    I personally think that Global Warming being caused by mankind (rather then the earth's cycles) has been blown out of proportion. HOWEVER, what does it hurt to take better care of the earth???

    One case in point is the auto industry. The big three didn't do a dam thing until the Federal government passed new laws. They should be updated and even other areas should be covered.

    The Sun.......What a crazy idea!

    The truth about global warming - it's the Sun that's to blame

    Global warming has finally been explained: the Earth is getting hotter because the Sun is burning more brightly than at any time during the past 1,000 years, according to new research.

    A study by Swiss and German scientists suggests that increasing radiation from the sun is responsible for recent global climate changes.

    Dr Sami Solanki, the director of the renowned Max Planck Institute for Solar System Research in Gottingen, Germany, who led the research, said: "The Sun has been at its strongest over the past 60 years and may now be affecting global temperatures.

    "The Sun is in a changed state. It is brighter than it was a few hundred years ago and this brightening started relatively recently - in the last 100 to 150 years."

    http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2004/07/18/wsun18.xml&sSheet=/news/2004/07/18/ixnewstop.html

    ALSO.......

    Sun Energy Output At Over 1,000 Year Peak

    Sami Solanki, Professor at the Federal Institute of Technology in Zurich Switzerland, says the Sun has been burning more brightly over the last 60 years than over the previous 1090 years.

    “We have to acknowledge that the Sun is in a changed state. It is brighter than it was a few hundred years ago, and this brightening started relatively recently – in the last 100 to 150 years. We expect it to have an impact on global warming,” he told swissinfo.

    The sun's brightness hasn't changed much over the last 20 years. But it has been brighter for the last 60 years than it has been at any time in the last 1,150 years.

    According to scientists, the Sun’s radiance has changed little during this period. But looking back over 1,150 years, Solanki found the Sun had never been as bright as in the past 60 years.

    The team studied sunspot data going back several hundred years. They found that a dearth of sunspots signalled a cold period - which could last up to 50 years - but that over the past century their numbers had increased as the Earth's climate grew steadily warmer. The scientists also compared data from ice samples collected during an expedition to Greenland in 1991. The most recent samples contained the lowest recorded levels of beryllium 10 for more than 1,000 years. Beryllium 10 is a particle created by cosmic rays that decreases in the Earth's atmosphere as the magnetic energy from the Sun increases. Scientists can currently trace beryllium 10 levels back 1,150 years.

    Sunspots have been increasing in number as the Earth has been getting warmer.

    Over the past few hundred years, there has been a steady increase in the numbers of sunspots, a trend that has accelerated in the past century, just at the time when the Earth has been getting warmer.

    Variations in sunspot activity are probably behind the increases and decreases in solar radiation and consequence changes in Earth's climate.

    During the Medieval maximum of 1000-1300 there was an extremely large Sunspot which is believed to have warmed the Earth higher than normal. There were no accurate measurements of the weather to call upon during this time but the discovery and colonization of Greenland by Eric the Red supports this hypothesis. Eric was exiled from Iceland for manslaughter and sailed west discovering Greenland. He then led many ships, filled with people who wanted to make a fresh start, to this new land. For 300 years Greenland flourished, new communities settled, trade with other countries grew, and the population increased. Around 1325 the climate cooled down considerably, people started to abandon the northern settlements. By 1350 glaciers covered the northern settlements, and the southern most settlements were dying out as well.

    The Sporer minimum of 1400-1510 and the Maunder minimum of 1645-1715 were each known as a "little ice age." They were both droughts in Sunspot activity, and a link to a time of abnormally cold weather on Earth. In addition to finishing off the Greenland colonies, the Sporer minimum showed increased rates of famine in the world, and the Baltic Sea froze solid in the winter of 1422-23. Some of the more notable effects of the Maunder minimum included the appearance of glaciers in the Alps advancing farther southward, the north sea froze, and in London there was the famous year without a summer where it remained cold for 21 consecutive months.

    The evidence supports the effect of Sunspot activity on the Earth's climate, but that is only one of many areas that effects us on Earth. On March 13,1989 a large Sunspot ignited powerful flares that tripped the circuit breakers a generator station. The started the collapse of the Quebec power system and left people without power for hours to days. These same flares damaged several man made satellites, and caused smaller outages all over the U.S and Canada. There are countless other times when large Sunspots have effected similar damage to various electrical systems on Earth.

    all the planets are heating up

    Does it matter? We don't have to live on other planets, just Earth. We all need to be concerned about our home and keeping it clean and livable.

    If you want to ignore or excuse the changes we see taking place, that's your prerogative. Maybe God is warming up the entire Universe....there's enough theories to pick one, so go ahead and humor yourself. In the meantime, don't take it personally if others decide to be proactive in trying to lower temps. Life is too precious to just wait (until it's too late) and see.

    Actually, I am not ignoring the changes that are taking place. I just think that the elevated solar radiation levels that are heating up all the planets plays a larger role in global warming than what man is doing. If you look at some of the links that are posted, some of the other planets are going through greater and more unusual storm periods. Now this is not to say that we can't do a better job in taking care of our planet but to try to lay all the blame on SUV's is stretching it a bit.

    Maybe God is warming up the entire Universe....there's enough theories to pick one, so go ahead and humor yourself.

    Elevated solar radiation levels and all the planets heating up is not a theory, it a fact. (try not to employ watchtower reasoning techniques, we left for that reason, remember?)

    We had snow here a few weeks ago and we are on the Pacific NW coastline.

    Check out my photo spread if you are interested in the beauty of snowy dune grass and snow meeting the ocean.

    The kids had fun but this has been one heck of a winter for us if you have watched the news this winter....we even had 2 hurricanes as far as the wind is concerned. Yikes!

    The sun causing global warming is another debatable reason. It seems there may be some influence, but it seems most scientists agree it's not THE reason.

    Exactly. Thats the position of the IPCC.The sun has been responsible for some warming from1900-1940. But since satellite measurements started in 1978 there has been no solar trend matching the rapid increase in temperature in that period. The stratosphere (thats the level above the troposhere) is actually cooling too. It would warm if the sun was increasing intensity.

    As to warming on Pluto. How far away is pluto. Nooooo! i dont think so.

    Warming on mars? One little portion of its southern ice cap shrinks and people can infer a global phenomenon on mars. If Scientists here on earth claimed there was global warming on the basis of one melting glacier theyd be laughed at. But anyway, we are measuring the sun and there has been no trend to match the temperature trend. Rule out the sun as primary cause.

    Who are you responding to? I mean, you quote me;

    Never before have billions of tons of stored CO2 been released into the atmosphere in such a short space of time.

    And what you say is;

    Actually our atmosphere is CO2 impoverished.

    Does this mean you have no comment on how billions of tons of stored CO2 have been released in such a short space of time?

    Your argument seems to be;

    In a time period where known forcing (orbit, solar variation, etc.) does not explain sudden average temperature rise, and masses of CO2 has been released by man (let alone agricultural inputs of greenhouse gasses), saying that in the past CO2 levels were higher means we can doubt the role of CO2 in the current temperature rise.

    Please let me know if I mis-state your case. If I am right, what were the forcings at those points? Where was the Earth in its orbital cycles? Where was the sun in its variation?

    If you want to make the argument I think you are making, you need to show that known forcings in those periods and the level of CO2 cannot explain the temperatures we believe were prevalent. Over to you.

    No one disagrees with the amplifying effect of CO2 in previous warmings when CO2 increase was not a primary cause of climate change. What this approach ignores is the fact in previous episodes CO2 was changing in response to climatic trends, not as a result of agriculture and fossil fuel use. So, we have whatever amplifying effect the levels of CO2 that would be here anyway PLUS those of the additional CO2.

    Of the 186 billion tons of CO2 that enter earth's atmosphere each year from all sources, only 6 billion tons are from human activity. Approximately 90 billion tons come from biologic activity in earth's oceans and another 90 billion tons from such sources as volcanoes and decaying land plants.

    It would seem you are confusing CO2 cycles with CO2 increase. No one disputes the large amounts of CO2 in cycles; they are called cycles because they cause no overall increase over time, at least not the 200 years we are actually discussing. Again, you go straight to a point which means you can avoid discussing the real issue, the extra CO2 in the atmosphere because of man, Human CO2 release is not a cycle! Your point is simply not relevant to the discussion, it is a red herring.

    I "beg" to differ :) The question of "how much" and "to what extent" CO2 affects the atmosphere is central to the issue.

    Yes, but if water vapour (which you bought up) is NOT changing (which means you bringing it up was another way to avoid the actual issue), and CO2 is, the effect of the extra CO2 is what is important, not the fact water vapour plays a larger role.

    You seem to think that because the absolute proportions of CO2 in the atmosphere have only changed a little, the effect cannot be important. That's like saying the level of a toxin in a system going from 3.3% to 3.6% isn't important as it's a tiny change, when at 3.5% the level of the toxin becomes high enough to cause damage. Or that the 2.3% active component of a pill is insignificant compared to the 97.7% of filler.

    Just as it was easy to get hornswoggled by those nice people tobacco companies employed to deny links between tobacco and cancer, due to their skillful dissembling, so to it is easy to get distracted by the disingenuous arguments by their modern-day equivalents, the climate change skeptics. There is no real big deal in being fooled by mislead or dishonest experts who are out to mislead you or fool you; they're "experts", after all, and it is easy for experts to pull the wool over the eyes of a lay-person. N.B.; If you're annoyed about this they are the people to be annoyed with...

    All of the arguments you have so far advanced do very well at distracting from the issue of man releasing masses of CO2 by making CO2's role seem unimportant; this does not change the fact that; I don't think you do this deliberately or out of evil intent, you have simply had a number worked on you by people who are very good at what they do; they try to distract people from the real evidence and issues of climate change with exactly the sort of points you've bought out (you've studied their arguments well).

    It really is simple, just like sucking burning leaves into your lungs being bad for you is very simple (it is worth recalling the example of the tobacco industry's disinformation and collusion again);

    1. There is far more CO2 in the atmosphere not due to cyclic processes or responses to general climatic trends but as a result of human activity.
    2. The increase in temperature that we have seen unrelated to any known forcing occurs at the same time as this increase in CO2 levels due to man.

    You seem to be stuck on the smoke and mirrors,

    OK, but I'm not following it... http://www.worldclimatereport.com/index.php/2006/12/01/are-humans-involved-in-global-

    LOL So these two guys claim that their adiabatic model of heat transfer in the atmosphere shows humans could heat the atmosphere by no more than 0.01°C.

    You're falling for it again; this is smoke and mirrors. No one serious is saying global warming is due to direct heating of the atmosphere (which is what that claim actually means).

    They also compare total anthropogenic carbon dioxide emission of 1.003 × 10~18 g with hypothesized total mass of CO2 degassed from the mantle of 4.63 × 10~23 g.

    This is used to declare that human CO2 release is only 0.00022% of the total CO2 amount naturally degassed from the mantle. Very impressive, and just the sort of claim climate change skeptics love.

    Do they also love these two guys are comparing 4.5 billion years with 200 years? Not really a fair comparison, but as you only get into the fairness of the comparison if you go PAST the smoke and mirrors... did you notice how they do not seem to consider how much of the 4.63 × 10~23 g CO2 released by outgassing is still in the atmosphere? Kind of sloppy considering this figure is 150,000 times the amount of CO2 than is currently in the atmosphere

    Total human-released CO2 of 1 x 10~18 g of CO2 in 200 years IS significant in light there is less than 3 × 10~18 g of CO2 in the atmosphere

    There are more faults in the paper;

    The paper of Khilyuk and Chilingar (2006) contains several more unconventional theories, e.g., the twice repeated hypothesis that in 0.6 Gyr “endogenic oxygen” will degas from the Earth’s core, increase the atmospheric pressure to 40 atm and the global temperature to over 80°C, or the hypothesis that the main internal heat source of the Earth is not radioactivity but “gravitational matter differentiation”. All these hypotheses are not well substantiated either by original arguments or by credible references. One of the weaknesses of the paper is that much of the cited literature is in Russian, thus not easily accessible, or refers to websites, some of them as dubious as http://www.junkscience.com. If the authors think that theories of anthropogenic global warming are junk science, they should themselves adhere to higher scientific standards, e.g., by citing the relevant literature in the fields they cover, but they fail to do so. Some of their major conclusions are simply unsupported allegations, e.g., when they claim that “the major causes of currently observed global warming are: rising solar irradiation and increasing tectonic activity”.
    Another example for the failure of Khilyuk and Chilingar (2006) to substantiate their claims and to refer to the state-of-the-art literature is their Fig. 11, showing a simplified picture of the global temperature curve of the past 1,000 years. Based on an article in the Bulletin of the American Association of Petroleum Geology, this figure shows the medieval warm period at +2°C and the little ice age at -1°C relative to the present. It certainly is not a fair representation of the intense recent debate about the global (or rather: northern hemisphere) temperature evolution over the past millennium. One might expect that the authors would refer to the famous “hockey stick” curve of Mann et al. (1998), which has been a major target of the criticism of climate change skeptics in recent years. Or to the latest attempt to reconstruct such a curve presented by Moberg et al. (2005), or other studies as summarized by Briffa and Osborn (2002). None of all these important papers are cited by Khilyuk and Chilingar (2006), instead it is claimed that “the global average temperature dropped about 2°C over the last millennium”, which is squarely at odds with the findings of all these studies.
    It is astonishing that the paper of Khilyuk and Chilingar (2006) (as well as Khilyuk and Chilingar 2004, for that matter) could pass the review process of a seemingly serious journal such as Environmental Geology. Such failures of this process, which is supposed to guarantee the quality of published literature, are likely to damage the reputation of this journal.

    ,,, but you have illustrated very nicely the quality of science typically practised or embraced by climate change skeptics, thank you. Another interesting quote;

    Here's why Khilyuk and Chilingar is the gift that that keeps giving: their mistake is so large and so obvious that anyone who cites them either has no clue about climate science or doesn't care whether what they write is true or not. But because there are so few peer-reviewed papers that support the global warming skeptic's position, it is almost irresistible for them to cite them

    ..." in interview for Discover magazine, Oct 1989

    Our knowledge of climate change has grown by such bounds in the (almost) 2 decades since that quote that you are doing exactly what Creationists do when they quote Darwin. Why not use a quote that is a little more up-to-date?

    So, let us review;

    1/ You consistently point out (I do understand you're passing on the skeptical arguments such as they are and may not be aware of how trasparent such arguments are as they are largely designed to convince laypersons, so don't take this personally, you've been taken-in) things which have nothing to do with the increase in CO2 levels due to human activity, pointing to water vapour's large role (which has precisely nothing to do with human-related CO2 increase), and pointing out CO2's small percentage increase (which doesn't mean this small increase can't have a large enough effect), quoting papers which claim man has not directly heated the atmosphere by more than 0.01 C (which has again nothing to do with CO2 increase due to human activity) and using twenty-year old quotes from the global warming lobby to try and build a case which will allow attention to be drawn away from all the evidence pointing to the current warming trend being a result of human activity.

    2/ You cite a paper which is becoming infamous on account of the spectacularly bad science and misleading argumentation it displays, yet one which will be quoted by global warming cynics for sometime to come as it is one of the only papers cynical to global warming to pass a peer-review process. This is similar to another "skeptics vs.a establishment" debate, that of ID/Creationism vs. Evolution, here (although un peer-reviewed) Behe's "irreducible complexity" claims will be aired for years to come, despite the fact they've already beent comprehensively rebutted. Oh, another similarity to the Crea/ID vs. Evo debate is the authors of a paper on CLIMATE CHANGE is by two people from USC's civil engineering faculty; Creao/ID is famous for papers by people working out of their specialism...

    I don't say this to suggest you are a Creationist or ID-ot, but to highlight the similarity of bad science and misleading claims that both ID/Creationism and globtal warming cynicism rely upon.

    I also don't say that Khilyuk and Chilingar themselves were funded by the petroleum industry or anything similar, but even with the P-o-S they HAVE authored, they NOW could get funding enough to be very comfortable, either as convenient idiot savants (they might actually be sincere) or knowing constructors of misleading arguments for the skeptical lobby.

    As for how their rubbish got published; according to ISI Web of Knowledge, based on citations/article, Environmental Geology ranks 143 out of 149 Environmental/Ecology journals. EG is not listed as a Geology journal, but if it were it would rank 172 out of 186.

    So, again, over to you; will you be annoyed at me for pointing out the mistake you've inadvertently made, or annoyed at the people who have actually mislead you? Will you accept K&C's article is utter bunk? Will you post something which shows recent warming is not linked to recent CO2 rises?

    Remember, that 0.03% slice has risen from ~280 ppm to ~380ppm in our present day. These levels are pathetically small compared to atmospheric levels in Earth's past (as much as 5000 ppm).

    The problem isnt actually warming per se. Its the speed of warming. We could evenually adapt if it was a slower process. Our infrastructure and especially our environment the biosphere are specifically adpated to the current temperature...it would take time for them to adapt to a warmer temp. If you get too abrupt a change then our ability economically and especially natures ability to adapt and evolve is greatly hindered. Now, there has been 6+ degree change in terms of a global average from the last ice age until now, and that happened over quite a period. 0.6 over just 100 years (the warming we have seen so far) in terms of a global average is quick. And according to the IPCC thats set to get quicker as the oceans thermal inertia kicks in, and it also stops acting as an effective carbon sink (it currently absorbs half of the c02 we emitt). The IPCC projects a rise of 1.5 -4.5 degrees for the doubling of c02. Thats set to happen somewhere around 2030-50 at current rates. They settle on a 2.5 C warming for the doubling of c02 (1.25 for direct c02 & 1.25 for feedbacks)

    And those pathetically small gases are responsible for a heating effect of 31oC BTW. The av surface temp of earth would be -16oC without them. Instead its 15oC. Co2 is responsible for atleast 9%+ of that warming...and considering that h20 is only ever a feeback process it can fairly be said to be responsible for even more of that warming called the greenhouse effect.
