The truth is there is no true "evidence" to suggest that we are the main, or even a majority contributing cause of global warming. All the facts that supposedly prove global warming are either circumstantial or entirely made up. Anyone here who is a older may remember the ICE AGE that we're supposed to be in right now? or Y2K when the world was going to explode. Global Warming is nothing more than that. Its propaganda used to elect presidents and convince you to buy different products. But here are some facts to support my opinions. 1. Co2 levels have been higher than they are now (dinosaur era) while life has continued to thrive. 2. Rise in C02 levels follows temperature rises by a good 800 years. 3. Google the 1500 year cycle. 4. Global Warming is occurring, at the same time on many planets (Jupiter, Saturn, Pluto, Mars, Triton[Moon]) which has lead many scientists to believe that Global Warming may be caused by the sun. there are other facts and I will reference them as necessary *Puts gigantic flame shield up*
Re: Global Warming: The Truth Isn't it that after a period of Global Warming, a period of Ice Age comes about? Whatever, I won't be alive that long, anyway.
Re: Global Warming: The Truth This should explain everything... [youtube]http://youtube.com/watch?v=yUwVqL1xtVs[/youtube] He's being serious... And I think that we are rising the CO2 slightly, but not so fast as to completely change our path.
Re: Global Warming: The Truth All that conservative talk radio you're listening to will rot your brain, kid. The real fact of the matter at hand is that we are killing ourselves, whether it be from global warming or the poison that we put into the toys kids play with or the cheap products that go into the food we shove into our fat, diabetic mouths. Oh yeah, the same sources you reference are the same ones that predicted we'd all be flying around in Jetson-mobiles by the year 2000.
Re: Global Warming: The Truth 2. temperature levels may/may not follow CO2 by 800 years, but thats not the issue. Snowball effect. CO2 warms the globe enough to start some minor melting, the dark blue oceans then absorb light. The warming would cause more ice to melt and more dark patches of oceans to appear. The once the ice caps melt Methane begins to be released from the oceans causing further warming. However, man made global warming isn't prevalent enough to cause this snowballing effect. In 12,000 years the ice caps will reach their former state and extend to the Southern U.S. Man made global warming can only delay the inevitable by a few hundred years. 3. Essentially answered in 2. 4. Solar scientists have noticed that sun spots can increase temperatures, but the arguement isn't that sun spots aren't causing that. The arguement is that they are not causing that right now. The sun spots aren't prevalent enough to make a large difference. I believe that man made global warming is REAL to an extent. If at any point you are putting a gas into the atmosphere that is known to increase temperatures, shouldn't it be increasing temperatures? Probably by fractions of a degree. So yes. I do believe global warming, I don't believe it really makes that much of an impact on us.
Re: Global Warming: The Truth Excuse me for not quoting I didn't say that man had no effect, I said that it was inconsequential, that Global Warming was a cycle. ironically if we did cut back on fossil fuels it may be worse than the Global Warming scenario we have now. read about this Here
Re: Global Warming: The Truth The "STOP" theory on there is really stupid. (It's the only one I read) Of course are Universe is going to be fine tuned. We wouldn't live on it any other way. Eventually there is going to be a point where the Universe after hundreds of gazillion years that everything would come together by coincidence to create a place livable for life.
Re: Global Warming: The Truth IDC about your flame shield, as a scientist I take your points but to say there is no evidence of human-mediated global warming is profoundly wrong and irresponsible. Your mention of a supposed ice age and Y2K have no bearing whatsoever on the issue and are presumably used here as spin to bias the reader in your own argument's favour. Firstly, it is a capital O. CO2 levels during the Cretaceous were four times current CO2 levels, and the global mean temperature during the Cretaceous was 11.2°F warmer than at present. [Barron, E.J., Fawcett, P.J., Peterson, W.H., Pollard, D., and Thompson, S.L., 1995, A "simulation" of mid-Cretaceous climate: Paleoceanography, v. 10, no. 5, p. 953-962] Dinosaurs and plant life had a considerable amount of time to adapt and evolve to changes in CO2 levels - c. 10 million years which saw an increase to 1000ppm in atmospheric CO2. Conversely, the current rate of increase in CO2 levels is considerably more rapid, at almost 4000 times this rate given the increase of 80ppm since pre-industrial revolution. Consequently life would have a vastly decreased chance of adapting to these atmospheric changes and I can give examples if you wish. It is correct that CO2 levels lag increases in temperature, due to decreased solubility of the oceans during warmer months. It is also correct that increased CO2 absorbs reflected radiation from the Earth's surface in the infrared and reflects it back, exacerbating the temperature increases and creating a feedback loop. It is also correct that we are releasing more and more CO2 into the atmosphere and that the ability of the ocean to absorb CO2 is decreased in recent years. Again I can provide the relevant data if you desire it. You are referring to Dansgaard-Oeschger events, which have not been observed during the Holocene epoch (which began ~ 11,500 years ago). The shocking lack of peer review amongst this group and it's alleged supporters of the claim that global warming is not happening and at the same time say that global warming will be a good thing is highly contentious and largely given widespread contempt. (During the Cretaceous precipitation was 23% higher and temperatures considerably greater than they are now). The co-authors wrote and published a book rather than a paper which, really, tells you everything you need to know. Were you to quote them back to me it would be ironically self-perpetuating. Of course global warming is caused by the sun. The Intergovernmental Panel on Climate Change incorporates the waxing and waning of Sol's output into its climate models and yet recently published its latest report which made several key statements: Additionally, most of the output from sunspots - which are the basis of your claim of cyclic warming due to Sol is in the visible range of the electromagnetic spectrum and as such of considerably less impact than you are being led to believe. The difference between the highest and lowest output due to sunspots is equivalent to <1% of Sol's total energy output.
Re: Global Warming: The Truth Holy crap, epic rape. But Ferretness, titling a topic, "..., The Truth." Is just food for the fire.
Re: Global Warming: The Truth Arnt we still in the ere during the end of an ice age / beginning of a new one. Meaning the ice caps are meant to melt.
Re: Global Warming: The Truth wow, Shock, your like hella smart. as long as it doesnt get tooo hot, im ok. Id rather much be living in an Ice Age than on a hot planet. I also read somewhere another theory that Global Warming is being caused due to the sun pulling the planets closer to it every year, who knows, in a few thousand years mercury and venus will have been gobled up by the sun and Earth would be right at the sun's doorstep...
Re: Global Warming: The Truth then we all die. wtf? haha. i just recently read/heard something along the lines of, that the water levels are kinda normal now. is a good sign...?
Re: Global Warming: The Truth Earth will be consumed by the Sun in approx. 7.8 billion years. However, current predictions claim life will be unsustainable in approx. 900 million years.
Re: Global Warming: The Truth 900 million is a little long. No species has survived past 900 million, I doubt humans will either.
Re: Global Warming: The Truth Shock. Why are you here you should be building lasers in some underground lab, not making forge maps. What about the moon hitting earth? In the same way that the sun would hit earth, because we are actually falling towards the sun, and missing, it. Well thats the way i was tought to understand it.
Re: Global Warming: The Truth The moon is getting further away from earth not closer. The moon was formed early in the Earth's life. The moon is a gigantic piece of the earth that was thrown off when two planetoids collided in the early solar system. The moon is too large for the earth to hold, so it will gradually break earth's grasp and drift - physicists decided this after evidence showed that the earth is far too small to capture a moon of that size. Big deal, why do we need a moon? Well besides from moon lit walks it also holds the Earth in its tilt. When it goes, so do our seasons. One week will be winter, the next it will be summer. One day your on the equator the next your near the poles. We are not 'falling' towards the sun. Imagine gravity as a fabric. When you put a rock on this fabric it makes a concave shape. If you put a marble near the shape it will fall into the rock. Why doesn't this happen in space? Universal Expansion. The idea is that after the Big Bang the universe began expanding and is continually expanding - even today. Eventually we will be ripped apart by this expansion, but for now it keeps planets steadily locked in their orbits. According to current theory. Some astrophysicists believe that we 'screwed up' gravity, in that model of the universe don't work unless we inject dark energy - dark energy does not exist it is a scientific term for 'we don't know' some say we got gravity wrong, some say we can't see dark energy. Whoever taught you had the right idea, but it's flawed. We are falling into the sun at the same time we are being pulled away by the universe.
Re: Global Warming: The Truth I was taught that all objects have thier own gravity. The more mass the object has the larger its force, and therefore we are attracted to the largest object, and smaller objects would be attraced to us. Something like that. Im doing GCSE, and we have finished physics and the exam, so im meant to forget it all. I could be wrong, that was the way i was tought and it was probably made simpler so it would be easier to understand. Please tell me how it really works if that isnt, im taking Physics in A level, and probably going further with it.
Re: Global Warming: The Truth Fair enough. And yeah i think that Global Warming is all a ploy. The newspapers make more, the oil companies make more, the government makes more. The tax payer pays more. Its just because now we have the technology to monitor the changes we make, that we realise that our changes are out of control? BS.
