, since the bulk of the heat is in the molten iron core. But I doubt most people mean (or even consider) that.

      All of this, without even touching on questions like "are people causing this?" or "is one side or the other using the issue as a cloak for some political agenda?" or "what should/can we do about it?". It is a complex issue, or at least seems so to an "absolute idiot" such as myself.

      It was the hope that Discovery was doing more than presenting just the standard knee-jerk "the sky is falling" line that raised my estimation of their credibility.

If we get off of our butts and tap the oil in the Gulf of Mexico, we could be self sustaining and not need oil from saudi. This is a fact (wish I could atrribute a source but it's late and I am going to bed after this). Here's an interesting link about ANWR. The reasons these ecological wackos have come up make no sense and have no scientific backing except some crap some scientists who liked the idea has drawn up.

Hydrogen and fuel cells hold great promise not just from an environmental sense, but from a business sense as well. Imagine if we all had a fuel cell on our house. We'd no longer be dependent on wires going underground and into our house and no longer would we have to worry about lightening striking the above ground wiring because there would be none. When ever Hydrogen is cheap (it's cheap now...), you'd just fill it up and be good to go. The waste water created by the reaction could be ran through a filter, and used to flush toilets or take showers or heck even drink. Who WOULDN'T want this? Even the big oil would want a piece of this. The good thing is if we actually tap the Gulf adequately, we could be assured we would have enough oil until this stuff is perfected. Right now, if we decided to bomb someone in the middle east, we may as well grab ahold of a bank loan to buy gas cuz it's going to go up. My biggest point here, is that it doesn't have to be this way. it's only this way becase a small MINORITY thinks the sky is falling when it's not.

    After seeing loads of pseudo-science (on both sides), I took the time several months ago to look at the scientific literature and try to learn about the validity of claims that many laypeople made about global warming. The parent touched on a few of these, and I couldn't resist digging in...

    1) Global temperature is decreasing.

    No. Even the most cursory look into the subject should show this to be false. For an example, check out the graph on this page. Almost all of the literature I have read agrees on this. The debate comes in when you start talking about how much/why/is this natural?

    2) The atmosphere already contains carbon dioxide and needs it in order to keep the Earth warm. Thus, more carbon dioxide is not bad.

    While the atmosphere does contain significant amounts of CO2, the thing to remember is that it needs to maintain a balance. As an analogy, think of your body. If you don't have enough iron, you get sick (e.g. anemia). If you have too much iron, you also get sick.
    One of the biggest sources of natural atmospheric CO2 is plant matter. At the end of the 19th century, human CO2 emissions were comparable to global plant matter emissions (~150 MMt). By the end of the 20th century, human emissions were 40 times greater than the plant CO2 emissions. You can check this up at the CDIAC site.

    3) Global temperature increases can be explained by volcanic emissions.

    Also not the case. In fact, one of the landmark papers (Mass, Portman 1989) actually showed that the net effect of each of the several largest 20th century volcanic eruptions was a decrease in global temperature. The reason for this is that, while volcanos do put significant amounts of CO2 into the atmosphere, they also release substantial quantities of particulate matter (e.g. ash). The effect of the latter is to decrease the net amount of sunlight reaching the Earth's surface.

    4) Global warming can be explained via sun spots, orbit variations (Earth and/or lunar), etc.

    I was unable to find very much evidence of this in the literature. I was, however, able to find a significant amount of "pop sci" articles supporting these theories.

    The general consensus is that scientists do not know enough to fully evaluate the problem, but that humans do have a measurable effect on the atmosphere. The scientific side of the debate centers around the size of this effect, and whether or not it is significant. The atmosphere is incredibly complex, and we may never be able to fully describe it. To me, this appears to be as good an argument in favor of reducing emissions as any other.

    On a side note, I found the following to be generally true of articles/papers about global warming: The "seriousness" and scientific legitimacy of such an article are inversely proportional to the concreteness of the claims. Papers claiming that "global warming is just a myth", that "global warming can be explained by some never-before-heard theory", or that "global warming is already upon us and will put most of the Earth's land underwater in the next few years" almost never appear in peer-reviewed scientific journals, while papers claiming that "we really don't know enough yet to make firm conclusions" almost never appear in pop sci magazines.

The only reason we have the atmosphere we do (almost no carbon, lots of oxygen) even though we started out with a carbon-heavy atmosphere is that the plants sucked down every scrap they could get their grubby little leaves on. As one on my professors put it, "dumping CO2 into the attmosphere is like throwing money off a building in New York City: you might change the local environment some, but if you expect it to accumulate and block up the street, you're dreaming." In the 1960s, the more vocal global warming advocates were asserting that, by 2000, the earth would be uninhabitalbly hot. They keep shifting the claims, but it always amounts to "dire things will happen ~40 years from now unless you do what we say now, without wasting time on study or debate." This has biased me against them. The people I have personally met who have felt most strongly about global warming seem to 1) fear and resent "technology", and 2) have a burning desire to believe that what they do makes a difference in the big picture. This is pretty easy to test if you bait them with "I heard about an article that may have claimed..." and see which silly statements they will accept & which ones they reject. It's my conclusion that the reason the "people are changing the Earth's climate" story sells so well (along with nonsense like "cut the plastic tabs on your six packs to save the dolphins") has much more to do with a fear of insignificance and a need for "redemtion" than with anything rational. And yes, I do see the analogy with my quick acceptence of the pettition, despite the fact that I don't trust "Discovery" and I don't trust "Science-by-pettition"--I suspect I am swayed by my pro-technology/on-the-galactic-scale-humans-are-in significant bias.

      Rather than typing in material from my old text books, I did a quick search for similar text on the web (risky, I know, since some of the sites I cite might turn out to be funded by Republicans (*smile*)):

      Most of our conventional crops, including rice and wheat, assimilate atmospheric CO2 by the C3 pathway of photosynthesis, which takes place in the mesophyll cells of leaves. Photosynthetically, these plants are underachievers because, on the one hand, they assimilate atmospheric CO2 into sugars but, on the other hand, part of the potential for sugar production is lost by respiration in daylight, releasing CO2 into the atmosphere, a wasteful process termed photorespiration. This is due to the dual function of the key photosynthetic enzyme, ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco). High CO2 favors the carboxylase reaction and thus net photosynthesis; whereas high O2 promotes the oxygenase reaction leading to photorespiration. When plants first evolved, photorespiration was not a problem because the atmosphere then was high in CO2 and low in O2. As a byproduct of photosynthesis, O2 accumulated in the atmosphere and reached the present level a million years ago. Current atmospheric CO2 levels limit photosynthesis in C3 plants. Furthermore, photorespiration reduces net carbon gain and productivity of C3 plants by as much as 40%. This renders C3 plants less competitive in certain environments. In contrast, with some modifications in leaf anatomy, some tropical species (e.g., maize and sugarcane) have evolved a biochemical "CO2 pump," the C4 pathway of photosynthesis, to concentrate atmospheric CO2 in the leaf and thus overcome photorespiration. Therefore, C4 plants exhibit many desirable agronomic traits: high rate of photosynthesis, fast growth, and high efficiency in water and mineral use.

      ...and:

      CO2 enrichment can also affect plant communities directly. For many plant species, increased CO2 concentrations lead to increased rates of net photosynthesis and improved water-use efficiency, resulting in larger plants. This effect is greatest in C3 plants and is typically small or negligible in C4 plants. Where plant communities consist of both C3 and C4 species, the different responses of these two groups can lead to changes in plant community composition over time.

      Finally, IIRC, most of the biomass is C3 plants.

      The Oregon Institute's "petition" is a hoax. The names are largely made-up. I recall Captain Kangeroo being among their number.

      The names weren't "largely made up". Rather, once the petition started collecting enough names of real scientists that it was worth taking notice of, environmental activists trying to discredit the petition deliberately submitted a few phony names which have since been removed. According to this source:

      When the Oregon Petition first circulated, in fact, environmental activists successfully added the names of several fictional characters and celebrities to the list, including John Grisham, Michael J. Fox, Drs. Frank Burns, B. J. Honeycutt, and Benjamin Pierce (from the TV show M*A*S*H), an individual by the name of "Dr. Red Wine," and Geraldine Halliwell, formerly known as pop singer Ginger Spice of the Spice Girls. Halliwell's field of scientific specialization was listed as "biology." (emphasis added)

      It is pretty unlikely that the funny names were put there by people who favored the petition.

    I find it hard to believe that you studied botany.

    The fact that you disagree with me isn't a very good basis on which to doubt my statement that I studied botany. I may, for example, have had rotten teachers, or it may have been a long time ago, or I may have been an awful student. Or, for that matter you might be wrong. As it turns out, I was a botany major for three years, it was a long time ago, and I'm probably not an impartial judge on the other questions.

    If CO2 were a limiting factor, it would be in short demand, but it's in great excess...is very readily available at the elevations in the atmosphere where it's required.

    I suspect you mean "great demand" or "short supply" (instead of "short demand"). CO2 is not abundant. It makes up less than 0.04 percent of the atmosphere (Argon, for comparison, is 25 times as common, but you don't hear people talking about Argon as particularly abundant).

    N and P on the other hand, are in demand, and usually not in great surplus.

    IIRC, this is quite true in areas with exceptionally high water flow (e.g. rain forests, the open sea), since fixed Nitrogen & Phosphorous are generally very soluble, and thus wash away. But most plant growth occurs outside these areas (this is why people are so concerned about the rain forests; they grow very slowly and will take a long time to recover).

    Plant matter (dried) is about 45-50% carbon & 40% oxygen by mass. Less than 0.5% is nitrogen & phosphorous (combined). Plants are mostly starch / sugar / cellulose--in short, carbohydrates--and very little protein (which is where the N & P go). So the C/(N+P)ratio in plants is on the order of 100 to 1.

    If you look at the volume of space surrounding a plant (say, half air, half soil) you will see fixed nitrogen in the soil between 10 & 50 ppm. Given dirt's specific gravity is around 2.5, and air's is around 0.00127, and therefore dirt is pretty close to 2000 times as dense as air, and carbon is just a little lighter than oxygen, we find an environmental ratio of about: (0.03%/3) to (2000*50/1000000) or 10^-5 to 1.

    Thus, from a plants point of view (comparing abundance inside the plant to outside the plant) nitrogen and phosphorous are about 10^7 times as abundant as carbon.

    The idea that CO2 is a limiting factor for most ecosystems is laughable.

    *smile* You say that, but I'll bet you wouldn't cough up a "+1 Funny" if you had mod points, would you?

    Structures require what is known as maintenance. Sometimes they are even scrapped due to age. The "global warming", if it is in fact happening, is happening so slowly that normal maintenance and abandonment will take care of it.

    Was it New York that had to spend billions a year of very real $$$ on aerial spraying when a disease-spreading mosquito was able to establish itself there?
    Whatever, if the climate changed, the reach of maleria for example would also change, and (most likely) enlarge. Possibly greatly. While the reverse (decrease maleria) is a far more remote possibility. Maintenance just isn't relevant. The costs in money and human life and misery would be very real. Sure, we're dealing in probabilies, but that's no excuse for ignoring well-established successful methods of risk management.

    If it turns out that global warming is happening but that the major causes are natural, then we're still better off if we've done everything we can to stop making things worse.

    No, we aren't. In that case it's been a monumental waste of effort
