| Url where found? Thanks, Thomas "Average global temperatures are now some 0.75 °C warmer than they were 100 years ago. Since the mid-1970s, the increase in temperature has averaged more than 0.15 °C per decade. This rate of change is very unusual in the context of past changes and much more rapid than the warming at the end of the last ice age. Sea-surface temperatures have warmed slightly less than the global average whilst temperatures over land have warmed at a faster rate of almost 0.3 °C per decade. Over the last ten years, global temperatures have warmed more slowly than the long-term trend. But this does not mean that global warming has slowed down or even stopped. It is entirely consistent with our understanding of natural fluctuations of the climate within a trend of continued long-term warming."

| Now about the MWP against CWP: ( from: http://www.co2science.org/data/mwp/mwpp.php) Figure Description: The distribution, in 0.5°C increments, of Level 1 Studies that allow one to identify the degree by which peak Medieval Warm Period temperatures either exceeded (positive values, red) or fell short of (negative values, blue) peak Current Warm Period temperatures. Level 1 Studies: Studies that allow a quantitative comparison to be made between the temperatures of the Medieval Warm Period (MWP) and the Current Warm Period (CWP). These reports are very important, especially those that reveal the MWP to have been warmer than the CWP and that were published after the papers of Mann et al. (1998, 1999) appeared, because the authors of such Level 1 reports likely knew that their findings were not in harmony with the contemporary position of the Intergovernmental Panel on Climate Change, which strongly endorsed the Mann et al. papers that claimed the warmth of the latter part of the 20th century was unprecedented over the entire past millennium. Authors of more recent Level 1 papers have additionally had to contend with the contrary force of the paper of Mann and Jones (2003), which claimed that the warmth of the latter part of the 20th century was unprecedented over the past two millennia. Hence, it can be appreciated that the authors of many Level 1 papers were really "sticking their necks out" when reporting something considered by much of the scientific community to be incorrect, which would tend to give special credence to the sincerity of their belief in the validity of their data.

when did generally agreed upon, become a fact this kind of cavalier use of "facts" is the basis of your argument please and you wonder why Im laughing at you guys Quote:
A) no one agreed on anything B) are you high again, whats this climate cooling for the last ~40 years tripe C) ends up with more than a few folks rolling on the ground laughing and this is getting really old Quote:
to which the only reasonable response can be no **** Shirlock sun does seem to have a lot to do with climate now doesn't it Quote:
one of them would be human interaction wouldnt it? and that is the crux of the mater is human interaction causing an effect on the global climate no one is arguing that the sun has nothing to do with it what were arguing is that 6,000,000,000 people also have an influence like we are eating every living thing on the planet and have demolished the ecosystem and altered the chemistry of the atmosphere and are pumping **** out of the depths of the earth as fast as we can tell you what you keep distracting the issue Ill keep bringing it back on track the factor we are questioning is human not wind or waves or swallows burping in Zimbabwe what was it 82~84 + million barrels of oil dumped into the ecosystem every day and you think that will have no effect are you nuts of course it will and that "fact" alone is bound to come home and bite you in the ass eventually |

"Previously reported discrepancies between the amount of warming near the surface and higher in the atmosphere have been used to challenge the validity of climate models and the reality of human-induced global warming. Specifically, surface data showed substantial global-average warming, while early versions of satellite data showed little or no warming above the surface. There is no longer evidence of such a discrepancy. This is an important revision to and update of the conclusions of earlier reports from the U.S. National Research Council and the Intergovernmental Panel on Climate Change. Since those reports, errors have been identified and corrected in the satellite data and other temperature observations. These data now show global average warming in the atmosphere similar to the warming observed at the surface and consistent with the results from climate models, although discrepancies remain to be resolved in the tropics. The recent evidence has increased confidence in our understanding of observed climatic changes and their causes." http://www.climatescience.gov/Librar...ft/default.htm And: "We find that there is no longer a serious and ubiquitous discrepancy between modelled and observed trends in tropical lapse rates."

| The statement about the warming rate being unusual is unsupportable. You can look at any number of recons and see some steep slopes sustained for a few decades at a time; no different than recent warming. Here's hard data for my statement about anthropogenic Co2: Global CO2 Emissions from Fossil-Fuel Burning, Cement Manufacture, and Gas Flaring: The first number is the year. The second is the total global CO2 releases in million metric tons: 1751 3 1800 8 1850 54 1900 534 1950 1630 2000 6745 Find the data here: http://cdiac.ornl.gov/ftp/ndp030/global.1751_2005.ems It's easy to see why the 1950's are generally agreed to begin the significant releases. This is a very interesting site and completely apropos the discussion: http://cdiac.esd.ornl.gov/epubs/ndp/ndp030/ndp0301.htm Then there's this: In a new scientific paper in the journal Energy and Environment, German researcher Ernst-Georg Beck, shows that the pre-industrial level is some 50 ppm higher than the level used by computer models that produce all future climate predictions. Completely at odds with the smoothly increasing levels found in the ice core records, Beck concludes, "Since 1812, the CO2 concentration in northern hemispheric air has fluctuated, exhibiting three high level maxima around 1825, 1857 and 1942, the latter showing more than 400 ppm." In a paper submitted to US Senate Committee hearings, Polish Professor Zbigniew Jaworowski, a veteran mountaineer who has excavated ice from 17 glaciers on six continents, stated bluntly, "The basis of most of the IPCC conclusions on anthropogenic [human] causes and on projections of climatic change is the assumption of low level of CO2 in the pre-industrial atmosphere. This assumption, based on glaciological studies, is false." Read the rest here Some good graphs of historical CO2 levels. Take special note, Thomas, of the rising CO2 levels way back before 1800, when our industrial output was miniscule; we exhale far more today(12 MMT)! This is quite important, because if the levels of CO2 in the recent past were actually substantially higher than the 'generally accepted' 280 ppm, that may indicate that current CO2 level rises are not from the use of 'fossil' fuels, but merely a natural fluctuation. http://www.warwickhughes.com/icecore/ ![]() Note that the 'knee' in the graph corresponds to circa 1950, the turning point in anthropogenic releases. But it's the part before the knee that I'm asking you to focus on because it proves my point: how could we be responsible for that bit of the rise given the paltry sums of CO2 we were the releasing Even AGW leaning scientists concede this point; why won't you? (Hansen admits that's why he chose 1958 for his study back in the 80's)I'll flesh out all the other 'facts' in my previous post later. I have to go to bed, now Jimbo |

| And this is from the University of Alabama See the attached graph. Find the raw data here: http://vortex.nsstc.uah.edu/public/m.../tltglhmam_5.2 Read Dr. John Christy: http://www.nsstc.uah.edu/atmos/chris...gless_etal.pdf From there: "5. Summary We have tested the proposition that greenhouse model simulations and trend observations can be reconciled. Our conclusion is that the present evidence, with the application of a robust statistical test, supports rejection of this proposition. (The use of tropical tropospheric temperature trends as a metric for this test is important, as this region represents the CEL and provides a clear signature of the trajectory of the climate system under enhanced greenhouse forcing.) On the whole, the evidence indicates that model trends in the troposphere are very likely inconsistent with observations that indicate that, since 1979, there is no significant long-term amplification factor relative to the surface. If these results continue to be supported, then future projections of temperature change, as depicted in the present suite of climate models, are likely too high. In summary, the debate in this field revolves around the idea of discrepancy in surface and tropospheric trends in the tropics where vertical convection dominates heat transfer. Models are very consistent, as this article demonstrates, in showing a significant difference between surface and tropospheric trends, with tropospheric temperature trends warming faster than the surface. What is new in this article is the determination of a very robust estimate of the magnitude of the model trends at each atmospheric layer. These are compared with several equally robust updated estimates of trends from observations which disagree with trends from the models. The last 25 years constitute a period of more complete and accurate observations and more realistic modelling efforts. Yet the models are seen to disagree with the observations. We suggest, therefore, that projections of future climate based on these models be viewed with much caution." I'm also going to bed. Nice dreams! Cheers. |

| this is exactly the kind of blatantly biased research Im talking about please people at least check your sources before offering such embarrassingly bad research for comparison good Gods and you wonder why Im laughing at this hole view when you once again have harped on Mann what is it every other post there is some rant about Mann's graph can we please at least hear a new argument rather than the same old tired diatribe from the same old tired industry cronies Quote:
the CO2 Science people and question there ability to perform an unbiased and quantitative study on anything let alone the effects of the pollution caused by there employers Quote:
any else know who the CO2 Science people are am I really the only one to catch this well there was a huge expose' done of em recently and they were laughed right out of Dodge gads I cant believe you actually quoted them G check your sources kids there are industry cronies being quoted right and left for instance these CO2 Science people that G is so fond of chairman CRAIG D.

| Boston, those are exactly the kind of contributions you just seem to able to do: personal attacks against people you consider are wrong (or plainly you do not understand or refuse to read) and trying to mix pears with apples instead of debating or at least posting useful data on anthropogenic CO2 warming, the only issue we are debating here. Tiring, disgusting and not useful at all, making all of us lose our time, both the warmists and 'cooliests', who are trying to maintain a minimally constructive and learning debate here. Could you please avoid doing that anymore? Please, please, please..... ![]() |

perhaps you prefer to have a look at more in deep discussions on the matter here: http://www.climateaudit.org/?cat=8 If you search there, you'll find a lot of studies suggesting warmer than today's temperatures at variety of locations around the globe, not only in Europe. Like these ones: http://www.climateaudit.org/?p=145 http://www.climateaudit.org/?p=1165 http://www.climateaudit.org/?p=378 http://www.climateaudit.org/?p=105 Of course the magnitudes of the MWP global temperatures are under strong debate, but I don't find position from defendants of lower than actual ones being better supported than the contrary.

| is it a personal attack to show ones work as biased and therefore subject to question is it a contribution to point out that research supporting an industries ability to continue its profitable pollution; is provided by that industry is it usefull to discuss the levels of co2 when you wont admit that human activity has something to do with those levels how does it help the discussion for detractors to refuse to admit that gigatons of waste spewed into the atmosphere every year, year after year is altering the atmospheric chemistry what you call disgusting is the basic logic through which your view of man having nothing to do with global climate change is shown to be untenable I regret I may be having a little to much fun with this I've always found it easy to demolish pseudoscience and following the funding is a real easy way to find out who is who and why they may believe what they do anthropogenic CO2 warming? I was under the impression the subject was Quote:
I maintain one of those factors is man the admission of which is key to our discussion concerning co2 is it so wrong to as doggedly pursue that admission as detractors pursue there own agenda the analogy of the blind leading the blind may not be as easy for some to accept when they consider themselves the leaders spoken of but in this instance it does seem to apply well as the level of blatant biased disinformation is extraordinary I think there was one viable reference made in the last twenty or so and that was a blatant distraction with the detracting view's basic logic being to try and argue that because one thing out of hundreds may be causing climate change, that something else, isn't you just wouldn't get to far at least not in any of the scientific or academic communities you have to admit when you tried to say the sun may have something to do with global climate change what was I supposed to do other than laugh I was rolling when I read that I mean please common seriously ya think the sun may have something to do with this hole climate thing really thats going to be funny to a lot of people there G it may have been a sarcastic funny to those who's view was being shown as sorta silly but it was kinda funny none the less tell you what if you and Jimmy admit that this vast number of people nearly 7 billion at this point is emitting massive amounts of waste products into the ecosystem and that that waste can only have an effect then I think this can begin to move forward a little I think the obvious reality that 97% is a consensus might also be best admitted because it represents a willingness to at least face the truth that was a Harris poll for Pete's sakes how can you guys possibly deny a Harris poll those are just two very simple beginnings that could seriously serve to help that learning process you mentioned best B |

| ok G so Im and try to make one simple point and see if it gets across first thing I do when Im offered information on an unscientifically moderated forum is check the source in your latest you mention http://www.climateaudit.org/?cat=8 so I go there and I see its a site by Steve McIntyre titled Climate Audit now that name rings a bell cause Ive seen his name come up before but to be thorough Ill look him up again Quote:
but it doesnt bode well for his work being unbiased nor is it evil to notice his education he studied rocks not climate science and has a bachelors degree in mathematics nor did I notice ( and I certainly may have missed something ) that he had actually published anything Im then going to notice the first thing it says in his bio is hockey stick controversy ok so now maybe some of the readers can see what Im getting at once again we are stuck on the Mann wagon if you go back about fifty posts you will find that I posted about twenty or so graphs of temperature vs time in response to this ongoing problem with the Mann graph. I tried to move on from it and give you the Mann graph if you would give me the other thousand or so your not mentioning as being fraudulent, but no hear we are how many months later with the Mann graph still out on the table a proverb begins to come to mind why am I watching this dead horse getting beaten to a pulp but to be fare I go on and every subsequent reference is from the same biased source the oil guy's page now seriously G in your own words Quote:
was any of this a personal attack was I to hard on any one did I manage to point out the obvious about that horse looking pretty dead from any angle did we really have to mention Mann again all I can do is continue to point out the obvious and hope rational minds consider that in a scientific debate, peer reviewed works hold a lot more ground than industry biased pseudoscience cheers B |
